摘要:
为研究内配钢骨及加劲肋的圆钢管混凝土构件轴心受拉性能,对7个钢管混凝土试件进行了轴心受拉试验,探究不同内部构造形式对构件受拉承载力和刚度的影响.试验结果表明:内配钢骨和纵向加劲肋能有效地参与受拉作用,提高构件的受拉承载力和刚度,当试件达到极限受拉承载力时,内配钢骨亦能达到受拉屈服.与普通钢管混凝土试件相比,内配钢骨、纵向加劲肋试件的极限受拉承载力分别提高13.60%和7.82%; 同时内配钢骨和纵向加劲肋试件的承载力提高22.94%; 内配环肋对试件的极限受拉承载力影响很小,但环肋能更有效地将外荷载传递给混凝土,使混凝土均匀受力.利用有限元软件ABAQUS对试验试件进行数值模拟分析,模拟结果与试验结果吻合较好.现有规范对钢管混凝土轴心受拉构件承载力的计算偏于安全,韩林海提出的钢管混凝土轴心受拉刚度公式计算结果与试验结果吻合较好.
Abstract:
In order to study the axial tensile behavior of circular concrete-filled steel tubular(CFST)members with angles and stiffeners, the axial tension test was carried out on seven specimens to explore the effects of different internal structural forms on the tensile bearing capacity and rigidity of the members. The test results show that the internal angles and longitudinal stiffeners can effectively participate in the tensile action and improve the tensile bearing capacity and rigidity of the test specimens. When the specimens reach the ultimate tensile capacity, the internal angles can reach the tensile yield. Compared with common CFST specimen, the ultimate tensile capacity of the specimens with angles and longitudinal stiffeners is increased by 13.60% and 7.82% respectively, and the bearing capacity of the specimens with internal angles and stiffeners is increased by 22.94%. The internal ring stiffeners has little effect on the ultimate tensile capacity of the specimen, but it can transfer the external load to the inner concrete more effectively, so that the concrete is evenly tensioned. The finite element software ABAQUS is used for numerical simulation analysis of the test specimen, and the simulation results are in good agreement with the test results. The results show that the calculation of the bearing capacity of the test specimen based on the existing codes tends to be conservative, while the calculation results of the axial tensile stiffness formula proposed by Linhai Han are in good agreement with the test results.
