钢筋混凝土圆形截面大偏心受压构件的强度计算,一股采用多次试算的方法进行。本文根据原有的理论公式导出了截面配筋系数α函数与其他各函数之间的关系,并将α函数制成了图表,通过查表,简化了原计算方法,并且还能进行强度复核。 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。
Reinforced concrete circular cross-section of the eccentric compression component strength calculation, a method using multiple trial calculations. Based on the original theoretical formula, this paper deduces the relationship between the α function of the section reinforcement coefficient and other functions, and makes the α function into a chart. Through the look-up table, the original calculation method is simplified and the strength can be checked. 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.
