| 摘 要： | 本文采用Instron 1343型电液伺服试验机,控制应变速度,对不同品种(普通砼、陶粒砼)、不同强度的配筋及不配筋砼试件进行拉伸试验,得到了稳定而完整的砼拉伸应力-变形全曲线及其断裂能量G_F。研究了砼品种、强度、配筋等因素对受拉断裂特性的影响,并提出了砼受拉断裂的本构模型。

| Abstract: | In this paper, tension experiments of ordinary and light weight aggregate concrete specimens with different concrete strengths, with or without reinforcement were performed by using the Instron closed-loop hydraulic servo testing system.Based on this experimental study, stable and complete curves of stress-strain relationship of concrete under tension as well as the relevant fracture energy were obtained. In addition, influences of kinds of concrete as well as those of strengths and reinforcement on tensile fracture of concrete were investigated. Finally, the consti tutive modelling of tensile fracture of concrete was presented as well. |
