摘要：
In order to solve the problem that the traditional pure steel tower is easy to buckle under compression, a type of steel-concrete composite tower was proposed. In order to study the stability of the steel plate under axial compression in the steel-concrete composite tower, the monotonic axial loading test of the steel-concrete composite tower was carried out, and the failure modes and load-strain curves of the specimens were obtained. The experimental results show that the local buckling failure of the steel plate between the studs occurs in all the steel-concrete composite tower specimens. The buckling bearing capacity of the steel plate increases with the decrease of the curvature radius and the spacing-to-thickness ratio (the ratio of stud spacing to the thickness of steel plate). Based on the experimental results, the finite element (FE) model was established and its accuracy was verified. Based on the finite element parametric analysis results, the design formula of the effective length factor of the inner and outer steel plates of the steel-concrete composite tower was proposed, which can be used to calculate the critical elastic buckling stress of the inner and outer steel plates in the steel-concrete composite tower. © 2021, Editorial Office of Journal of Building Structures.
