Analysis of Structural Properties and Seismic Performance of a Temple

In order to further study the seismic mechanism of ancient timber structure, the wooden structure of the temple was taken as the research object, and the reasonable mechanical model was established by applying semi-rigid spring element to simulate mortise-tenon joint, tou-kung and column base. The test of the compressive, bent and the shear capacity all met requirements by analyzing the model under the static load, and the average safety margin of the structure is 86.7%. The first six inherent frequencies and vibration shapes were obtained by analysing the finite element model using the method of Block Lanczos, With full transient analysis, considered the model in the El-Centro wave, Taft wave and Lanzhou artificial wave excitation under the three earthquake time history analysis, and got the model acceleration time history curves, the results show that the ancient Chinese timber structure has better aseismic performance. The above-mentioned methods and corresponding conclusions could provide the reference for maintenance and protection of ancient Chinese timber structure.
