Method for calculating initial rigidity of sandwich wallboard
The invention belongs to the field of fabricated concrete structures, and particularly relates to a method for calculating the initial rigidity of a sandwich wallboard. The sandwich wallboard comprises an outer vane board, an inner vane board and a sandwich layer arranged between the outer vane board and the inner vane board, and the outer vane board and the inner vane board are made of concrete loaded with reinforcing steel bars. The method comprises the following steps that S1, the reinforcing steel bars in the outer vane board and the inner vane board are converted into equivalent concrete;S2, the height x of a pressed area of the outer vane board and the height x of a pressed area of the inner vane board are obtained; S3, the equivalent inertia moment I of the outer vane board and the equivalent inertia moment I of the inner vane board are obtained; and S4, the initial rigidity of the sandwich wallboard is obtained through the following formula, whereinthe initial rigidity is equal to E I+E I. The method has the beneficial effects that the method for calculating the initial rigidity of the sandwich wallboard is provided, the initial rigidity of the sandwich wallboard is obtained through theoretical calculation, and a theoretical basis is provided for subsequent calculation of a fabricated structure.
本发明属于装配式混凝土结构领域，具体涉及一种三明治墙板初始刚度的计算方法，所述三明治墙板包括外叶板、内叶板以及设置在外叶板、内叶板之间的夹芯层，所述外叶板、内叶板均由装载有钢筋的混凝土制成，包括如下步骤：S1、将外叶板、内叶板中的钢筋换算成等效的混凝土；S2、获得外页板的受压区高度x、内页板的受压区高度x；S3、获得外叶板的等效惯性矩I、内叶板的等效惯性矩I；S4、通过如下公式获得三明治墙板的初始刚度，初始刚度＝EI+EI。本发明的有益效果是：本发明提出了一种三明治墙板抗弯刚度的计算方法，通过理论计算得到了三明治墙板的初始刚度，为装配式结构的后续计算提供了理论的依据。
