The Studying Of Concrete Damage Model On Nonlinear Analysis Of Shear Wall Structure

With the rapid development of economy,more and more high-rise buildings have emerged in our daily lives.The reinforced concrete shear wall structure as one of a major component which be used to resistance to lateral forces of high-rise buildings.Because of its possess strong anti-lateral rigidity,and can be effectively reduce the lateral displacement,and have better anti-seismic performance,therefore,the conceret shear wall more and more be valued and widely used in the high-rise building.A growing number of scholars in our country and abroad have started to focus on the shear wall's calculation model of nonlinear analysis and research,and has made a variety of shear wall calculation model,but,there is still more or less defects and deficiencies. Therefore,we need further research and improvement.Firstly,it have a brief sketch to the shear wall calculation model of today's state of development in my paper,and have described in detail a variety of concrete damage model,especially,the damage model of ABAQUS which have model to be used.Secondly,the focus of this paper is create the plane rectangular unit with steel reinforcement which based on the plane rectangular unit to be used in numerical simulation for the shear wall,and derives its stiffness matrix.Finally,the use of large general nonlinear finite element analysis software-ABAQUS have numerical simulation for the shear wall which the proposed,and made to compare the result of analysis with the result of experiment of the shear wall structure,and fit well,so we get the conclusions that the shear wall model can better simulate the actual loading situation.At the same time,by changing the concrete strength and axial load ratio,to analyze these factors influence to the shear wall model,to obtain some useful conclusions,and we can lay a solid foundation for future research to further study.
