圆形截面偏压构件正截面抗压承载力计算系数探讨

Research on Calculation Coefficient of Normal Section Compressive Bearing Capacity of Eccentric Compression Members with Circular Section

根据JTG D 62—2004《公路钢筋混凝土及预应力混凝土桥涵设计规范》,比较了圆形截面钢筋混凝土偏压构件正截面抗压承载力计算系数D的查表值与公式计算值的差异,提出了修正方法。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。

According to the code for design of highway reinforced concrete and prestressed concrete bridges and culverts,the differences of calculated value and table value on calculation coefficient D for normal section compressive bearing capacity of reinforced concrete eccentric compression members with circular section were compared.And then correction method was proposed.The analysis results show that the method has good accuracy,which meets the needs of bridge design.
