(1 西南石油大学,成都 610500; 2 四川建筑职业技术学院,德阳 618000)[摘要]在实际工程设计中,利用现行《混凝土结构设计规范》(GB50010—2002)中圆形截面受弯构件配筋计算理论公式中的超越方程常用的简化公式,其计算结果存在不可忽略的误差。采用数值拟合方法对该简化公式进行研究,得出了更科学合理的简化公式。[关键词]钢筋混凝土; 圆形截面受弯构件; 配筋计算; 多项式拟合Study on simplified method of reinforcement calculation of circularsection flexural members of reinforced concreteWu Mingjun1,2, Chen Shaoyun2(1 Southwest Petroleum University, Chengdu 610500, China; 2 Sichuan College of Architecture Technology, Deyang 618000, China)Abstract:In practical engineering design, the errors can’t be ignored in the results of the reinforcement of circular section flexural members by the commonly used simplified formula of transcendental equation, which mentioned in the Code for design of concrete structures. By fitting of the original formula, a more scentific and reasonable simplified formula was presented.Keywords:reinforced concrete; circular section flexural member; reinforcement calculation; polynomial fitting作者简介:吴明军,教授,高级工程师,Email:346116459@qq.com。参考文献[1] GB50010—2002混凝土结构设计规范[S]. 北京:中国建筑工业出版社,2002.[2] 徐建. 一、二级注册结构工程师专业考试应试题解[M].2版.北京:中国建筑工业出版社,2006.[3] 孙芳垂.一级注册结构工程师专业考试复习教程[M].3版.北京:中国建筑工业出版社,2004.
