薄壁钢-混凝土组合墙板的剪切屈曲分析
|
摘要
研究了设置自攻螺钉连接件的薄壁钢-混凝土组合墙板中钢面板的受剪屈曲问题。栓钉的设置有效抑制了钢板过早发生局部屈曲,提高了组合板的承载能力。提出新的位移函数,利用能量法分析钢面板的受剪屈曲,分析了屈曲系数随栓钉间距变化的规律。针对板件的不同使用功能要求,给出了各种厚度板件的栓钉间距限值,供设计参考。
The shear buckling of steel skin in thin-walled-steel-concrete composite wall with studs is analyzed.Through setting studs,the premature local buckling of steel skin is effectively inhibited,and the carrying capacity of composite wall is well improved.By proposing new deformation functions,the buckling of steel skin under pure shear load is analyzed using energy method.And the relation curves of buckling coefficient and stud spacing are obtained. According to different functional requirements,the stud spacing limits of various plate thickness are given for reference.
