摘要:
从地震动功率谱密度函数和频响函数两方面对多点输入反应谱法中的关键相关系数又进行了简化.首先将H*i(ω)Hj(ω)写成实部和虚部和的形式,然后根据实部和虚部系数的特点以及频响函数对地震波的分量有很强的选择性的性质,将实部和虚部的系数分别进行简化.简化后的系数不需要再进行繁杂的积分运算,计算简单易行,节省了计算时间,并可获得满意的计算精度.
Abstract:
Based on the simplified multi-support response spectrum method,this paper presents a simplification of the correlation coefficients from the main parts of the power spectrum density function and frequency response function in this method. Separated H*i(ω)Hj(ω) into real and image segments, the real and image segment coefficients are simplified respectively according to the character of the real and image segments and the main selectivity of frequency response functions to seismic wave. The simplified method passes over the complex integral in the process of calculating the correlation coefficients, so it decreases the calculation time and is simple and accurate.
