Short - limbed wall ( slw ) is defined as the shear wall with a ratio of section depth to width ( rdw ) being 5 - 8 . usually , the section width is 200 - 250 mm , and the depth is between 1 000 and 2 500 mm 短肢剪力墻是指墻肢截面高度與厚度之比為5 8的抗震墻,通常墻厚不小于200mm ,肢長在1000 2500mm之間,它介乎于異形框架柱和一般剪力墻之間。
As is well known , the effective width depends on several factors , such as the cross - section width , the height of web , the spacing of span and so on . we can conclude that width / span ratio ( overhang width / span and central width / span ) is the governing factor of the effective width 影響箱形截面梁上翼緣有效寬度的因素很多,如上翼緣寬度、梁高、跨度以及結(jié)構(gòu)體系等,通過大量計算表明寬跨比[翼緣部分寬度、箱室部分寬度與跨度的比值]是有效寬度的控制影響因素。
The work done in this paper is mainly as follows : ( 1 ) the wide beam should intrude to the wall at some length to make the flexural stress uniform along beam section width , thus make full use of the beam ' s bearing capacity and avoid the shear failure in the concrete joint . and it also prevents stress focus and concrete crack in the local shear wall 關(guān)于寬梁與薄墻肢節(jié)點,可以得出以下幾點初步結(jié)論:寬梁應該深入墻肢一定的深度,以使寬梁截面的彎曲應力沿著梁截面寬度分布均勻,充分發(fā)揮寬梁的抗彎能力,同時避免節(jié)點區(qū)混凝土的剪切失效,也避免剪力墻的局部因為受到的應力過大而拉裂。
