摘要
Abstract
A headquarters building is a twisted frame-core tube structure,and the outer frame steel columns are inclined counterclockwise around the centre of the building.When bearing the vertical load,the force-bearing mode of the twisted structure is quite different from that of a conventional building structure.The vertical load is decomposed into the horizontal force and axial force along the inclined column,and the horizontal forces are combined to form the overall torque to the structure.The overall structure and members under vertical loads were analyzed.The floor slab is assumed as an elastic plate,and the P-Δ effect under gravity load is also considered,which can better reflect the actual stress of the twisted structure,with a focus on analyzing the internal force of the outer frame inclined column,the in-plane shear force of the floor.The calculation results indicate that there are significant differences in the overall and member forces under vertical loads between twisted and non-twisted structures.The shear force of the core tube wing wall under vertical load is equivalent to that under frequent earthquake action,and the shear force of the corner column is about 4～6 times of that under frequent earthquake action,which should be paid attention to in design.关键词
