摘　　要：剪跨比是决定异形截面柱截面特性的主要因素。当剪跨比较大时 ,截面正应变分布符合平截面假定 ,随着剪跨比的减小应变分布向曲面方向发展 ,异形柱的受力性能越来越接近短肢剪力墙。Shear-span ratio is the main factor that determinat es the char acteristic of the sections of special-shaped columns. The longitudinal strain d istribution accords with the assumption of plane section when the shear-span ra tio is high. When the shear-span ratio is low ,however, they no longer remain p lane and the behavior of special-shaped column will change and approach to that of short shear-walls.
