摘要
根据目标地震反应谱,采用三角级数叠加法生成有效峰值和持续时间均相同,但峰值包络曲线不相同的一系列人工地震波,运用Midas Building软件对一个6层钢筋混凝土框架结构进行地震波反应弹性时程分析。计算结果表明:地震波峰值包络曲线是影响结构地震波反应的主要因素。
Firstly, according to the target, earthquake response spectra, the article generates a series of artificial seismic wave whose effective peak and duration are the same but the peak envelope curve is not the same by trigonometric series superposition method. Then, earthquake wave response elastic time-history analysis is done on a 6 story reinforced concrete frame structure by software Midas Building. The results show that the seismic wave peak envelope curve is a main influencing factor of seismic response.
