体系能力设计法与基于性态/位移抗震设计
|
摘要
首先论述了基于性态 /位移抗震设计方法的发展及其需解决的问题 ,综合了结构抗震耗能原理、破坏机制控制概念、抗震体系和能力设计法等结构抗震原理 ,提出了体系能力设计法思想。体系能力设计法要求结构具有多重抗侧力抗震体系 ,并对不同子抗侧力结构采用不同的抗震能力 ,通过对抗侧力体系间能力差的控制 ,以实现主体抗侧力结构对整体结构在地震作用下的位移模式和破坏机制控制 ,进而使得整体结构的弹塑性地震响应和耗能分布的规律便于把握和确定 ,从而解决了基于性态 /位移抗震设计方法中的一些难以确定和计算的关键问题。最后通过一实例介绍了体系能力设计法的应用 ,并讨论了实现体系能力设计法基本概念和需进一步研究的问题
The problems in developing the performance/displacement based seismic design are firstly presented.With the energy theory,failure mechanism control concept,structure system and capacity design method in earthquake resistant structures,a structure system capacity design approach is put forward.The multi-structure aseismic structure systems are needed for the structure system capacity design,and the substructures have different seismic resistance capacity.With the control of seismic resistance capacity between the substructures,the displacement mode and failure mechanism can be controlled by the main substructure.And thus,the inelastic seismic response and energy dissipation distribution can be determined,which is the key problem in developing the performance/displacement based seismic design.A practical example that using the concept of the new suggested approach is finally presented and the problems need to be further studied for the approach are also stated.
