| 摘 要： | 阐述了《公路钢筋混凝土及预应力混凝土桥涵设计规范》(JTG D62-2004)、《混凝土结构设计规范》(GB 50010-2010)和AASHTO规范中关于双向偏心受压构件正截面受压承载能力的相关条文,指出了三本规范中关于双向偏心受压构件正截面受压承载能力采用轴力近似公式法的异同,并提出了目前《公路钢筋混凝土及预应力混凝土桥涵设计规范》(JTG D62-2004)中双向偏心受压构件正截面受压承载能力计算公式的修改建议。

| Abstract: | This paper analyzes the clauses related to members subjected biaxial flexure and compression in the specifications of "Code of design of concrete structures"(GB 50010-2010),"Code for design of highway reinforced concrete and prestressed concrete bridges and culverts"(JTG D62-2004)and "AASHTO LRFD Bridge Design Specifications"(4th Edition 2007) and further points out the differences and sameness in axial force approximating formula used in members subjected biaxial flexure and compression in those three specifications and raises suggestions for modification in the calculation formula for members subjected biaxial flexure and compression in the current "Code for design of highway reinforced concrete and prestressed concrete bridges and culverts"(JTG D62-2004). |
