摘要
基于结构有限元理论,将反应位移法和反应加速度法的土层反应荷载转化为节点力施加在结构上,并编制计算程序.设定某地质条件下的典型圆形结构和矩形结构为基准模型,使用自编程序和SAP2000分别计算反应位移法和反应加速度法下的结构内力.结果表明,自编程序是正确的,并且较简便,其计算精度和SAP2000的计算结果一致.
Based on structural finite element theory, soil response was transformed into equivalent nodal force which was applied to the structures by theory deducing for response displacement method and response acceleration method, then the program was realized. The performance of the program was evaluated and compared with that of SAP2000 software through several selected benchmark numerical examples, such as circular shield tunnels and rectangle structures. It is found in the study that compared with SAP2000 software, the program is correct and simple, and its accuracy is consistent with SAP2000 software.
