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
Study on energy-based application on steel seismic design method and braced frame structures
摘要
Abstract
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 E1, cumulative hysteresis energy ratio Eu/EH 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 En 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.关键词
