咬合式钢结构全螺栓梁柱节点抗震性能研究
Study on the Seismic Performance of Occlusive Fully Bolted Beam-to-Column Joints in Steel Structures
咬合式梁柱节点作为一种新型钢结构全螺栓连接节点,能够在不增加螺栓数量的情况下提高节点的承载力,因此具有承载力高、节约材料、施工便捷等优势。对咬合式梁柱节点的抗震性能开展研究。首先,完成了0齿、4齿、6齿咬合式梁柱节点的低周反复加载试验,得到节点的破坏模式、滞回曲线、骨架曲线等,发现:与无咬合齿节点相比,有咬合齿节点的承载能力和耗能能力更高,具有更好的抗震性能。随后,利用ABAQUS软件建立了3个试件的数值计算模型,通过试验结果和数值计算结果的对比验证了数值计算模型的准确性。提出的新型咬合式梁柱节点能够改善梁柱节点的承载能力和耗能能力,弥补全螺栓节点的弊端。
The Occlusive Fully Bolted Beam-to-Column (OFBBC) joint, a novel type of fully bolted steel connection, enhances the load-bearing capacity without increasing the number of bolts, offering advantages such as high structural strength, material efficiency, and ease of construction. This study investigates the seismic performance of OFBBC joints. Low-cycle reversed loading tests were carried out on three joints with 0, 4, and 6 grooves, and their failure modes, hysteretic curves, and backbone curves were obtained. The results show that joints with grooves exhibit higher load-carrying capacity and energy dissipation ability, indicating better seismic performance compared to joints without grooves. Furthermore, numerical models of the three specimens were developed using ABAQUS and validated against experimental results. The proposed OFBBC joint improves both load-bearing and energy dissipation capacities, overcoming the drawbacks of traditional fully bolted joints.
