剪力墙结构的布置原则

发布时间:2015-9-17 9:58:48 浏览次数:490
1、尽量在角部布置剪力墙。

2、核心筒,竖向交通处布置剪力墙。

3、在离刚心最远处要特别加强。

4、墙体尽量布置成L, T等简单形式,不要过于复杂,同时剪力墙的翼墙长度尽量大于等于翼墙厚度的3倍,以减少约束边缘构件的长度及配筋。
5、尽量减少短肢剪力墙的出现,当短肢剪力墙承受的倾覆力矩超过 30%时,即为具有较多短肢剪力墙的结构,此种结构短肢墙承受的倾覆力矩不宜超过 50%

6、墙长度不宜大于8米,避免受弯后产生大裂缝及拉断钢筋。

7、避免刚度突变,比如出屋面电梯间要适当加强,减小鞭稍效应。



1, the shear wall is decorated in Angle as far as possible.

2, core barrel, division of the vertical layout of shear wall.

3, in the most distant from just heart be especially reinforced.

4, wall to decorate L, T, and other forms of simple, don't too complicated, the shear wall at the same time the wing wall length of three times greater than or equal to the wing wall thickness as far as possible, in order to reduce the length of the edge constraint component and the reinforcement.

5, try to reduce the occurrence of short limb shear wall, when short limb shear wall under the overturning moment of more than 30%, which is with more short limb shear wall structure, the structure of short limb wall under negative moment should not be more than 50%

6, the length of the wall should not be greater than 8 m, avoid big cracks after bending and tensile reinforcement.

7, avoid stiffness mutation, such as the roof elevator to strengthen appropriately, reduce the whip effect.
