环形截面钢筋混凝土受弯构件的强度计算,一般采用多次试算的方法进行。本文根据原有的理论计算公式导出了截面配筋系数β函数与其他各函数之间的关系,并将β函数值制成了图表,通过查表,简化了原计算方法。 本文还通过算例论证了这种计算方法的计算精度,在工程实践中,认为较原计算方法简便、迅速、准确。
The strength calculation of flexural members with annular cross-section reinforced concrete generally adopts the method of multiple trial calculations. In this paper, the relationship between the β function of the section reinforcement coefficient and other functions is deduced according to the original theoretical calculation formula, and the β function value is made into a chart. By looking up the table, the original calculation method is simplified. This paper also demonstrates the calculation precision of this calculation method through examples. In engineering practice, it is considered that the calculation method is simpler, faster and more accurate than the original calculation method.
