| Abstract | The inelastic response of reinforcement concrete shear panel to strong ground motion is influenced by stiffness and energy dissipation capacity. As earthquake motion excites the structure to larger displacement, its stiffness decreases and its energy dissipation capacity increases. Total energy dissipation capacity can be separated into energy dissipation by concrete and steel deformation. It is found that magnitude of energy dissipation by concrete is predominant in elastic range, but contribution of energy dissipation by steel become significant in the inelastic response. Nonlinear FEM program WCOMR (Reinforced Concrete Walls subjected to Reversed Cyclic load) is utilized to investigate the hysteretic behavior of RC shear panel and to derive the design formula for shear wall in the scheme of ductility design concept of reinforced concrete. This study is concerned with developing an design - oriented equations of equivalent stiffness coefficient and equivalent damping coefficient which describes the inelastic hysteretic behavior of RC shear wall, for the preliminary analysis and design of earthquake resistance structure. On the basis of results obtained from parametric study of Nonlinear smeared crack analysis, determine the quantitative relation between linear response analysis and inelastic hysteretic response of RC shear panel which is identified by means of equivalent stiffness, equivalent viscous damping coefficient of steel and concrete. |
