Retrofit Design and Seismic Performance Analysis of a Historic Hall in West Jiangxi Province
A historic Hall is located in Yuanzhou County,Yichun City,Jiangxi Provinces.It was built in the Qing Dynasty.It is the heritage protection unit of Yichun.This Hall is a typical masonry and timber structure in west Jiangxi province.The timber structure is in the interior and the hollow brick wall is in the outside.Because of the bad maintenance and the fire,the hall is badly damaged.Firstly,these structural damages were analyzed and judged in this paper.In the same time,the results of safety appraisal were considered.The remedy method of overhauling and rebuilding was presented in this paper.Secondly,the simulation of masonry and timber structure was presented in this paper.And the spatial model was built and analyzed.By the results of calculation,the restoration disposes of the damage elements,such as masonry wall,timber beams and timber columns,were presented in this paper.The ring beam and construction column were arranged in hollow brick wall,which improved the structural integrity.This new design method was applied in this project.Finally,by nonlinear time history analysis under different intensity earthquake,the seismic capacity and the holistic property of this building were improved.These repair and calculation methods can offer references to the similar structures in west Jiangxi province.
