| At present,China is vigorously promoting the assembled structural system,advocating the concept of green building,and developing a new wall structure that combines light weight and wall insulation protection functions will be a future development trend.The assembled hollow shear wall structure can be regarded as a typical energy-saving and cost-reducing wall.The structure forms a vertical hole by providing a bellows in the wall,so that its own weight is reduced and the wall rigidity is reduced.The earthquake is reduced to a certain extent,and the ductility is improved.In this paper,a finite element analysis of a hollow shear wall for a fabricated structure is carried out.The main work and research results include:(1)Briefly describe the development and application status of several prefabricated shear wall structures at home and abroad,and the experimental and numerical simulation research status of hollow shear wall structures,and propose a fabricated concrete hollow shear wall structure system;(2)Numerical Model of Concrete Hollow Shear Wall by Using ABAQUS Finite Element Software.The load-displacement curve,hysteresis curve and failure mode obtained from the simulation are compared with the results from the original test to verify the rationality and validity of the model;(3)The two influencing factors of axial compression ratio and aspect ratio which affect the bearing performance of the wall are changed.The bearing capacity and energy dissipation capacity of the wall under monotonic and low-cycle reciprocating loads are compared and analyzed.The research results provide a design reference for the application of fabricated hollow shear walls;(4)Taking practical engineering as an example,combining with the trend of building industrialization,the advantages of the structure system in prefabrication,mechanization and batch production are demonstrated,and the application value and Prospect of the structure system are further analyzed. |
