The structure adopts frame-shear wall structure system,which has the characteristics of discontinuous vertical anti-lateral force components,local discontinuity of floor slabs,and irregular torsion.In response to the irregular torsion of the project,buckling constraint supports were set up,achieving good anti torsion effects.In response to the discontinuous vertical anti-lateral force components and to achieve a high lobby,vierendeel truss has been installed on the 4th floor.Based on the design concept of "strengthening the transfer layer and its lower part,relatively weakening the upper part of the transfer layer",quantitative control indicators and internal force adjustment measures for the vierendeel truss were provided.The lower chord of the vierendeel truss adopts the design of prestressed steel reinforced concrete beams,and the calculation formulas for the bending and shear resistance of the beam were given.
