| 摘 要： | 混凝土结构非杆系的二维结构或构件的配筋计算是混凝土结构配筋计算的重要部分,对于腹部均匀配筋的偏心受压构件,规范算法过于简化。针对此点,采用曲线拟合的方法来简化公式,拟合中考虑钢筋等级对相对受压区高度的影响,并通过算例进行比较,计算结果理想。

| Abstract: | The calculation of rebar extent for concrete non-linear two-dimensional structures or members is important part for calculation of rebar amount in concrete structures. But the calculation method of criterion for eccentric compression components which rebar matches evenly in abdomen is too simplified. Accordingly, considering the influence of rebar grade on relative height of compression zone, calculation methods are simplified by using the method of least square conic fitting, and the results are satisfying by comparison of some examples. |
