摘要
在对多维输入和一维输入进行比较分析的基础上,建立了多维多点输入下计算杆件内力的简化公式,通过计算多维一致输入、一维一致输入和一维多点输入下的杆件内力,可由简化方法得到多维多点输入下的杆件内力,将模拟地震波的时间缩短了一半.分析表明,采用简化公式使计算过程简单易行,节省计算时间,并可获得满意的计算精度.
Based on the differences of structural response between multi-dimensional excitation and simple-dimensional excitation,a simplified method to calculate member forces under multi-dimensional and multi-support excitation is presented in this paper.After calculating the member forces under multi-dimensional excitation,simple-support excitation and multi-support excitation,the member forces under multi-dimensional and multi-support excitation through the simplified formula can be obtained.The time of simulation...
