（2）Timoshenko - Gere（1961）蜿蜒彎曲的簡化模型基礎上，提出了誘導通過考慮壁板的支持效果後牆上壁線計算的力學模型。
（四）參考GBJ 50018，AISI 96兩權現有規範采用有效寬度法考慮局部屈曲後強度和非彈性屈曲應力進行修正的要求認為一些彎曲的影響及非彈性修正後立柱穩定Pn能力。
（五）MATLAB 6.1編製了計算程序WSWZ選擇典型斷麵進行計算分析。分析結果表明：考慮支承效應後牆裏牆線的能力比原來提高了1.6～1.8倍；牆線牆板連接件取間隔s = L / 8比較合理，L牆為了不跟線長度；牆板立柱壁麵方向的支承效應。
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.
