［摘要］對高層建筑一向少墻剪力墻結(jié)構(gòu)的結(jié)構(gòu)體系特點(diǎn)進(jìn)行了分析，指出了當(dāng)少墻方向的扁柱樓板框架剪力比μiwf大于0-1時，扁柱樓板框架作用較大，必須驗(yàn)算扁柱樓板框架的承載力；少墻方向的X向剪力墻一般為非矩形的復(fù)雜截面，設(shè)計(jì)時建議采用組合墻肢的設(shè)計(jì)方法；梁柱框架一般為異形柱截面，應(yīng)按異形柱設(shè)計(jì)；少墻方向的扁柱樓板框架，樓板的驗(yàn)算應(yīng)考慮水平荷載的作用；建議少墻方向的設(shè)計(jì)方法采用抗震性能化設(shè)計(jì)法。

Abstract: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.
Keywords:structural system; beam-column frame; specially shaped column; flat column slab frame; performance-based seismic design
