Calculation of Seismic Energy Dissipation and Optimal Analysis for a New Type of Energy Dissipation Shear Walls

Two methods are proposed to derive seismic energy dissipation formulas for a new type of energy dissipation shear walls in this paper. Combined with time history analysis, the seismic energy dissipated is calculated for an energy dissipation shear wall structure model. Then, based on the dual damage criterion of foe first exceeding the maximum response and the plastic accumulative damage, the optimal analysis is done for the design parameter of the energy dissipation devices. At last, an calculating example is provided, which indicates that the stiffness and the strength of the energy dissipation devices must be moderate in other to get the optimal seismic control for this type of shear walls.
