Structural Two-Parameter Exponential Damage Model Performance Analysis under Earthquake Excitation

AbstractOn the basis of the earthquake damage assessment criteria and destroyed model, the inter-story drifts of the structure under rare earthquake are obtained through the capacity spectrum method, combining the nonlinear static analysis with the structural element's plastic hinges distribution, and the earthquake damage of structure is evaluated. In this paper the relationship between the hysteretic energy of the structure and the maximal displacement is used to get the structural hysteretic energy, which greatly improved the computational efficiency and this method has broad engineering application prospects
