钢筋砼双向弯曲构件的近似配筋计算

Calculation of Approximate Reinforcement of Rebar Concrete Compound Blending Component

根据钢筋砼双向受弯构件的受力特征,采用相应有假设,利用正截面承载力计算理论和应力应变关系,得出了钢筋砼构件双向受弯时,中和轴位置的确定及配筋计算方法,同时对正截面承载力的校核也提出了建议,与现有的方法比较,具有概念明确,方法简单,实用的特点。

In accordance with the stress - bearing characteristics of the compound blending component, the paper works out a method to define the place of neutral axis and calculate the reinforcement while it has compound blending. In the meantime, it also puts forward some proposals about proofrcad of the bearing capacity of normal section. Compared with the methods in existence, the new method has the following advantages： the concept is explicit and the method is simple and practical. An example shows that the method is precise enough in technical Application.
