However, many high isolation buildings have been built around the world in recent years, which do not follow the existing criterions and codes. Many researchers began to research the special problems caused by larger height-width ratio isolation structures. The overturning effect of high height-width ratio structures with rubber bearing is firstly studied. Considering the main factors, such as the height-width ratio of structures, type of site, the designed basic acceleration of ground motion and the decouple factor in horizon, computing experiment is defined with the Uniform Design Method, which is also known as designing isolation structure. The forces of the bearing under edge of structures based on the position of the rubber bearing are calculated. The result indicates that the rubber bearings will lose its functionality under very high tension and compressing force of earthquake motion in horizon and vertical, when the height-width ratio is over a certain value. Thus, based on the calculation result of isolation structures defined in the uniform design method, regression analysis is conducted, and also the rubber edge force regression formula are gotten, which has higher correlation and smaller standard deviation. This formula can be used to roughly calculate whether the pull force occurs at the edge of the building. By the edge bearings of isolation structure minimum force formula, the height-width ratio limited value of the isolation structure is deducted when rubber bearing has minimum force of zero.展开更多

This approach is expected to foster the students＇ design skills in design studios. The approach is an educational tool for tutors that could guide the students and increase their creativity in their design. It considers the concepts and the practice of digital architectural design that influence architectural education. The approach is a catalyst for creativity, experimentation, critical thinking and the sustained growth of creative communities. The core of design studio is the notions, methods and skills of digital architectural design. The instruments used for this research was an investigation that made for the work of the fourth year students designs at the architectural department at University of Jordan, by testing design process and product of students＇ work： first using manual skills, and then using computer-aided programs. The results revealed that the computer-based design approach was able to foster students＇ design skills as well as to develop their creativity in design. Ninety-one percent of 44 students were found improved in design process using computer-based approach that depends on computer programs. This was done in design studio by improving students＇ way of thinking, developing their abilities to direct their own learning and pushing them for new definitions in developing their future work.展开更多

This paper aims to establish a prototype of workflow management system for construction design project through the application of workflow technology. The composition and function of prototype is presented to satisfy the needs of information share and process integration. By integrating all subsystems and modules of the prototype, the whole system can deal with design information-flow modeling, emulating and optimizing, task planning and distributing, automatic tracking and monitoring, as well as network service, etc. In this way, the collaborative design environment of building design proiect is brought into being.展开更多

The difficulty lies in how to apply the treatment without destroying the old components and the original design of the building. The treatment processes take place by the classification of the type and the value of the building, then the determination of the deterioration level decides the level of intervention. The aim of the research is to provide a method for assessing the ways of preserving the architectural and urban heritage, which includes all the factors that affect the preservation of the heritage so as to access that it contributes to access to the deficiencies in the ways of preserving the heritage and to build a plan for action to avoid them in the future. The research followed a causal comparative research approach that began with an analytical study to determine the factors affecting preservation and its considerations, by collecting and analyzing the data of the most important international and national charters and recommendations for the preservation. This study defined the preservation works into 4 levels of interventions passed on the intervention objectives, building＇s physical state, causes for the deterioration and maintenance works. By comparing the deterioration level with the intervention level for the conservation procedures, the result indicates the suitability of the work performed. This result could be number between 4 and -4.展开更多

More and more architecture, engineering, and construction companies are adopting new technologies in software design to help accelerate and accurately carry out their functions. Based on a research study carried out in Southern Nevada with a questionnaire survey of 54 construction-related firms, this study aims to compare the types and extent of IT use by architects, engineers, and contractors. It also explores the level of IT skills possessed by professionals working in the industry. The study found that architects mostly used design software whereas engineers and contractors used scheduling and estimating software. All of the respondents believed that IT helped to improve their work productivity. The majority of the respondents thought that IT is useful for Construction Management （CM） students： engineers and architects thought that CM students should take more scheduling and estimating software courses and contractors thought that they should take more scheduling and quantity take-off software courses.展开更多

Based on the finite element theory this paper designs adding process of insulation material EPS in the thermal insulation layer, and establishes the radiation heat conduction model of EPS material, finally obtains the solid heat conduction equation. Finally this paper uses ANSYS software to do simulation on the strength and temperature of EPS construction, and evaluates the quality of construction works, which provides technical reference for the design of integrated thermal insulation buildings.展开更多
