ABSTRACT The main assumption in seismic design procedures for structural systems is to provide the building with a high level of structural performance, subjected to earthquake loads. Such demand for higher performance needs additional investment on the project. In this work by taking into account the socio-economical aspects of the project, a value-based design approach is used to rationalise the structural design procedure in terms of initial investment. Determination of value design point in this approach is based on providing the optimality criterion from a global perspective. According to the results of this study, while for hospitals located in small cities with no substitute functionality in case of earthquake incident using base isolation for the structural system is quite necessary, for large cities, construction of fixed-base hospitals can still be permitted. The study also shows that, in the countries with higher growth rate, the required structural capacity to deal with earthquake demands in value-based design approach is lower than that required for low growth rate regions.

基于价值的基础隔震结构系统设计方法

摘要 结构系统抗震设计程序的主要假设是为建筑物提供高水平的结构性能，承受地震荷载。这种对更高性能的需求需要对项目进行额外投资。在这项工作中，考虑到项目的社会经济方面，基于价值的设计方法被用于根据初始投资合理化结构设计程序。这种方法中价值设计点的确定是基于从全局角度提供最优性标准。根据这项研究的结果，对于位于小城市的医院来说，在发生地震时没有替代功能的结构系统使用基础隔离是非常必要的，对于大城市来说，仍可允许建设固定基地医院。研究还表明，在增长率较高的国家，基于价值的设计方法应对地震需求所需的结构能力低于低增长率地区所需的结构能力。
