某高层建筑框架—剪力墙结构框架部分地震剪力的分析

摘要

Based on a practical tall frame-wall structure with torsion irregularity, dynamic properties and rules of the seismic shear force resisted by the frame-part of any story are analyzed. The results show that the seismic shear forces resisted by the frame-part of most stories have the relatively stable value, but several stories have the evidently variation value, and on the whole the seismic shear force of frame-columns of any story is in the same level as the seismic moment of frame-beams. From the rationality of structure design and the seismic design concept of strong columns and weak beams, the advice is that the adjustment of seismic interior force of frame-beam may be properly decreased, and the relevant adjusting method is presented.%对含扭转不规则的某高层建筑框架—剪力墙结构的动力特性、框架部分分配地震剪力规律的分析,结果表明,多数楼层框架部分分配的地震剪力有一个相对稳定的数值,但少数楼层框架部分分配的地震剪力变化幅度较大,各层框架柱与框架梁分配的剪力、弯矩基本上在同一数量级上.从结构设计的合理性以及“强柱弱梁”的抗震概念设计考虑,建议框架梁地震内力调整可适当放松,并给出相应的调整方法.
