摘  要:
采用当前常见的反应谱法对地震剪力系数进行计算,得到的结果通常较小。为此,需研究不同地震剪力系数对多层建筑结构抗震性能的影响,分析了中外有关地震剪力系数的规范,设计了三种模型,分析不同模型的弹性设计结果,发现三种模型位移角可达到1/500的规范要求,经处理后,楼层地震剪力系数都高于0.024的规范值。选择输入地震,完成抗倒塌性能比较、建筑结构位移响应分析、弹塑性时程分析。结果发现经调整达到规范的模型结构抗震性能更好。

摘  要:
The common response spectrum method is used to calculate the seismic shear coefficient, and the results are usually small. Therefore, it is necessary to study the influence of different seismic shear coefficients on the seismic performance of multi-storey building structures, analyze the codes of seismic shear coefficients at home and abroad, design three kinds of models, and analyze the elastic design results of different models. It is found that the displacement angles of the three models can reach the specification requirement of 1/500. After processing, the seismic shear coefficients of the floors are all above the standard values of 0.024. Select the input earthquake, complete the comparison of collapse resistance,the displacement response analysis of building structure, elastic-plastic time history analysis. The results show that the moduli that have been adjusted to the specifications have been adjusted. The seismic performance of the type-type structure is better.
