冷彎型鋼低層住宅房屋體係牆體立柱的性能研究

發布時間:2016-1-19 15:31:30 瀏覽次數:1306
   彎熱脹薄取之無禁,型材下層家體係的牆房屋的承重結構體係豎向那壁一般by秘密專欄(一般為卷邊槽鋼)牆圍護材料(例如,石膏板,方向盤)組成的牆。材料不僅在建築的牆壁,同時也能提供有效的柱支承作用。本文主要考慮這種效果,端口對應立柱性能影響了係統硬家牆上壁線理論計算方法設計參考。

主要內容包括:


(1)提出了考慮壁板的支持效果後,他家的牆裏牆線理論計算方法。


(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。


(三)解釋方法誘導寫出四種典型邊界條件下,壁線的彎曲的臨界載荷。一旦固定,有對簡支邊界條件,變形不簡單的周期函數形式表示的MATLAB필자는6.1 MSEWZ編製了程序,通過判斷確定什麽合理的變形函數。


(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.
