Ceramsite Concrete Sandwich Thermal Insulation Wallboard In Frame System Seismic Performance Analysis

At present,the new development concept has gone deep into the hearts of the public,the new era of China’s green building development is more about the national livelihood.In the construction industry,the application of new composite wallboard in structure plays a very important role in green development.As a new type of assembled composite wall Board,the ceramic concrete sandwich core has the advantages of heat preservation,energy saving,green economy,and convenient construction.Therefore,the application of the ceramic-concrete sandwich-insulated wallboard in the structural system will be a key topic in the future research.Based on the research results of the research group,in order to further study the applicability of the composite wallboard in the structure,this paper focuses on the seismic performance of the ceramsite sandwich self-insulation wall panel under different stiffness framework by using the finite element software.The main contents of this paper are as follows:the research data of the research group and the constitutive model of concrete structure design(GB50010-2010)are used to calculate the plastic damage model of ceramsite concrete.The single composite wall Frame,the different hysteresis characteristics and ductility of the system under low cyclic loading.The consolidation data are analyzed and the application scope of the new composite wallboard to the frame stiffness is proposed,which provides data support for the application of the new composite wallboard in the structure.The results show that the new composite wall frame system has better ductility and elasticity than the single frame and individual wall panels,and the structure has good seismic performance.The composite wallboard and the frame have good working performance;Analysis of the ductile coefficient and equivalent stiffness data,the composite wall board to obtain the framework of the stiffness range.The research of the research object provides important data reference for the application of the ceramsite concrete sandwich self-insulation wall board in the frame structure system engineering,and provides theoretical support for further popularization and construction application.
