| At present, the reinforced concrete shear wall structure of the application and research has become more mature. However, with frame in steel reinforced concrete shear wall structure is not at home and abroad, many of the studies. Force in the actual process of shear walls with steel as a result of the coupling connection between the role of the frame with steel reinforced concrete shear wall forces and ordinary reinforced concrete shear wall forces greater differences the force of its mechanism and bearing capacity of research has important theoretical significance and the value of the works.This paper studied the frame with steel reinforced concrete shear walls in the monotonic and cyclic loads and the mechanical properties of steel, axial compression ratio, concrete strength, steel ratio, and distribution parameters on the seismic properties of the wall. The main conclusions are: the use of non-linear finite element program, through the selection of a reasonable constitutive model of concrete and steel constitutive model can be used to simulate the frame with steel reinforced concrete wall of the seismic performance; with ordinary shear walls compared to steel reinforced concrete frame with shear wall loads yield higher levels of capacity in maximum capacity reduced after the relatively slow, showing good ductility; steel frame as a result of the existence of the wall to improve the seismic performance, At the same time, the existence of beam longitudinal reinforcement buckling will not occur prematurely, in these two areas to improve, making frame with steel reinforced concrete shear wall has a good seismic performance; axial compression ratio increases, the carrying capacity with the increase, but improved With the rate of axial compression ratio increases gradually reduced the carrying capacity of the structure fell into the stage to speed up the decline in carrying capacity, reduce the limit of displacement; concrete strength increased, the structure also increase the bearing capacity, stiffness change, but the ductility and seismic structure performance deterioration is obvious; changes in the structure of the rate of structural steel with the bearing capacity, deformation capacity and ductility influence; with the greater rate of steel, the greater the stiffness of shear walls, higher capacity, more capacity decreased paragraph flat, indicating that increase the shear wall with steel reinforced concrete frame with steel rate which can improve the structure of the deformation capacity and ductility. |
