2.Modern Service Design Thinking on Traditional Culture-Based Services: A Case Study of the Service Businesses in Suzhou Old Town Areas

Author:Shen, X;Lo, CH

Source:CROSS-CULTURAL DESIGN: APPLICATIONS IN CULTURAL HERITAGE, CREATIVITY AND SOCIAL DEVELOPMENT, CCD 2018,2018,Vol.10912

Abstract:This paper presents a case study that utilizes modern service design thinking techniques to investigate culture-based service businesses. The study is carried out in two heritage sites in Suzhou, which itself is a historical city located in the south of Yangtze River in China. Ethnographic methods are used to explore and collect the data. Service design thinking principles and methods are then applied to analyze the observed service businesses and identify common thematic issues and design opportunities. Service prototyping techniques are also used to review and rearrange a customer's journeys in the services. The result shows that modern design thinking concepts such as the user-centered approach can provide fundamental transformations to those services. It also illustrates a more cross-cultural development with the cross-cultural encounter between the modern design techniques and the traditional culture-based services.

3.Numerical simulation of the through-thickness cracking of concrete cover due to steel reinforcing bars corrosion

Author:Mirzaee, MJ;Alaee, FJ;Hajsadeghi, M;Chin, CS

Source:SUSTAINABLE BUILDINGS AND STRUCTURES,2016,Vol.

Abstract:Concrete cover cracking due to the corrosion of steel reinforcing bars is one of the main causes of deterioration in Reinforced Concrete (RC) structures. The oxidation level of the bars causes varying levels of expansion. The rebar expansions could lead to through-thickness cracking of the concrete cover, where depending on the cracking characteristics, the service life of the structures would be affected. In this paper, the parameters which influence the required pressure for concrete cover cracking induced by the rebar expansion due to corrosion have been investigated through detailed numerical simulations. ABAQUS finite element software is employed as a modelling platform where the concrete cracking is simulated by means of eXtended Finite Element Method (XFEM). The accuracy of the numerical simulations is achieved by comparison of the numerical results with experimental data obtained from the literature. The results reveal that the most effective parameter in the cracking process is the ratio of concrete cover depth to the rebar diameter. Using a previously proposed empirical equation and the numerical model, the time from corrosion initiation to the cover cracking is calculated and then compared to the respective experimental data.

4.PROCESS-DRIVEN CONCEPTS Digital agendas in studio teaching

Author:Diniz, N

Source:PROCEEDINGS OF THE 17TH INTERNATIONAL CONFERENCE ON COMPUTER-AIDED ARCHITECTURAL DESIGN RESEARCH IN ASIA (CAADRIA 2012): BEYOND CODES AND PIXELS,2012,Vol.

Abstract:This paper discusses studio design curricula using digital design as the medium to design process. The fundamental idea explored is that digital design thinking is fundamentally process driven as opposed to narrative driven and that digital design thinking leads to different way of conceptualising and solving design problems. The paper presents four studio case studies using different methodologies illustrating current digital design models. The types of studios chosen and the working methodologies adopted will be discussed in the light of understanding this shift of design conceptual thinking.

5.DESIGN ENIGMA A typographical metaphor for enigmatic processes, including designing

Abstract:Presenting a hard-to-predict typography-varying system predicated on Nazi-era cryptography, this paper illustrates conditions under which unrepeatable phenomena can arise, even from straight-forward mechanisms. Such conditions arise where systems are observed from outside of boundaries that arise through their observation, and where such systems refer to themselves in a circular fashion. This illustration aims to show the dilemma of scientific design research: Objective outsiders are mystified while those subjectively involved understand.

Author:Ivanovic, GW

Source:PROCEEDINGS OF THE 18TH INTERNATIONAL CONFERENCE ON COMPUTER-AIDED ARCHITECTURAL DESIGN RESEARCH IN ASIA (CAADRIA 2013): OPEN SYSTEMS,2013,Vol.

Abstract:The present research discusses the importance of human activity as a place-making coordinate, and proposes the Activity Counter Maps (ACM) as a methodology for visualizing people's social spaces. Through two case studies, the ACM were tested for creating representations of both intensity of occupation in public spaces and people's public distances combined into a unified "three-dimensional public shape". The research analyses the resulted images and discusses its possible applications for digital design.

7.MEASURING THE PERCEPTIVE INTRICACY OF THE CHINESE SCHOLAR GARDEN

Author:Wang, HF;Herr, CM

Source:PROCEEDINGS OF THE 22ND INTERNATIONAL CONFERENCE ON COMPUTER-AIDED ARCHITECTURAL DESIGN RESEARCH IN ASIA (CAADRIA 2017): PROTOCOLS, FLOWS AND GLITCHES,2017,Vol.

