| 摘 要： | 对一种新型钢筋搭接灌浆套筒节点进行了力学性能试验研究和有限元分析。共设计了9组节点试件，变化的参数包括:搭接长度和钢筋直径、套筒壁厚和套筒端部约束方式。通过试验研究得出:套筒壁厚对灌浆料的约束作用较大，壁厚不宜小于5mm；套筒端部不做处理时节点的连接效果更好。基于试验结果采用ABAQUS软件进行了有限元补充分析，通过对比验证了有限元模型各个假设和本构模型取值的合理性。本研究以期为装配式混凝土结构的钢筋连接研究提供参考。

| Abstract: | The mechanical properties and finite element analysis of a new type of reinforcing bars lap joint with grouting steel sleeve are carried out.A total of 9 sets of joint specimens were designed with the varied parameters length of the lap,the diameter and thickness of the sleeve,and the restraint at the end of the sleeve.Through the experimental research,it is concluded that the wall thickness of the sleeve has a great confinement effect on the grouting material and the wall thickness should not be less than 5 mm;the connection performance is better when the end of the sleeve is not treated.Based on the test results,the ABAQUS software is used for the supplementary analysis.The rationality of the assumptions and the constitutive model used in the finite element model is verified.This study is aim to provide reference for the researches on connections of reinforcing bars in the prefabricated concrete structures. |
