古建筑木结构基于结构潜能和能量耗散准则的地震破坏评估
Potential and energy dissipation-based seismic damage evaluation of ancient timber structure
摘要
Abstract
In order to investigate the failure process and corresponding failure mode of the ancient timber structure so as to be able to make a reasonable evaluation of the damage degree of the ancient timber structure after earthquakes,the ’potential of destruction-resistance’ of the two energy-consuming components under low cycle reversed loading was calculated based on the hysteretic behavior and energy dissipation principle of the dovetail column-frame and arches brackets under low reversed cyclic loading.The dissipated energy of each energy-consuming component under various earthquake conditions was calculated based on the results of shaking table tests of ancient timber structure.The model for the seismic damage evaluation of the two energy-consuming components was established on the basis of the ’potential of destruction-resistance’ and the dissipated energy.The relationship of the failure state between energy-consuming components and overall structure was found by means of the energy distribution coefficient.The model for seismic damage evaluation of the overall structure under various earthquake conditions was also developed.With the derived model for seismic damage evaluation,the energy-consuming components and the overall structure can be evaluated respectively.The resulting failure coefficient can better reflect the failure state of each component and the overall structure under various earthquake conditions.The research results can provide a reliable theoretical basis for the seismic reinforcement for the ancient timber structures.关键词
