摘要
通过试验研究碳纤维布加强铝合金焊接节点区的力学性能,探讨这一加强方式的可行性。试验包括1组未加强试件和4组加强后试件。比较不同加强模式下试件的破坏模式及节点刚度、极限承载力等参数,分析不同加强构造的有效性。结合试验结果认为:碳纤维布是一种有效的加强铝合金焊接梁柱节点的方式,合理的锚固措施、受拉翼缘侧采用更厚的碳纤维布等都有助于提高加强后试件的承载力。
The experimental research was carried out on the mechanical performance of welded aluminum alloy beam- column connections strengthened with CFRP. The paper also discussed the feasibility of this strengthening method. The experiments consist of a set of welded group and four sets of strengthened groups specimens. The failure mode, joint stiffness and ultimate bearing capacity of the specimens of different strengthening mode were investigated by comparison. And the effectiveness of different strengthening configurations was analyzed. Bonded CFRP was considered as an effective method to improve the bearing capacity of the welded aluminum alloy beam-column connections. Effective anchoring method, thicker CFRP on the tensile flange would improve the bearing capacity.
