配HRBF500级钢筋混凝土梁受弯承载力试验

Experimental Investigation of Flexure Capacity of Concrete Beam HRBF500 Bar

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.试验结果表明,应用了500 MPa细晶粒高强钢筋的混凝土梁承载力的实测结果与计算值比较接近,可以继续沿用现有的规范计算模式.

Abstract: This experiment designs seven fine Grain concrete beams HRBF500 bar.By changing the thickness of protective-covering,longitudinal reinforcement ratio,the intension of concrete etc,the experiment analyzes the flexure capacity of the concrete beams.The result shows that the measure value of flexure capacity of HRBF 500 bar is close to the experiment value,and it suggestes that the primary calculate mode be continued to be adopted.
