摘要
本文较为系统地给出了线性多自由度结构系统不等时间步长地震反应数值计算单步法和两步法共六种求解状态的解析递推格式,并且讨论了该算法的某些数值分析特性。本文算法计算精度高,可以求解非正交阻尼问题,是无条件稳定的算法,且满足收敛性要求。
The analytical recursion schemes of the single and two step method with six kinds of solving state for computing numerical aseismic structure response of unequal time interval of MDOF system in linear cases, are more systematically derived in the paper. Some numerical analysis characteristics of the algorithm are discussed. The algorithm is accurater. And the non-orthogonal damping problem may be solved. It is proved that the algorithm is unconditionally stable and convergent.
