Determination of the bond behaviour between reinforcing steel and autoclaved aerated concrete by the " beam test " - part 1 : short term test ; german version en 12269 - 1 : 2000 通过抗弯试验测定钢筋和高压蒸汽加气混凝土粘性.第1
The experiment scheme has first proposed an idea to strengthen rc beams using hybrid frp sheet , which comes from cfrp sheet and afrp sheet 其次,本文还进行了11根纤维布加固混凝土梁的抗弯试验研究,第一次采用了碳纤维布、芳纶纤维布混杂加固方案。
The results of the bearing bending experiment show that the steel plates can be combined with original beams by the construction gum , which makes the steel plates bearing bending together with original beams . at the same time the gluing steel plates enclose tensed concrete , improve the capability of resisting tension and limit the crack in the concrete 抗弯试验结果表明:由于加固钢板通过结构胶与原梁相结合形成组合构件,使钢板与原梁一起参与受弯作用;同时,所粘钢板包住受拉混凝土,改善了混凝土的抗拉性能,阻止并限制了混凝土中裂缝的发展。
3 . based on the bond test for 33 concrete specimens and gfrp and bending test for 15 beams strengthening with gfrp , surface preparation of concrete , type of epoxy adhesives , thickness of adhesives , hardening time of adhesives , cure condition after strengthening are considered , and the effect on concrete structures strengthening with gfrp causing by construction behavior was analyzed . 4 根据gfrp片材加固混凝土结构在施工中常涉及到的一些相关因素,如混凝土基层表面处理情况、所选用的粘结剂类型、涂抹粘结剂的厚度、加固的方式以及养护状况,进行了33个混凝土试件与gfrp片材的剪切粘结试验,并进行了采用gfrp片材加固的15根混凝土梁的抗弯试验,分析了与施工性能相关的因素对gfrp片材加固混凝土结构效果的影响。
