A Self-thermal Insulation Porous Masonry Wall On Seismic Performance Test And Finite Element Method Analysis

With the progress of modern society,people raise awareness of environmental protection requirements and standards of living. Energy-saving building materials has been widely appreciated. Study on New of self-insulation wall materials have been paid much attention nowadays. The porous concrete blocks with thermal insulation are able to meet the seismic requirements in reality and The load-bearing layer,the protective layer can work with each other possess very important practical significance.On the basis of summarizing the academic research,thisarticle designs four pieces of Full-sized wall,According to different simulation object the Four can be divided into Wall without opening exerted by three layer of vertical load and holed Wall,Wall without opening exerted by six layer of vertical load and Holed Wall.Based on the experimental study of Low Cyclic repeated Loading,this article conducts an earthquake resistant test on the four pieces of full-sized wall.Through analyzing the hysteretic curve,skeletoncurve,stiffness-degradation curve,ductility,energy dissipation of the four pieces of wall.We can get bigger vertical load which can strenghten therigidity of the walls, enlarge its ability of energy dissipation,but it makes the wall have great brittleness and reducesductility of the wall. The window openings decreases therigidity of the walls.The ability of energy dissipation is also to be weakened,but the plastic deformation capacity and rigidity of the walls increase.Wall computational finite element model are given in this thesis by using Abaqussoftware.IntegratedModel,ConcreteDamage Plasticity Model are adopted in the process of model building.Constitutive relation of concrete makes reference to the’Concrete Structure Design Code’.Constitutive Relation of Reinforced Concrete makes use of Yang weiZhongModel,Constitutivetensive relation bases on aConstitutional Model for Concrete materials under tensiveloading,steel bar selects ideal Elastoplastic Simulation.Analyzing and verifying the reliability of Finite Element Model through the method of single-push loading,which lay a fundation for the following parametric analysis.
