引言对钢筋混凝土某些问题,有关教科书和手册建议采用叠代法计算,或利用按设定的钢筋位置所编制的图表进行分析。若不满足此项假定,则用辅助公式以提高计算精度。本文推荐的方法比较简单,可用于截面中任何位置的钢筋以及长期荷载和短期荷载的综 INTRODUCTION For certain problems with reinforced concrete, textbooks and manuals are recommended for iterative methods, or for charts based on the positions of the bars. If you do not meet this assumption, then use the auxiliary formula to improve the calculation accuracy. The method recommended in this paper is relatively simple and can be used for reinforcing bar anywhere in the section and for long-term and short-term loads
