Research on the modified component importance analysis method for traditional timber buildings based on load
The importance of traditional timber building components is of great significance to the assessment of the overall structural status of timber buildings.In order to clarify the importance of traditional timber building components,we developed a modified evaluation procedure based on load.The load distribution matrix was reconstructed based on load conditions and load redistribution,and the calculation method for component importance was improved based on load-bearing components.We took the main hall of Baoguo Temple,a typical traditional timber building,as an example,for carrying out the numerical simulation analysis,evaluating component importance based on the generalized stiffness,and analyzing the influence of each modification on component importance and the resultant change rate of the modifications to component importance.The results show that:the modified variation of the column class was-0.53%to 2.19%;that of the Liangfu class was-2.6%to 50.6%;that of the Puzuo class was-12.8%to 9.99%;that of the Tuan class was-7.6%to 6.9%.The component importance of the main hall of Baoguo Temple was:the column class>Tuan class>Liangfu class>Puzuo class.The modified importance of the column class and Liangfu class increased,but that of the Puzuo class and Tuan class decreased.This study could provide a reference for the structural state assessment and preventive conservation of traditional timber buildings.
