以实际工程中设有1／4环加劲肋的钢管-板节点进行足尺模型试验和有限元分析，通过改变加劲肋的宽度或厚度，得到增加加劲肋的厚度或宽度均可提高节点的极限承载力，且增加厚度比增加宽度更为有效。研究结果不仅为实际工程的建设提供了参考依据，还丰富了此类节点研究的数据库。%The full scale model experiment and finite element analysis are made for the tube-gusset joint with 1/4 circle stiffening rib in practical projects. The results indicate that the joint' s ultimate bearing capacity would be increased with the increase of the thickness or width of stiffening rib, and the increase of thickness is more efficient than the increase of width. The study reslut would not only provide bases for practical engineering construction, but also improve the database of the joint research.
