摘要
为研究纤维编织网与混凝土基体界面粘结性能,配制了与纤维编织网性能相适应的高性能混凝土,并采用德国斯图加特大学提出的拉拔试验方法,对纤维编织网增强混凝土薄板中纤维束与混凝土进行粘结性能试验,试验表明,对纤维编织网浸胶和对纤维束施加预应力后,能明显改善混凝土与纤维编织网之间的界面粘结性能,同时根据试验结果,提出了简化的粘结滑移三线段本构模型。
To measure the bonding performance of textile in composite concrete sheets, first, prepared the high performance concrete to match fiber textile, then the pulling test method from Stuttgart university of Germany was introduced and applied, and carried the bonding performance of fiber textile reinforced concrete sheets. The results of the experiments show that the fiber textile impregnating and prestressing can improve the bonding performance between fiber textile and concrete, at the same time. Based on the experiment results, proposed a simplified three segments of the bond-slip constitutive model.
