Study On Seismic Performance Of Timber Structure Of Guangyue Building Based On State Assessment Of Damage

The Guangyue Tower has been built for more than 600 years since the 7th year of Hongwu of Ming Dynasty(1374).During these 600 years,it has experienced the destruction of wars such as violent storms,lightning and lightning strikes,shaking of the mountains and the deserted horses,conquests,and fires.After more than 20 overhauls,it is forbidden to keep them intact,but local members also have cracks in the diameter,splitting of the leg,tilting of the bearing column,degradation of the leg,surface erosion and aging,bending,endurance deformation,decay,ring cracks,etc.Damage phenomenon.This article takes Guangyue Tower as a research object,analyzes the wooden structure,and studies the seismic performance of the damaged wooden structure.Through a field survey of the current status of the damage of the Guangyue Tower,the state of the damage of the Guangyue Tower is evaluated in conjunction with relevant national regulations,and the damage of the Guangyue Tower Analysis of the reasons found that the damage of Guangyue Tower was mainly beam and column damage,and the beam and column damage was mainly cracks.Use finite element software to establish a finite element model of the damaged Guangyuelou wooden structure for analysis;and the slip of the column foot to study the influence of various damages on the seismic resistance of the wooden structure.The repair of wooden structures provides some theoretical support.The article studies the seismic performance of the Guangyue Building by investigating the damage of the Guangyue Building,the modal analysis of the Guangyue Building model,the dynamic time-history analysis of the damaged Guangyue building,and the dynamic time-history analysis of the Guangyue building under different component damage.Through the combination of actual investigation and finite element numerical simulation,the seismic resistance of Guangyue Building under beam and column damage were obtained.It is hoped that it will provide more scientific theoretical basis and practical reference for the subsequent repair and reinforcement of similar historical buildings.
