(1)提出了考虑壁板的支持效果后,他家的墙里墙线理论计算方法。
(2)Timoshenko - Gere(1961)蜿蜒弯曲的简化模型基础上,提出了诱导通过考虑壁板的支持效果后墙上壁线计算的力学模型。
(三)解释方法诱导写出四种典型边界条件下,壁线的弯曲的临界载荷。一旦固定,有对简支边界条件,变形不简单的周期函数形式表示的MATLAB필자는6.1 MSEWZ编制了程序,通过判断确定什么合理的变形函数。
(四)参考GBJ 50018,AISI 96两权现有规范采用有效宽度法考虑局部屈曲后强度和非弹性屈曲应力进行修正的要求认为一些弯曲的影响及非弹性修正后立柱稳定Pn能力。
(五)MATLAB 6.1编制了计算程序WSWZ选择典型断面进行计算分析。分析结果表明:考虑支承效应后墙里墙线的能力比原来提高了1.6~1.8倍;墙线墙板连接件取间隔s = L / 8比较合理,L墙为了不跟线长度;墙板立柱壁面方向的支承效应。
Bending thermal thin take no ban, lower profile system of wall building load-bearing structure system vertical the wall by secret column (usually a lipped channel) wall materials (for example, gypsum board, steering wheel) composed of wall. Materials not only in the wall of the building, but also to provide effective support for the column. This paper mainly considers this effect, and the performance of the port corresponding to the column affects the theoretical calculation method of the system hard wall.
Main contents include:
(1) the theoretical calculation method of the wall in the wall after considering the support effect of the wall panel is proposed.
(2) based on the simplified model of Gere - Timoshenko (1961), a mechanical model for the wall line calculation was proposed, which was induced by considering the support effect of the wall.
(three) explain the method of inducing the four typical boundary conditions, the critical load of the curved line. Once fixed, with the simply supported boundary conditions, 6.1 deformation is not a simple periodic function is represented in the form of MATLAB MSEWZ program, by judging determine what a reasonable deformation function.
(4) the reference GBJ 50018, AISI 96 in existing norms by effective width method considering the local buckling strength and non elastic buckling stress of modified requirements that revised some bending effects and non elastic stability column of PN capacity.
(five) MATLAB 6.1 has compiled the calculation program WSWZ to select the typical section to carry on the computation analysis. Analysis results show that: after considering the supporting effect of wall wall line ability than the original raise 1.6 ~ 1.8 times; wall line wallboard connecting pieces interval s = L / 8 more reasonable, l wall in order not to with line length; wall column direction of wall supporting effect.
