摘要：对4组共8个不同内部构造形式的钢管混凝土试件进行了偏心受压试验。结果表明：各组试件的破坏模式均为试件整体弯曲，偏压侧钢管局部鼓曲。内配纵向加劲肋减缓了钢管的局部鼓曲。与普通钢管混凝土试件相比，内配纵向加劲肋试件的极限承载力提高3.80%,内配格构式钢骨试件的极限承载力提高8.28%,同时配置纵向加劲肋和格构式钢骨试件的极限承载力提高14.33%。利用有限元软件对内配格构式钢骨-钢管混凝土构件进行偏心受压数值模拟，分析了构件的受力机理和各部件的应力发展过程，研究了混凝土强度、钢管强度、钢管径厚比、钢骨强度、钢骨尺寸以及荷载偏心距对其承载性能的影响。提出了内配格构式钢骨-钢管混凝土构件的偏压承载力计算公式，公式计算结果与试验结果吻合较好。

Experimental study on eccentrically compression behaviour of concrete-filled steel tubular members with reinforcing lattice angles
Abstract: The eccentric compression tests of 4 sets concrete-filled steel tubular(CFST) specimens with different internal details of the longitudinal stiffeners and lattice steels were carried out. The results show that the failure pattern of all specimens are overall instability accompanied by local buckling of the steel tube. For the specimens with longitudinal stiffeners, local buckling of steel tube buckling are reduced. The ultimate load bearing capacity of the specimen with longitudinal stiffeners, reinforcing lattice angles and both longitudinal stiffeners and reinforcing lattice angles increases by 3.80%, 8.28% and 14.33%. The numerical simulation analysis of eccentric compression was carried out on the CFST with reinforcing lattice angles, and the force mechanism of the member and the stress development process of each component were obtained. The influence of concrete strength, steel tube strength, tube diameter-thickness ratio, lattice angles steel strength, lattice angles size and load eccentricity on its load-bearing performance was obtained. The formula for calculating the eccentric bearing capacity of the CFST member with reinforcing lattice angles was proposed. The calculation results of the formula are in good agreement with the test results.
