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.

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.

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.

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.

8.A Simulation Based System for Manufacturing Process Optimisation

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.

10.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.

11.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.

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.

14.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.

15.Building energy management based on occupant location

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.

Abstract:Lab-based teaching in which hands-on experiments are to be conducted by students takes an important part for a wide range of engineering and science disciplines. In our current practice, the lab-based teaching involves live demonstration and tutorials after the off-line lab manual review. This has become particularly problematic when the number of students is large and insufficiency on the lab-supporting system becomes a common issue. In the meantime, even with a small number of students, it can be interesting to prepare the lab in a one-to-one tutorial. Well-designed video tutorials eliminate the time and space constraints on learning and provide comprehensive details to students to enable them focus on deepening the understanding of concepts, rather than spending majority of time on trouble shooting during the lab. With the full technical support from the Digital Learning Resources Hub at Xi'an Jiaotong-Liverpool University, we propose to involve student volunteers to generate a series of customized video tutorials for our electronics lab-based teaching practice. From the viewpoint of students themselves, these video tutorials are carefully designed based on students' learning needs to seamlessly integrate a wide range of theoretical and practical information. Under the supervision of staff, volunteers will be able to repeat their learning cycles with a different role and enhance their own understanding and knowledge structures, promoting the student-centered education model. Some scenery-based video tutorials will be used in the online quizzes questions to better prepare the students. The generated video tutorials will be shared across a number of electronic engineering modules to further investigate the effectiveness of these video tutorials. The effectiveness can be further explored using online questionnaires and online quizzes and evaluated by comparative studies.

17.A review on Agricultural Fibre Reinforced Concrete

Source：SUSTAINABLE BUILDINGS AND STRUCTURES,2016,Vol.

Abstract:The construction industry has undergone rapid development during the last few decades. This significant construction growth has substantially increased the demand for construction materials. Among all materials used in the construction industry, concrete is the most significant. Billions of tonnes of naturally occurring minerals are mined for the production of concrete which has left a big gap in terms of sustainability of the construction industry. To overcome this drawback, the search for durable and sustainable construction materials is currently needed. The world of concrete with fibres has been in continuous research and also in use. However, manmade fibres though enhanced the properties of traditional concrete, are not sustainable and economical. This paper presents a brief review of fibres from agriculture wastes that have been in research and application as potential next generation construction materials. The micro-structure and properties of Agriculture Fibre Reinforced Concrete (AFRC) are described and some current possible applications are mentioned. Various methodology, emerging trends as well as variations in modification techniques for agricultural fibre modified concrete are observed. Several recently published articles and technical papers dealing with such fibre modified concrete are critically reviewed.

18.Reflective Practice: Lessons Learnt by Using Board Games as a Design Tool for Location-Based Games

Abstract:Location-based gaming (LBG) apps present many challenges to the design process. They have very different requirements compared to games that are aspatial in nature. They take place in the wild and this brings unique challenges to the practicalities of their design. There is a need to balance the core game play with the spatial requirements of location-aware technologies as well as considering the overall theme and objectives of the game together with the motivations and behaviours of players. We reflect upon this balancing act and explore an approach to creative paper prototyping through the medium of board games to co-design LBG requirements. We examine two case studies of location-based games with different goals. The first case study discusses the CrossCult Pilot 4 app built to trigger reflection on historical stories through thoughtful play. Whilst the second case study uses the City Conquerer app designed and played in Suzhou, China with a view to exploring notions of territoriality. The paper considers how spatial, social and interaction metaphors are used to simulate location-based games in a board game and discusses the lessons learned when transforming the paper game into a digital prototype. It forms part of a thinking by doing approach. By comparing the board games to the technical counterparts, we consider how effective are the features and activities implemented in the technology prototypes. We propose a set of 11 design constraints that developers must be mindful of when transitioning from paper to digital prototypes.

19.Current state of information exchange between the two most popular BIM software: Revit and Tekla

Author：Nizam, RS;Zhang, C

Source：SUSTAINABLE BUILDINGS AND STRUCTURES,2016,Vol.

Abstract:Information exchange between domain-specific software products is essential for capturing the life cycle information of a building from its inception to operation. To collect all specialized information within a single model requires a platform that is acceptable to all different software tools. Many researchers have suggested that this objective can be approached by using vendor-neutral and open building information models such as the Industry Foundation Classes (IFC) to capture and exchange data. To analyze the effectiveness of the IFC model, this paper presents a data exchange analysis between two of the most popular BIM software to date: Revit and Tekla. Models are exchanged in the two software using IFC and a comparison is made in terms of data loss and misrepresentation. Revit seems to process IFC data easily however minor changes are noticed during the exchange. Tekla needs conversion procedures before IFC data can be processed. The architectural features of the model are found to be seriously misrepresented in Tekla.
