摘要:
差分进化是一种解决多参数优化的算法,可在给定的参数范围内寻求最优值的组合,并具有快速收敛的优点。本文利用差分进化来标定设计反应谱,给出了第一拐点周期、特征周期、平台值、衰减指数等表征设计反应谱特征的参数。利用汶川地震的强震记录,对比分析了4种标定方法给出的特征参数值和计算精度。从结果看,差分进化算法标定的结果更符合实际反应谱。
Abstract:
Differential evolution (DE) is a powerful evolutionary algorithm for solution of multi-parameter optimization.It can provide the optimal parameter combination with fast rate of convergence. This paper applies DE to calibrate seismic design response spectrum to provide characteristic parameters of seismic response spectra such as the first turning point of spectrum, characteristic period, the flat height of spectrum and the attenuation index. With the strong ground motion records of Wenchuan Earthquake,the accuracy of characteristic parameters obtained with four methods is compared. The results show that response spectrum calibrated with differential evolution fits the original response spectrum best.
