本文利用最小二乘法,求得圆形截面受弯构件配筋与受压区圆心角之间的近似关系式,避免了解规范公式中的超越方程,便于手算圆形截面受弯构件正截面承载力.
In this paper, the least squares method is used to obtain the approximate relationship between the reinforcement of the circular section and the central angle of the compression zone, so as to avoid understanding the overrunning equation in the formula and facilitate the calculation of the normal section bearing of the circular section flexural member. force.
