摘要:
引用了FFT(fast Fourier transform)技术模拟多点输入下的竖向和水平地震加速度时程,水平相干函数模型采用著名的R.S.Harichandran模型,竖向相干函数模型采用刘先明博士提出的模型.分别以多点输入法和行波法对大跨度空间网格结构的2个实际工程的水平与竖向振动进行计算,并与一致输入法的计算结果进行对比,最终在非一致输入与一致输入上结构的差异、视波速及结构跨度对这种差异的影响以及行波法的精度三方面得出了一些重要结论.
Abstract:
Horizontal and vertical acceleration ground motions are generated through FFT(fast Fourier transform)technique. The R.S.Harichandran model is used as the horizontal coherency function, and Dr. Liu’s model is used as the vertical coherency function. Two practical projects of long-span space structure are studied under multiple-support excitation and wave-passage excitation as well as simple support excitation. Finally, on the differences of structure response under non-uniform excitation and simple support excitation, the influence of apparent wave velocity and the span of the difference and the accuracy of wave passage excitation, some important conclusions are reached.