Abstract:The carefully orchestrated relationship between view and movement forms a core composition principle of Chinese scholar gardens to create poetic depth. We focus on one characteristic case study to examine the intricate spatial relationships between what is visible and what is accessible from the garden visitor's perspective. We examine the garden layout through a quantitative approach based on Visibility Graph Analysis. We identify a certain congruence between visibility and accessibility patterns, and propose that a network of strategically distributed overview spaces is employed throughout the garden to counterbalance tensions generated from disjunction between visibility and accessibility. The paper offers new insights into how quantifiable aspects of the garden can be used to generate qualitative perceptions of elegant restraint and compositional intricacy.

Abstract:Despite strong encouragement by government guidelines and promoting efforts by the software industry, BIM is adopted at relatively slow speeds in construction industries across the world. The study presented in this paper examines the challenges to BIM adoption faced in particular in the Chinese construction industry across architecture, engineering and construction. We review recent literature addressing BIM adoption, develop a critique of common approaches to BIM adoption, and then propose our own, extended model to describe and assess BIM adoption processes. To demonstrate the model's suitability to evaluate temporal and collaborative dimensions during BIM adoption processes, we present results from a detailed survey we conducted among Chinese AEC professionals based on the extended model of BIM adoption and discuss how current Chinese BIM adoption in practice diverges from overseas BIM adoption strategies.

Abstract:The paper presents the geometrical investigation of a three-dimensional dovetail joint that can lead (timber) frame construction to more than two-dimensional frames; the creation of timber construction with timber members meeting at irregular angles can be shown to be feasible, simplifying overall construction. Traditional joints in timber construction usually work only in two dimensions, in other words in planar surfaces, resulting thus in complicated assemblies in three-dimensions. Stemming from traditional timber dovetail joints, the universal joint under investigation is produced under revolution of the geometry of a dovetail fastener through its middle axis. The resulting concave disk can connect timber elements under irregular angles, without the need for the structural members to lie in the same plane. The joint works due to friction between members rather than using any other element of bonding, allowing for the assembly of joints and structural members with no specialized tools. The paper explores the geometric constraints and degrees of freedom that such a disk creates in timber construction, and consequently in similar linear construction systems.

11.A Simulation Based System for Manufacturing Process Optimisation

Author:Ismail, HS;Wang, L;Poolton, J

Source:2014 IEEE INTERNATIONAL CONFERENCE ON INDUSTRIAL ENGINEERING AND ENGINEERING MANAGEMENT (IEEM),2014,Vol.2015-January

Abstract:Simulation models have been extensively used in manufacturing to enhance the design, planning and decision making processes. However, the tendency has been to use simulation in one-off applications, often at the start of a project and not take account of inherent process changes over time. This has inhibited their contribution as a real-time decision make tool. This paper describes how simulation is used as a component of an integrated optimisation platform to support real-time decision making in a highly variable manufacturing process environment where outputs are stochastic. The paper follows by proposing an integrated framework for addressing issues of process variability in simulation based systems.

Abstract:Ethics is becoming one of the most important requirements for successful business in the 21st century. The construction industry cannot be exceptional from this trend. However construction ethics management requires different approaches from other industries, as the products of the industry are construction projects which are completely different from mass production. Contractors and designers are two major participants in construction projects. The roles and responsibilities of these two project stakeholders decisively influence all aspects of construction project. Practically ethical perceptions of contractors and designers are one of main aspects to be considered for the effective and efficient management of ethics for the construction industry. This research has investigated the ethical perceptions of contractors and designers in the China construction industry. A questionnaire survey which contains 15 ethical issues and 6 demographic factors has been conducted. 170 construction professionals from construction companies and consulting companies have been participated in this survey. These 15 ethical issues are ranked in terms of seriousness, frequency and importance for both contractors and designers as a single group to understand the overall perceptions in the industry. The analysis has also been conducted for contractors and designers respectively to make comparisons between them. The top three serious ethical issues in the industry are 'Bribery and corruption', 'Failure to practice whistle-blowing' and 'Improper bidding practices'. Contractors and designers showed similar outcomes for the top five important ethical issues. But for the middle ranged ethical issues, they showed some differences. Further researches are required to identify the causes of the similarity and differences.

14.Flexural test of Tee steel PEC beam

Author:Zhao, BC;Chen, XD;Liu, S;Xia, J

Source:SUSTAINABLE BUILDINGS AND STRUCTURES,2016,Vol.

Abstract:To investigate vertical load-bearing capacity of Tee steel PEC beams, test results of two simply supported Tee steel PEC beams under vertical loads are presented. The procedure and method of test was introduced. The carrying capacity and failure mechanism, deformation capacity, mid-span sectional strain distributions were analyzed. The result indicates that the Tee steel PEC beam has good carrying capacity and deformation ability under vertical loads. Tee steel PEC beam specimens with full shear connection exhibit cross sectional strains that meets the flat section assumption. To avoid brittle failure of Tee steel PEC beams, the composite beam should have a larger steel ratio. It is rational that the plastic neutral axis is located in the flange of the concrete plate. Specimens with higher steel ratios have a higher bending strength and stiffness.

