摘要
针对目前混凝土受拉应力—应变全曲线下降段获取方法不足的问题,从试件构制改进出发,提出了阻断钢筋的概念及一种新的试验方法,并通过试验获得了混凝土受拉应力应变全曲线,验证了该方法的可行性。
Aiming at the shortcomings of determining descent segment of concrete complete direct tensile stress-strain curve at present, based on improved reconstruction of concrete specimen, this paper puts forward a concept of crack re- sistance reinforcement and a new experiment method. And then the concrete complete direct tensile stress-strain curve is obtained by the experiment successfully. Finally , it proves the feasibility of this method.
