| 摘 要： | 腹板开孔轻钢龙骨作为一种有效的节能构件而被广泛应用于寒冷地区的轻钢龙骨复合住宅体系中.采用ANSYS非线性有限元方法系统分析了在轴压、弯矩、压弯基本荷载作用下,腹板开孔对标准轻钢龙骨的屈曲模式、变形、截面应力、承载力等方面力学性能的影响规律,给出龙骨腹板孔洞的合理取值范围.结果表明,常用孔洞参数范围内腹板开孔对龙骨承载力的降低幅度可以控制在10%以内;腹板开孔后龙骨整体变形能力降低,峰值应变相应减小,使龙骨的初始刚度略微增大.腹板孔洞长度是影响龙骨力学性能的重要参数,随孔洞长度增加,龙骨承载力下降,延性变差.

| Abstract: | As an effective energy saving member,the slotted steel studs in web plate have been widely used in the light gauge steel framing assembly housing systems of cold area.By using the ANSYS nonlinear finite element analysis program,the mechanical behavior rules including the buckling modes,deformation,section stress and bearing capacity of the slotted studs were analyzed systematically under compression,bending or compression-bending loads.The reasonable web slot parameter value is proposed.The analysis indicat... |
