摘要
经济配筋率的研究对混凝土结构的经济指标具有重要的理论和实际意义,根据混凝土新规范推导出经济配筋率公式,分析了经济配筋率的影响因素,并结合具体算例对经济配筋率公式进行数值分析,结果表明:梁的配筋率在0.85%～0.95%范围内,经济效果较佳,为以后工程设计提供了参考。
Research on economical steel-concrete ratio of concrete beams has important theoretical and practical.Base on the new code for design of concrete structures,this paper derives a formula for economical steel-concrete ratio,analyzes the influencing factors of economical steel-concrete ratio,and gives a numerical analysis of the formula for economical steel concrete ratio.The result indicated that the economic effect is good as steel-concrete ratio of concrete beams is in the range from 0.85% to 0.95%,which provides references for the future engineering design.
