Steel reinforced concrete structure is one of the primary structure of the future and more high-rise building applications , weaknesses, take advantage of the respective merits of the steel and concrete structure , to achieve the purpose of full use of the materials . In multiple senior structural system , the crucial problem of node processing , generally through the calculation and construction of the measures of the joint core strengthening , to ensure the the node carrying capacity , ductility and seismic performance requirements . However, due to the characteristics of the steel reinforced concrete structure , can learn from some node in the steel structure forms , and to improve the the SRC node seismic performance and ductility , \Therefore , innovative and exploratory research dog bone SRC node has its seismic performance study also has a very important theoretical guidance and engineering practical significance . This paper studies the steel reinforced concrete frame edge node seismic performance , its low cyclic loading test using ANSYS three-dimensional nonlinear finite element analysis software for computer simulation , and to explore the dog bone steel reinforced concrete frame joints the parameters of the formula and the node design steps . Proposed by prefabricated steel reinforced concrete frame edge node static test focuses on the analysis and comparison of the common node and a dog bone node failure pattern , bearing capacity , hysteretic behavior , ductility , stiffness degradation , energy dissipation capacity , plastic hinge zone rotation and the core area of ??shear deformation and seismic performance analysis and evaluation , and force characteristics of the nodes in the core area of ??stress transfer mechanism . The results show that : ( 1 ) dog bone steel reinforced concrete frame edge node can significantly improve the seismic performance of the node , and the good performance of the force , the force transfer clear ; (2) the results of the non-linear finite element analysis using ANSYS close to the experimental value , prove that the model is reasonable ; ( 3 ) dog -bone SRC frames given node design method available for designers to reference and code revision .
