HRB500级钢筋是目前国家主要推广的钢筋型号之一,而HRB335级钢筋是20世纪许多建筑结构主要的配筋型号。本文通过简单的单轴拉伸试验获得两者的主要的力学参数和荷载-位移全曲线,通过对比试验结果,发现HRB500级钢筋相对于HRB335级钢筋存在着更好的力学性能,能产生更好的经济效益。
HRB500 steel is currently one of the major national promotion of steel models, and HRB335 steel reinforcement is the 20th century many of the main building reinforcement structure models. In this paper, a simple uniaxial tensile test to obtain the main mechanical parameters and load-displacement of the whole curve, by comparing the test results and found HRB500 grade HRB335 grade steel has better mechanical properties, can produce better The economic benefits.
