项目摘要

The aim of this research is to establish the scheme and methodology of performance design, in which structural robustness and construction cost is balanced during the design procedure on the basis of common understanding about building performance between designers and customers. The following major findings were achieved :1.The performance-based design in USA and EU were surveyed, referring to which the main fame of performance design feasible to Japan practice was established with the four categories of performance, i.e., functional, undamaged, reparable, and life safe levels.2.The cost and techniques of actually repaired buildings that were damaged during the 1995 Hyogoken-nanbu Earthquake were investigated, through which the relationships between repair cost and damage level are clarified, and the reparability limit state was defined in a mathematical form.3.Seismic damage analyses of buildings were conducted by means of numerical simulator which was developed in this project, from … More which the evaluation method of residual deflection are proposed for the reparability limit design.4.Fracture performance of steel structures, the data of which were not sufficient in the past research, were experimentally investigated, from which the relationships between seismic hysteresis and fracture were figured out.5.A large amount of past test data on buckling behaviors of steel members were extensively surveyed, from which data-base required for performance design was established.6.The limit behaviors of non-structural elements such as curtain walls and window glasses and building equipment such as air condition, ventilation, electricity, sanitary, and machinery were investigated on the basis of actually sustained damage during the Earthquake. From this, their performance descriptions were activated in the same manner of structural skeletons.7.A guideline of performance-based design for whole steel buildings including structural, non-structural, and equipment parts was established. The guideline was published in a volume and distributed in a symposium. Less

本研究的目的是建立性能设计的方案和方法，在设计过程中基于设计师和客户对建筑性能的共识，平衡结构坚固性和施工成本。主要研究成果如下：1.对美国和欧盟的基于性能的设计进行了调查，参考日本实践中可行的性能设计的主要原则，以功能、未损坏、可修复和生命安全四类性能水平为基础。2.对1995年兵库县南部地震中受损建筑物的实际修复成本和技术进行了调查，通过修复成本与损坏程度之间的关系进行了研究。明确了可修复极限状态。3.利用本项目研制的数值模拟器对建筑物进行地震损伤分析，提出了可修复极限设计的残余挠度评价方法。4.对以往研究数据不充分的钢结构断裂性能进行了实验研究，得出了地震滞后与钢结构断裂性能的关系。 5.广泛调查了以往钢构件屈曲行为的大量试验数据，建立了性能设计所需的数据库。6.根据地震实际受损情况，对幕墙、窗玻璃等非结构构件和空调、通风、电力、卫生、机械等建筑设备的极限行为进行了研究。由此，它们的性能描述以与结构骨架相同的方式被激活。7.建立了包括结构、非结构和设备部分在内的整个钢结构建筑的基于性能的设计指南。该指南已成册出版并在研讨会上分发。较少的
