【摘要】 本文首先对在不同质量分布情况和不同地震波作用下的平层、规则错层和对称变维错层框架模型进行了动力时程分析,研究了质量分布对错层区域所受剪力的影响规律。在此基础上,对错层框架错层区域的受力进行了简化理论分析,提出了错层区域剪力及剪力相对比值的计算公式。更多还原

【Abstract】 Through the dynamic time-history analyses on the regular split-level and symmetric trans-dimensional structure with different mass distribution under seismic waves, the effect of mass distribution on the shearing force of split-level region was analyzed. Based on the analyses, the simplified theoretical explanation for the force mechanism of split-level region in split-level structure was made. Finally, the formulas to calculate the shearing force and relative ratio of the shearing force in the split-level region were deduced.更多还原
