钢管混凝土四肢柱人字形缀杆双腹板肩梁的受力性能

Carrying behaviors of herringbone lacing double web stay member of open concrete filled steel tube with four main elements

通过模型试验与有限元分析的方法，主要探讨钢管砼四肢柱人字形缀杆双腹板肩梁的受力性能，指出采用人字形缀杆可以提高肩梁的承载力，而肩梁上、下翼缘与腹板的共同工作性能不如普通的工形截面梁。

By combining model test with finite element analysis, carrying behaviors of herringbone lacing double web stay member of concrete filled steel tube with four main elements are discussed. The result reveals that berringbone lacing bar may improve the bearing capacity of stay member, but the joint working behavior may be inferior to nomal I-section beam.
