对于两端固定的框架柱而言，其所受弯矩如图)所示。从图中可以看出，柱脚处所受弯矩较大。在实际施工中，无论是模板支设，还是混凝土浇筑，此处都是个薄弱环节。以前我单位柱脚处模板的支设有两种方法：方法一如图#所示，1$!!高混凝土需浇筑两次，费时费力；方法二如图’所示，
For both ends of the fixed frame column, its bending moment shown in Figure. It can be seen from the figure that the bending moment at the column foot is larger. In the actual construction, whether it is template support, or pouring concrete, here is a weak link. In the past, there were two ways to support the template at the column of the unit: Method 1 As shown in Fig. 1, the high concrete needs to be poured twice, which takes a lot of time and effort. Method 2 As shown in the figure,
