摘要:
法兰攻丝高强螺栓连接是一种适用于装配式钢结构的新型连接方式,具有广阔的应用前景.作者主要对其在钢结构梁柱T型连接中的受力性能进行了试验研究,考虑了T型连接翼缘板厚度和螺栓直径2种参数变化时对连接节点受力性能的影响,对10个试件进行了单向拉伸试验,观察了破坏现象,得到了相关的试验数据和结论.试验结果表明,T型连接翼缘板厚度和螺栓直径对连接节点承载能力和法兰攻丝高强螺栓受力具有显著影响.研究可为法兰攻丝高强螺栓的实际工程应用提供参考.
摘要(英文):
The tapping flange high strength bolts connection is a new form of connection that is applied to fabricated steel structure and has a broad application prospect. In this paper the experimental study was made to research on the mechanical properties of tapping flange high strength bolts in T-stub connection joints of steel structure, regarding the thickness of the T-stub flange plate and the diameter of high strength bolt as the test paramete that is influenced on its mechanical properties that is made 10 specimens on the test research under the action of one-way static loads, it is observed the damage form of all specimens,it is got the date of experiment and it came to a conclusion. The research conclusions show that the thickness of T-flange and the diameter of bolts are of important influence on the mechanical properties of T-stub connection. The research can be used as reference for the engineering application of tapping flange high strength bolts.
