摘　　要： 钢筋混凝土受弯构件纵向配筋率ρ的取值,现行混凝土设计规范(GB50010—2002)允许的范围是比较大的,然而在实际工程中,钢筋混凝土受弯构件内纵向配筋率ρ的大小对建筑工程质量、耐久性、经济性等方面都有很大影响。该文仅从有屈服点钢筋在钢筋混凝土梁内纵向配筋率入手,通过理论分析、经济比较,研究确定钢筋混凝土受弯构件- 梁的合理纵向配筋率。 The reinforcement ratio of longitudinal tensile steel in reinforced concrete beam has been presented a wide range in the Design Code of Concrete Structure . the value of the reinforcement ratio is connected with the factor of the construction quality and durability and economy and etc. This paper is based on reinforcement ratio of longitudinal tensile steel with yield point in flexural reinforced concrete beams, and through theoretical analysis and economic comparison , a reasonable reinforcement ratio of longitudinal tensile steel for reinforced concrete beams is presented .

关 键 词： 钢筋混凝土梁 纵向配筋率 挠度 裂缝 结构设计
