Study On Horizontal Force Performance Of Foam Concrete Wallboard With Different Height-Width-Ratio

With the rapid development of Chinese domestic construction industry,new forms of architectural structures are also increasing.In recent years,with the rapid development of Chinese housing industrialization,the prefabricated building structural system has become a new type of structural system that I have focused on.However,as one of the more important components in the prefabricated building structural system,prefabricated wall panels have attracted the attention of a wide range of scholars.The foam concrete wallboard to be studied in this paper is a new type of assembled wallboard in the process of Chinese housing industrialization.This wallboard has the advantages of convenient construction,low cost,environmental protection,energy saving,and the like.Since the foamed concrete has a small self-weight and a large number of internal voids,it can save material and reduce costs by reducing its own weight in the building structure.At the same time,the foamed concrete wallboard with many internal voids also has the characteristics of a sponge.When subjected to an earthquake disaster,the structure has a good energy absorption effect and can reduce the earthquake disaster.Therefore,in the era of assembly-type and housing industrialization,the implementation of foamed concrete wall panels can promote the rapid development of fabricated structures.In this paper,the ABAQUS finite element software simulation analysis is used to study the horizontal bearing performance of six different aspect ratiofoam concrete walls,to further analyze the seismic performance of foam concrete wall panels,and to provide a theoretical basis for the practical application of foam concrete wall panels into engineering construction.The main research contents of this paper are as follows:1.Based on the analysis of the ABAQUS finite element simulation theory,the basic model is established by the ABAQUS finite element software.2.Through ABAQUS finite element software,finite element simulation analysis was performed on six ordinary foam concrete wall panels and diagonal reinforcement foam concrete wall panels.The finite element simulation cloud map and data results were compared and analyzed,and the damage characteristics and ductility of the model were analyzed.Performance,hysteresis,energy dissipation,load capacity,and stiffness degradation.The anti-seismic performance of foam concrete wall panels with the same aspect ratio but different anti-seismic measures was compared.3.I have established a calculation model for the restoring force of diagonally reinforced foam concrete panels.On the basis of ordinary foam concrete wallboard,change the distribution of reinforcing steel,we recalculate the calculation formula for the diagonal reinforcement foam concrete wall panels,and establish the calculation formula for the stiffness of the foam reinforcement concrete wall panels with diagonal reinforcement and the calculation formula for the bearing capacity.4.To propose structural optimization recommendations for diagonallyreinforced foam concrete wall panels to achieve the best seismic performance.
