| 摘 要： | 该文利用超高韧性水泥基复合材料(UFHTCC)所具备的较好的裂缝控制能力、较高的耗能能力、耐腐蚀性以及与混凝土之间良好的粘结性能,将其浇注在混凝土三点弯曲梁的受拉面,对加固后的混凝土三点弯曲梁的断裂过程进行了研究.首先由界面变形一致的假定,忽略了UHTCC未开裂区域的弹性变形,提出了UHTCC总裂缝宽度Wu的确定方法,...

| Abstract: | Ultra High Toughness Cementitious Composites(UHTCC) can be used as reinforcement material because of its good performances on crack control,energy consumption,corrosion resistance etc.The fracture process of concrete three-point bending beams retrofitted with UHTCC on tension face was studied.Based on the assumption that the interface deformation is consistent and by neglecting the elastic deformation of uncracked regions of UHTCC,a method for determining the total crack width wu of UHTCC is proposed and a ... |
