【摘要】 基于性能的结构设计是21世纪抗震设计的发展趋势,而新建结构的抗震设计与在役结构的抗震评估及加固设计则是减轻地震灾害的二个重要方面.对基于性能的结构设计方法进行了评述,并对性能设计理论在结构抗震性能评估与加固设计中的应用状况进行了分析,进一步指出建立在役结构抗震性能评估及加固理论与方法需研究解决的问题.更多还原

【Abstract】 Performance-based design is the development current of seismic design of the 21th century. Two important aspects of alleviating earthquake disaster are seismic design of new structures and seismic evaluation as well as the retrofit design of existing structures. The methods of performance-based design are reviewed in this paper. The actuality and existent problems are analyzed and that performance-based design is applied to seismic evaluation and retrofit design.更多还原
