考虑须弥座台基影响的古建筑木结构原位动力测试及地震响应分析
In-situ dynamic tests and seismic response analysis of ancient timber structures considering the influence of Xumizuo pedestal
摘要
Abstract
To investigate the dynamic characteristics and seismic performance of ancient timber structures con-sidering the influence of Xumizuo pedestal,in-situ dynamic tests were conducted to obtain the natural frequen-cies and vibration modes of the structures.Finite element models of the upper timber structure and the overall structure considering the influence of Xumizuo pedestal were established and modal analysis was conducted to verify the rationality of the modeling method.Seismic response analysis was conducted on the upper timber structure and the overall structure under earthquake excitations.Results show that Xumizuo pedestal reduces the natural frequencies of the overall structure.The first three vibration modes of the overall structure are less af-fected by Xumizuo pedestal,while the fourth and fifth vibration modes are significantly affected.When the earthquake peak ground acceleration is 400 cm/s²,compared with the upper timber structure,the maximum ac-celeration response of the overall structure increases by 53.70%,the maximum displacement response increases by 43.86%,and the maximum inter-story drift angle increases by 26.62%.The dynamic coefficients of each model decrease with increasing excitation intensity.The influence of Xumizuo pedestal on the story shear force of the overall structure increases with increasing excitation intensity,with a maximum increase of 162.97%.关键词
