混凝土拉伸应力与应变全曲线的试验研究

Experimental study on whole stress-strain curve of concrete under axial tension

通过混凝土试件静态轴向拉伸试验 ,测定了其拉伸应力与应变全曲线。试验中观察了混凝土试件的表面开裂、裂缝扩展和试件断裂的全过程 ,并给出了混凝土的弹性。

Based on the test of static tension of concrete, the variation of stress and strain was accurately measured and the whole developing process from initial appearance of cracks at the concrete surface, their expansions, to utmost fracture of specimen, was detailedly observed. The main mechanic parameters of concrete, such as elasticity, strength, strain etc., are given.