15.Hysteretic behavior study of Y-Eccentrically Braced Frames with end-plate connected replaceable links

Author:Shi, FM;Zhao, BC;Tang, C;Xia, J

Source:SUSTAINABLE BUILDINGS AND STRUCTURES,2016,Vol.

Abstract:In order to investigate the hysteretic behaviors of Y-eccentrically braced steel frames with end-plate connected replaceable links, fourteen specimens of three series have been designed, concerning the arrangement of bolts, the number of bolts, the diameter of bolts, the thickness of end-plate of the link and the thickness of beam flange. The finite element software ABAQUS is adopted to simulate the hysteretic behavior of these series of specimens so as to analyze the effect of the relevant design parameters on the performance of hysteretic behavior, bearing capacity, lateral stiffness and the energy-dissipation capacity of Y-eccentrically braced steel frames in this paper. The results indicate that the behavior of Y-eccentrically braced steel frames with end-plate connected replaceable shear links is less affected by the connection. Only if the connections are so weak that joints fail earlier than the link will the behavior of the frame suffer a lot from the effect. In addition, the connection construction exerts a significant effect on the replaceable behavior of the link.

16.NON-TRIVIAL MEDIA FACADES

Author:Herr, CM

Source:PROCEEDINGS OF THE 17TH INTERNATIONAL CONFERENCE ON COMPUTER-AIDED ARCHITECTURAL DESIGN RESEARCH IN ASIA (CAADRIA 2012): BEYOND CODES AND PIXELS,2012,Vol.

Abstract:This paper presents a discussion of contemporary interactive media facades that complements the currently primarily technical framing of this field of research. Media facades, in the form of digitally orchestrated facade illumination, are discussed here as sites of potential encounter and interaction that form part of the public sphere. These aspects seem both underestimated as well as underused as media facades tend to be limited to pre-programmed and primarily ornamental trivial response patterns, or to serving as oversized displays. This paper discusses media facades from an architectural rather than a technological perspective and critically assesses the promises of interactivity as well as implications of such facades on urban public space.

Source:Proceedings of the 19th International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2014): RETHINKING COMPREHENSIVE DESIGN: SPECULATIVE COUNTERCULTURE,2014,Vol.

Abstract:In this paper we report on the ongoing development of a toolkit to support the design of column and beam layouts for reinforced concrete structures in China. We present a visual, human-and machine-readable notation for architects and structural engineers to rapidly model column and beam layouts, as well as our underlying considerations. In conjunction with the toolkit, which consists of a CAD package, an editor, a parser, and an interpreter, the notation addresses aspects of local construction practice and supports design considerations including appearance, structural viability, constructability, and cost.

19.OPTIMIZATION OF WINDOW-WALL-RATIO USING BIM-BASED ENERGY SIMULATION

Author:Zhang, C;Ong, LJ

Source:PROCEEDINGS OF THE 22ND INTERNATIONAL CONFERENCE ON COMPUTER-AIDED ARCHITECTURAL DESIGN RESEARCH IN ASIA (CAADRIA 2017): PROTOCOLS, FLOWS AND GLITCHES,2017,Vol.

Abstract:In this research, sensitivity analysis is applied to investigate the impact from U-values of walls, U-value of windows, and the window-to-wall ratio. The purpose is to find the co-relationship between those parameters with the building energy performance, including embedded energy in materials and operational energy during the lifecycle. Building Information Modeling (BIM) is used as a platform to obtain the material quantities and carry on energy simulation. A case study is applied for a manufactory plant in Suzhou, China. By applying both local sensitivity analysis and global sensitivity analysis, it is found that thermal properties of walls have insignificant impact on Operational Energy to Embodied Energy (OE-EE) relationship of Window-Wall-Ratio (WWR) whereas changing thermal properties of windows affects the OE-EE relationship behaviour of WWR. Lowering U-value of windows brings positive impact to the OE-EE relationship of WWR, and vice versa. Therefore, suggestions are made as reducing/increasing U-value of windows while increasing/decreasing the WWR of building.

20.Building energy management based on occupant location

Author:Pazhoohesh, M;Zhang, C

Source:SUSTAINABLE BUILDINGS AND STRUCTURES,2016,Vol.

Abstract:Reducing building energy consumption has received growing attention in the recent decades. The primary energy consumption in buildings is related to heating, ventilation, cooling, and lighting systems. A well-design control system may result in a significant reduction of energy usage. This paper presents and implements three strategies to control and analyze energy consumption in buildings. The schedule, real-time monitoring and a multi-agent system are compared with the baseline energy consumption in a university office. Devices and human agents are introduced to investigate the real-time trend in energy usage and to optimize the consumption of energy, based on the location of occupants. Initial results demonstrate potential energy saving of 16%% in the office.
