Study On Cooperative Working Performance Of SRC Frame-RC Core Wall Structure Model

At present, SRC Frame-RC core wall hybrid structures have been applied to tall buildings and super-tall buildings more and more widely in our country for its better economy, earthquake-resistance and wind resistance. But the inferior study on the structures is behind of the project practice at a certain extent, and there are many different viewpoints on seismic behavior, mechanics and deformation analysis of the structure at home and abroad. So it is necessary to further investigate the cooperative working performance of the structures. The main study contents of this paper are:First, the whole storey draft curve character of the frame-core wall structures is done; a great deal of experiments date implied that the SRC frame is in the worst state when the story drift factor is about 1/250.Second, elastic and static inelastic analysis of the classical SRC frame-RC core wall structure and its variant structures models are conducted by using the popular finite element program MIDAS/GEN, And the cooperative working performance of this hybrid structure has been studied. We get some useful conclusions, including: deformation modal, distribution of frame of the structure in the elastic and inelastic stage; influence of storey drifts and frame shear force generate by the stiffness changes of the frame and the core wall, different joint connections, different number of stories; how to adjust frame shear force appropriately; the occurrence sequence of structure member hinge; the seismic performance appraisement of the hybrid structure.In the end, we obtained that SRC Frame-RC core wall is applicable in the 8 degree earthquake-resistance areas for its better ability of earthquake-resistance.
