Abstract:Abstract: Based on rational damaged plasticity constitutive model of steel and concrete, the FEM package ABAQUS was adopted to establish the fine FEM mode of super rise steel frame-R.C. core wall structure, including the geometric nonlinearity and the material nonlinearity, such as the damaged plasticity development of concrete material properties. The elastic-plastic time history analysis of the structure under rarely met earthquake was carried out in this paper. The calculated results, including damage evolution process of core-wall and floor slab, vertex displacement time-history curves, basal shear time-history curves, and floor displacement angle envelope curve and energy response law of the whole structure were attained. The results show that the maximum damage of concrete exists in the bottom of the super rise steel frame-R.C. core wall structure, and additional profile steels and reinforcing bars were suggested to be set to improve the workable ability under rarely met earthquake. It can also be seen that the elastic-plastic time history analysis can reveal the behaviour of the structural system under rare earthquake, and the method mentioned in this paper may be referred for correlative research.
