| 摘要： | This is the second part of a two-part series on the Seismic Energy Based on Fatigue Damage Analysis of Bridge Piers. This second part deals with the determination of energy and fatigue demands on bridge columns. A smooth asymmetric degrading hysteretic model is presented, capable of accurately simulating the behavior of bridge piers. The model parameters are determined automatically by using a system identification routine integrated into a computer program OPTIMA. The program can use either real experimental data or simulated experiment results from a reversed cyclic loading Fiber Element analysis. |
