框架结构楼梯间四角是否一定要设柱呢?从规范那里可以查到相关的规定,谢谢!

与抗震有关
你所言的柱是构造柱还是**?

我说得是框架柱,有两个角不设框架柱设构造柱可以吗?

可以啊

不一定。但要注意加强构造,如半平台处形成短柱、楼板大开洞加强梁腰筋及相关楼板等。
但若因建筑布置导致框架梁拉不通,则最好设柱。

有加的必要

构造柱要单独设基础还是直接插在砖墙上

砌体结构抗震要求楼梯间四叫加构柱 楼梯间柱 容易形成短柱
楼梯有支撑 不用必须加承重柱

框架结构楼梯一般采用板式楼梯,休息平台处的梯梁需要有柱支撑(也有做吊柱的),此柱子为梁上起柱,不应按构造柱设计,应按普通混凝土柱设计,截面不小于250x300,7度区抗震等级按三级,至于楼梯间四角设构造柱是对砌体结构而言
