【摘要】 我国规范规定的剪重比指标常常被视为评价结构布置是否合理的重要指标之一。先对影响剪重比的各种因素进行对比分析,再结合工程实例相互验证,得出了场地类别对超限高层建筑剪重比具有重要影响,进而得出剪重比作为衡量结构布置合理性指标的不足。当剪重比不能满足要求时,若结构性能方面无严重缺陷,一般建议直接放大地震剪力即可,无须重新调整结构的布置。更多还原

【Abstract】 The shear-to-weight ratio index specified by China’s regulations is often regarded as one of the important indicators for evaluating whether the structural arrangement is reasonable.The various factors affecting the shear-toweight ratio were compared and analyzed,and then combined with the engineering examples to verify that the site category had an important influence on the shear-weight ratio of over-limit high-rise buildings,and then the shearweight ratio was used as a measure of structural arrangement.When the shear-to-weight ratio cannot meet the requirements,if there is no serious defect in the structural performance,it is generally recommended to directly enlarge the seismic shear force without re-adjusting the structural arrangement.更多还原
