Abstract
To improve the reliability of the incremental dynamic analysis, the Monte Carlo simulation technique is introduced to fully consider the uncertainties in the characteristics of earthquakes. To match the computational efficiency of Monte Carlo simulation, structural seismic responses are calculated by neural networks. To consider the failure risks under 3 safety requirements imposed on the structural seismic performance by the Chinese standard, the equivalent failure probability is employed to compare the safety of 4 different design schemes composed of high-rise frame structures. The workflow of the proposed method is demonstrated by taking the 4 design schemes as examples; good agreement is found between the failure probabilities of the entire structures and their stories with their failure states. Furthermore, the safety of these schemes is compared, and some design advice is discussed.
