【摘要】 文章通过空间结构微分形式的运动平衡方程与逐步积分法结合的数值方法实现了基础滑移隔震复杂层状空间建筑结构二阶效应条件下的水平正交两向、竖向、水平扭转多维耦联时程反应的求解计算;并通过编程实现了同时输入三维地震波一工程案例的计算机仿真,且输出了墙(柱)受力构件的六维(正交两向弯矩、正交两向剪力、扭矩、轴力)内力地震动态时程反应数据。工程案例的结果表明,本算法稳定可靠,可为相应的基础滑移隔震复杂空间建筑结构的多维性能分析、建筑结构设计及检测提供帮助。更多还原

【Abstract】 With balance equation of spatial structure in differential form and step-by-step integration,the two-directional level orthogonal,vertical,horizontal and torsional multi-dimensional coupling time-history response of the complex layered space building structure with sliding base isolation under the condition of second-order effect were calculated.Besides,a simulation with three dimensional seismic input was conducted with computer programming.The Six-demensional earthquake dynamic time-history response data of internal force of the stressed parts such as wall slabs and columns was also given.The results of the project cases show that the algorithm is stable and reliable,and it can be used in the analysis of multi-demensional performance,architectural structure and measurement for building structures with sliding base isolation.更多还原
