| 摘 要： | 为了方便快捷地求解矩形及圆形截面偏心受压构件的极限弯矩,基于《公路钢筋混凝土及预应力混凝土桥涵设计规范》中给出的偏心受压构件正截面抗压承载力计算公式,推导出了矩形及圆形截面偏心受压构件极限弯矩的计算公式,并进行相应的算法理论分析。还采用了有限元程序Midas进行比较计算,分析结果表明该方法具有较好的计算精度,满足桥梁设计需要。

| Abstract: | In order to conveniently and quickly solve the ultimate bending moment of rectangle and circle-section eccentric compression members,the article deduces the calculation formula of ultimate bending moment of the rectangle and circle-section eccentric compression members based on the cross-section compression carrying capacity of eccentric compression members given in Highway Steel Reinforced Concrete and Pre-stressed Concrete Bridge Culvert Design Standard,and theoretically analyzes the relevant calculation method.The article uses the finite element program Midas to compare and calculate.The analyzing result makes clear that this method has better calculation precision and can meet the design requirement of bridge. |
