Aseismic Effects of Masonry Walls Embedded in Chinese Ancient Wooden Buildings by Wen-chuan Earthquake

摘要

In order to protect Chinese ancient buildings, a wooden building in Guangyuan city in China is taken as an example to study aseismic effects of masonry walls to wooden constitution by Wenchuan earthquake. By ANSYs PROGRAM, semi-rigid character of tenon-mortise joint as well as contact between wooden constitution and walls are simulated. Then finite element model of the building is built. By comparison method, vibration modal as well as dynamic responses of the structure before and after considering wall effects are studied. Results show that after considering embedding effects of masonry walls, main mode of the ancient building is mode 1 in x direction. Under Wenchuan earthquake the wooden constitution produces lower displacement but higher acceleration values.
