| 摘 要： | 针对钢筋混凝土高层建筑抗震时程分析输入地震波选择问题，以《建筑抗震设计规范》（GB 50011-2016）设计谱为目标谱，将满足谱匹配原则的加权调幅选波方法与国内学者建议的其它输入地震波选择方法进行了对比研究。以3栋钢筋混凝土高层建筑（15层、30层和44层）为实例，针对8度罕遇地震作用和Ⅱ类场地条件，将上述方法建议的各7条地震波输入结构进行弹塑性时程分析。以结构最大层间位移角均值沿楼层分布为比较参数。结果表明:加权调幅法可用于钢筋混凝土高层建筑抗震时程分析，可以较好地降低结构地震反应均值的离散性。在8度罕遇地震作用条件下，以不同学者建议选择的地震波为输入，高层建筑时程分析结果仍呈现出较大的不同。

| Abstract: | For understanding the effects of selecting ground motions in time-history analysis of reinforced concrete high-rise buildings, the design spectrum of "Code for Seismic Design of Buildings" (GB 50011-2016) was selected as the target spectrum, which was according to earthquake intensity VIII and Class II soil site, and a comparative study was conducted between weighted scaling method proposed by authors and other ground motion selection methods suggested by domestic scholars. Taking 3 reinforced concrete high-rise buildings (15-story, 30-story and 44-story) as design examples, the various groups of 7 records recommended by the above methods were input to the structures separately for nonlinear time-history analyses. The average values of the maximum inter-story drift ratios of the structures distributed along the structural height were taken as the parameters for comparison. The results show that the weighted scaling method can be used to the reinforced concrete high-rise buildings in time-history analysis. It can obviously reduce the variability of the maximum inter-story drift ratios of the structures. While using various methods recommended by different scholars, there are some differences for the structural responses, under the condition of earthquake intensity VIII. |
