Abstract: A multi-tower high-position transfer structure includes a 193.05m high residential building,a 155.9m highsecurity house and a lower 42.6m high podium. The tower transfer floors are located on the 9th floor and are partiallyframe-supported shear wall structures. The structure has irregularities such as torsional irregularity,concave and convexirregularities,sudden size mutation,and high-position transfer. The overall calculation of the structure was carried out byusing the performance-based seismic design method. The influence of high-order vibration mode on the internal force of themember and the out-of-plane bearing capacity of the wall limb of the structural system with few-shear-walls in one directionwere analyzed. The solid finite element analysis of the transfer layer was carried out to check the internal force and stressdistribution of the frame-supported beam,and the stress distribution cloud diagram of the eccentric connection of sectionsteel was given. The analysis results show that all the indexes of the structure meet the requirements of the design code,and the seismic performance can reach the set performance target C. Based on the analysis,the corresponding strengtheningmeasures were proposed in combination with the structural characteristics.

Keywords:multi-towel;high-position transfer;concave and convex irregularity;size mutation;high-order vibration mode;few-shear-walls in one direction
