在1974年由国家建委批准颁布试行的我国《钢筋混凝土结构设计规范TJ10—74》中,由于当时条件的限制,只列出矩形、T形、倒T形和工字形截面受弯构件刚度和裂缝的计算公式和轴心受拉构件裂缝的计算公式。对其他截面形状的受弯构件,如对均匀配筋的环形截
In 1974, China’s “Code for Design of Reinforced Concrete Structures TJ10-74” approved by the State Construction Commission, due to the constraints of the conditions at the time, only the rigidity and cracks of the rectangular members, T-shaped, inverted T-shaped, and I-section flexural members were listed. The calculation formula and the calculation formula of the axial tension member crack. For curved members with other cross-sectional shapes, such as circular sections for uniform reinforcement
