An Experimental Study About Mechanical Properties Of Foam Concrete Composite Wall Panels

In recent years,the industrialization of housing in China has developed rapidly,the assembly wall is widely used in the construction industry because of its flexible layout.The foam concrete composite wallboard studied in this paper is a kind of new type of wall,with convenient construction,good integrity,low cost,short construction period,building the advantages of higher quality,especially significant in energy saving,environmental protection,development of circular economy.The foam concrete composite wall filled with not only in durability,fire resistance performance is good,but also energy saving,environmental protection and other advantages,along with the deepening of the development of material properties,it can become a good su bstitute for the existing insulation materials,used in the construction engineering wall.Because of the large number of voids inside the foam concrete,it has low bulk density,which can be used to optimize the size of the structure in the building struc ture,so as to achieve the purpose of saving cost and material consumption.The foam concrete is a sponge like material,which can absorb the energy of the foam concrete structure under the earthquake load,and reduce the effect of earthquake damage.Therefore,the use of foam concrete structure in the construction industry can effectively improve the seismic performance of buildings and energy saving and environmental protection performance.Using the combination of experimental and finite element simu lation method in this paper and studied the bearing capacity and seismic performance of foam concrete composite wall panels,it provides the basis and theoretical guidance for the application of foam concrete composite wallboard in engineering.The main contents of this paper are as follows:1.The experiment model ratio of 1:2,test according to the displacement loading.Through the observation of each stage,from the beginning of the loading to the final destruction,the development of the cracks,the horizontal displacement and the ultimate failure characteristics of the specimens,analysis of the failure patterns,hysteretic curves obtained by experiment and calculation of energy dissipation capacity,ductility,stiffness degradation,anti shock performance of structure.2.ABAQUS software is used to simulate and analyze the foam concrete composite wall plate.Comparing the simulated cloud with the experimental phenomena and force characteristics and destructional forms of the specimens are analyzed and demonstrated.3.The paper analyzes the reasonable failure form of the foam concrete composite wall under earthquake,and puts forward the restoring force model of the wall according to the test and simulation data,In order to reasonably control the failure mechanism of foam concrete composite wall under earthquake,and improve the seismic performance,bearing capacity derived foam concrete composite wallboard from theoretical aspects.
