基于能量抗震设计方法研究及其在钢支撑框架结构中的应用

摘要
介绍了作者近年来关于基于能量抗震设计方法的研究工作。首先,说明了基于能量抗震设计与传统抗震设计方法的关系,指出合理的结构损伤耗能机制控制是实现基于能量抗震设计前提,并据此提出了基于能量抗震设计的框架。随后,介绍了基于能量抗震设计用能量谱,包括单自由度(SDOF)体系总输入能量EI谱、SDOF体系累积滞回耗能比EH/EI谱以及多自由度(MDOF)体系EI,MDOF谱与SDOF体系EI谱的关系,并基于这些谱关系给出了MDOF体系的总累积滞回耗能EH的确定方法。在此基础上,基于静力弹塑性分析方法给出了结构预期损伤部位累积滞回耗能EH需求的确定方法,据此结合构件的承载力和变形需求,进行构件层次的基于能量抗震设计。最后,针对某钢支撑框架结构,介绍了所建议的基于能量抗震设计方法的应用。
The research progress on the energy-based seismic design methodology by authors in recent years is presented.Firstly,the relation between energy-based seismic design methodology and traditional seismic design method is discussed.This work points out that a critical condition to realize an energy-based seismic design is that the structure should have a rational damage/energy-dissipation mechanism.Based on this condition,a framework of energy-based seismic design is proposed.Secondly,the energy spectra for energy-based seismic design,including the spectral input energy EI,cumulative hysteresis energy ratio EH/EI for single-degree-of-freedom(SDOF) system,and the relations between energy spectra of SDOF and MDOF systems are briefly introduced.According to the energy spectra,the method to determine the total dissipated energy EH is proposed,which further leads to the method to calculate the dissipated energy EH at the desired positions by using MPA.Therefore,the seismic design of structural elements can be performed based on the elemental dissipated energy EH,the strength demands and the deformation demands.Finally,the application of the proposed energy-based seismic design methodology is demonstrated by the seismic design of a steel braced frame.
