Under the action of seismic force, the bias structure of the high-rise tower analyzes the torsion in the plane of the structure to find out the variation regularity of the parameters of the structure in the distribution of stiffness and the control of torsion. The torsional stress concentration area in the plane of the structure is analyzed, The stiffness of the members is the key point in the calculation of the torsional stiffness and the torsional control. By increasing the rationality of the members in the plane distribution and optimizing the size of the structural members, the analysis results are obtained: The lateral force components are optimized, structural measures are appropriately added to enhance the structural rigidity and torsional resistance of the structure, and at the same time optimize the placement of anti-lateral force components.
