| 摘 要： | 反应谱的标定是抗震设计的基础工作之一,模拟退火算法是基于模拟固体退火过程而提出的多参数优化组合方法。本文提出将模拟退火算法应用于设计反应谱的标定,并概述了模拟退火算法的基本原理及特点,介绍了运用MATLAB基于模拟退火算法对反应谱进行标定的过程。检验了将模拟退火算法应用于场地相关谱标定的可行性和合理性,给出了将其应用于工程场地地震安全性评价中设计反应谱标定实例。通过检验和实例分析可以看出,基于模拟退火算法的反应谱标定方法所给出的设计反应谱谱形真实地反映了原地震反应谱的特征,较客观的反映了场地相关反应谱的峰值和周期特征。

| Abstract: | Calibration of the response spectrum is one of the basic work of seismic design,and simulated annealing algorithm is a multi-parameter optimization combination method based on simulated solid annealing process.The application of simulated annealing algorithm is proposed in this paper to the calibration of design response spectrum,the basic principles and characteristics of simulated annealing algorithm are summarized,the process of calibrating the response spectrum based on simulated annealing algorithm using MATLAB is introduced.The feasibility and rationality of applying simulated annealing algorithm to site correlation spectrum calibration are tested.An example of designing response spectrum calibration in seismic safety evaluation of engineering site is given.Through inspection and case analysis,it can be seen that the design response spectrum of the response spectrum calibration method based on simulated annealing algorithm faithfully reflects the characteristics of the original seismic response spectrum,more objectively reflects the peak and periodic characteristics of the site-related response spectrum. |
