Stability Analysis and Evaluation of the Screen Wall of Huaide Hall in Liukeng Village,Le'an
Huaide Hall in Liukeng ancient village in Le'an,is famous for its screen wall with artistic and human-istic value.The stability analysis and evaluation of the screen wall of Huaide Hall is a problem to be solved in for-mulating a medium and long-term reinforcement and protection scheme.The numerical simulation model of the whole structure including the roof system,beams,columns,and screen wall is constructed.Through the inverse analysis,the current disease characteristics of the screen wall of Huaide Hall are reproduced,and the material characteristic parameters that can characterize the current situation of the screen wall are obtained.The develop-ment of the plastic failure zone,the deformation trend,and the overall stability of the screen wall under the differ-ent degrees of deterioration are evaluated.The results show that the overall stability of the screen wall of Huaide hall is good in the existing state,but with the deterioration of the brick wall materials and the continuous develop-ment of wall deformation trend,the brick carving finish blocks of the screen wall will squeeze,peel and stagger each other,and lose their artistic and cultural value.The research results provide support and a basis for the for-mulation of the reinforcement and protection scheme of the lighting wall of Huaide Hall.
