Steel box-concrete filled steel tube (BCFST) composite tower is a new type of tower structure proposed to be used in super-span suspension bridges. BCFST comprises of four concrete-filled steel tube (CFST) columns inside and a steel box outside. CFSTs and the steel box are connected with each other by steel webs and diaphragm plates. In this study, the combined compressive and bending loading experiments of the BCFST were conducted, and the ability of the composite tower section to deform together was studied. The experiment showed that the bottom section of the composite tower deviated from the plane section after deformation, and the other sections approximately maintained the plane section after deformation. The calculation method of the compression-bending capacity of the composite cable tower was proposed, which can provide a reference for the application of the composite tower in practical engineering. |
