摘要
通过大量复杂超限工程大震弹塑性时程分析的研究,提出了基于大震弹塑性时程分析的结构抗震设计理念。详细介绍了该设计方法的设计思路,并将其应用于各种复杂超限工程中。通过对具体案例的详细分析表明,基于大震弹塑性时程分析的结构抗震设计能够作为一种主动设计手段,指导设计人员有针对性地进行结构方案调整和局部构件调整,优化结构设计,在提高结构安全性的同时实现经济性。因此,基于大震弹塑性时程分析的结构抗震设计能够进一步完善我国现有的两阶段抗震设计方法,值得在结构抗震设计领域中推广。
Structure seismic design based on elastic-plastic time-history analysis of severe earthquake was proposed from a large number of analyses of complex structures.Design process was introduced in detail,and the design method had been used in all kinds of complex structures.The detail analyses of application examples indicate that structure seismic design based on elastic-plastic time-history analysis of severe earthquake is an initiative design method to help designers to adjust structure arrangement or elements more purposefully,and it can optimize design to improve the security of structures more economically.So the structure seismic design method based on elastic-plastic time-history analysis of severe earthquake perfect the present seismic design method,which can be popularized in structure design.
