质量分布对框架错层区域剪力的影响分析
EFFECT OF MASS DISTRIBUTION ON THE SHEARING FORCE IN THE SPLIT-LEVEL REGION OF FRAME
【摘要】 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。
【Abstract】 Through the dynamic time-history analysis on the regular split-level structures as well as the symmetric trans-dimensional structures with different mass distributions under seismic waves, the effect of mass distribution on the shearing force in split-level region was analyzed. Based on the analysis, the force mechanism in split-level region of split-level structures was explained theoretically. The formulas to calculate the shearing force and the relative ratio of shearing force in the split-level region were deduced.
