在地震区高层建筑中,采用钢筋混凝土框剪结构体系,既可获得较大使用空间,又具有良好的抗震能力。在其初步设计或施工图阶段,无论采用手算还是电算分析内力和位移,都需要先确定合适的梁柱截面和剪力墙数量。经验证明,为满足水平地震荷载作用下侧向化移的限制值,增加剪力墙数量是十分有效的。但是,如果剪力墙过多,会加大地震荷载值。所以,采用简捷方法来确定
In the high-rise buildings in the earthquake area, the reinforced concrete frame-shear structure system can not only obtain a large space for use, but also have good seismic resistance. At the stage of preliminary design or construction drawing, no matter whether the internal force and displacement are analyzed by hand or computer, it is necessary to determine the appropriate number of beam-column sections and shear walls. Experience has shown that it is very effective to increase the number of shear walls in order to meet the limit of lateral displacement under horizontal seismic loading. However, if the shear wall is too much, it will increase the seismic load value. So, use a simple method to determine
