一向少墙高层剪力墙结构抗震设计计算方法

Seismic design and calculation methods of high-rise shear wall structure with few shear walls in one direction

对高层建筑一向少墙剪力墙结构的结构体系特点进行了分析,指出了当少墙方向的扁柱楼板框架剪力比μiwf大于0.1时,扁柱楼板框架作用较大,必须验算扁柱楼板框架的承载力;少墙方向的X向剪力墙一般为非矩形的复杂截面,设计时建议采用组合墙肢的设计方法;梁柱框架一般为异形柱截面,应按异形柱设计;少墙方向的扁柱楼板框架,楼板的验算应考虑水平荷载的作用;建议少墙方向的设计方法采用抗震性能化设计法。

The characteristics of the shear wall structural system of a high-rise building with few shear walls in one direction were studied. It was pointed out that if the shear ratio μiwf of the flat column-slab frame with few shear walls in one direction exceeds 0.1, flat column slab frame undertook large loads and the bearing capacity of the frame should be checked and calculated;the X-direction shear wall in the direction of few walls generally had non-rectangular complex sections, so it was suggested to adopt the design method of composite wall limb in the design;the beam column frame generally had special-shaped column sections, so it should be designed according to the special-shaped column;the effect of horizontal load should be considered in the calculation of bearing capacity of floor of the flat column-slab frame in the direction of few walls;the design method of performance-based seismic design should be used for the flat column-slab frame in the direction of few walls.
