摘要: 试验设计制作了7根配有500 MPa细晶粒高强钢筋的钢筋混凝土梁,通过变化保护层厚度、纵筋配筋率、混凝土强度等因素,分析研究高强钢筋混凝土梁的承载力。试验结果显示:应用500 MPa细晶粒高强钢筋的混凝土梁承载力的实测结果与采用规范公式计算值比较接近,可以继续沿用现有的规范计算公式。

Abstract: Seven concrete beams with fine grain HRBF500 bars are designed and tested. By changing the thickness of protective-covering, longitudinal reinforcement ratio and the concrete strength, etc, the bearing capacity of the concrete beams is analyzed. The result shows that the measured values of the capacities of the beams with HRBF 500 bars are close to those by code formulas, so the current formulas in the code can still be used.
