【摘要】 本文把文献[1,5]中矩形、T形和I形截面的钢筋混凝土构件最大裂缝宽度计算公式推广到大偏心受压和受弯的环形、圆形截面构件,并推导了该公式中在使用荷载作用下的计算压力角和钢筋应力σ_δ的简化公式。 本文建议的公式曾用国内大量试验资料作了验证。更多还原

【Abstract】 In this paper, the formulas for calculating maximum crack width of reinforced concrete members with rectangular section, T-Section and Ⅰ-Section presented in the references [1, 5] have been developed to calculate members with ring and circular cross section subjected to eccentric compression and bending. Simplified expressions for calculating stress of reinforcement a and pressure angle φ under working load in the above-mentioned formulas are derived and discussed.The proposed formulas have been verified by the test data worked out in China.更多还原
