摘要
国内外各类抗震设计规范对设计反应谱给出了不同的计算方法,通过对各类反应谱的计算方法进行对比分析;同时利用世界范围内大地震时获得的数字强震仪记录,计算出相应的加速度反应谱;结合结构动力学理论分析及统计分析方法,提出了设计反应谱统一计算公式,对开展桥梁工程的抗震分析和设计具有参考价值。
Various domestic and foreign seismic design codes give different calculation methods on the design response spectrum.This paper makes a contrastive analysis of the different calculation methods for various types of response spectrum;and the corresponding acceleration response spectrum of the digital strong motion earthquake records obtained in the world range is calculated;and combined with the structural dynamics analysis and statistical analysis method,the unified calculation method of the design response spectrum is proposed.Finally,research achievements is proved to be a reference for the analysis and design of bridge seismic engineering.
