摘要
利用动态样条加权残数法对网架结构的竖向地震反应进行了分析 ,运用子域法将时间域均匀分成若干段 ,得出关于试函数广义参数的递推公式、求得节点位移显式 ,进而求得杆件地震内力。编制了相应的程序 ,并对一系列标准网架进行了对比分析 ,结果表明 ,该法精度高 ,效果好。
In this paper the vertical seismic responses of latticed frame is analyzed by using dynamic spline weighted residual method. The displacements of joints through the recurrence formula about generalized parameters of trial function are given and then the seismic internal forces of structure are calculated.It is improved that the method has higher accuracy but uses less time through compiling the computation program and analyzing comparatively a series of standard truss structures.
