| With the development of the age,the protection of Ecological Environment has attracted attention from people.in the ancient world wood was widely used in all kinds of construction,it has special characteristics,durability and earthquake-proof of timber structure was identified many times in history.In China the shortage of timber are serious,a new kind of environmental material is imperative.Through research of scientific personnel,according to the status of China’s forest,modern bamboo came out,modern bamboo is a new kind of material which is produced by gluing technique.After years of research,now modern bamboo is used in engineering structure including all kinds of buildings and bridges.In recent years,modern bamboo frame shear wall structure building becomes more and more popular,it can not only satisfy the demand of space but also ensure the resisting lateral deformation capability of the whole structure,in order to study seismic performance of the structure theoretically,the paper used numerical simulation method to study seismic performance of a modern bamboo frame shear wall structure.The paper referred to domestic and foreign scholars’ experience in the structure being modeled.It analysis seismic performance of the structure from two levels including the whole structure and influence factor.(1)The paper summarized the development of bamboo and wood,the development of the structure,earthquake damage,the research status of modern bamboo frame shear wall structure.(2)When analyzed dynamic behavior,according to the actual condition of research object,the frame model’s and complete model’s natural frequency and modal were calculated by using Block Lanczos,important parameters were provided for dynamic analysis,and the finite element results were compared with theoretical results.(3)By using mode-superposition response spectrum method,internal force and displacement were calculated,elastic solution and seismic response of the engineering structure were done under rarely and commonly seismic loads.Through manual calculation,the structure’s horizontal earthquake action was gotten by using the base shear method,element bearing capacity was checked,at last the results of mode-superposition response spectrum method were compared with the results of manual calculation.(4)Because of the uncertainty of seismic intensity,constitutive relation was defined in software by using information,two pieces of seismic records and one piece of artificial wave were selected in the paper,horizontal loading was applied to the structure;Seismic response of the engineering structure were done under rarely and commonly seismic loads;The differences among tree methods were found,the seismic performance of the structure was studied further.(5)Wall is the main member of lateral resistant system in the structure,the problems during the analysis were mixed,four parameters on the lateral resistant ability of the whole structure were analyzed,and the ways of improving the seismic performance were given. |
