轻钢龙骨复合墙体抗剪承载力计算

轻钢龙骨复合墙体抗剪承载能力是轻钢龙骨体系建筑设计的关键参数。轻钢龙骨复合墙体由结构罩面板通过自攻螺钉与龙骨相连构成,其抗剪承载力与钢龙骨、结构板、自攻螺钉均有关系,影响因素较多,主要依赖试验确定,计算理论尚不成熟。本文借鉴木龙骨墙体抗剪承载力的确定方法,推导了轻钢龙骨复合墙体抗剪承载力的计算公式,并与试验结果进行了比较。结果表明,所推出的公式是合理可信的,可用于轻钢龙骨体系建筑中复合墙体的抗剪承载力计算。

Calculation of Shear Strength of Light-gauge Steel Framed Composite Walls

In the design of light-gauge steel framed structures,one of the key parameters is the shear strength of the composite walls.Since the shear strength of light-gauge steel framed composite walls,with sheathing attached by screws,relates to many factors such as steel members,sheathing panels and screws,which are strongly dependent upon experiments,and satisfactory computational method has not been yet available.The formulas for the analysis of light-gauge steel framed shear walls are presented in this paper by using,with some modification,the method of determining shear strength of wood shear walls.The computation results agree well with the test results.Therefore,the formulas are applicable and can be used to estimate the shear capacity of light-gauge steel framed walls.
