钢骨钢筋高强混凝土构件正截面承载力

根据塑性理论推导出钢骨的Ns-Ms相关曲线，并给出了实用的开状系数；采用累加强度法推翌出了钢筋高强混凝土的Nrc-Mrc相关曲线；将钢骨的相关曲线与钢筋高强混凝土的相关曲线相累加，建立了基于最大累加强度的钢骨钢筋高强混凝土（SRHC）构件正截面承载力的计算方法，并给出了相应的计算公式，该方法可为新规范的修订提供参考，同时可用于工程设计中。

Flexural strength of steel reinforced high-strength concrete members

The N s M s interrelated curve of steel member is deduced according to the plastic theory, and the practical shape coefficients are also given. The N rc M rc interrelated curve of reinforced high strength concrete member is deduced according to the superposed strength method. The N s M s interrelated curve and N rc M rc interrelated curve can be superposed, then the method determining the flexural strength of steel reinforced high strength concrete members is proposed, which is based on the maximum superposed strength method. The corresponding formulas are obtained in this paper. The method proposed above can give a reference to revising new norm, and also can be used in engineering design.
