Experimental Investigation of Flexure Capacity of Concrete Beam HRBF500 Bar

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.
