Abstract:The Building 3 of Poly International Plaza in Guiyang is an out-of-code high-rise building with a particularly irregular structural system. The load transfer between the irregular shear wall on the upper part and the large column network of the lower podium is complex, so it is necessary to set a high-level transfer layer. The wide beam transfer system is adopted in the project in order to define the load transfer path of the whole structure, alleviate the stiffness weakening caused by high-level transfer, and improve the overall seismic performance of the structure. According to the relevant specifications and technical requirements, the seismic performance of the structure was analyzed on the whole, and then the finite element software was used to conduct the detailed finite element analysis on the transfer layer and transfer beam, which were very important but relatively weak in the structure. At last, the wide beam transfer members were designed and rechecked according to relevant codes. The results show that the design of the wide beam transfer system meets the requirements of the code, which can be used as a reference for the design of transfer layer in other projects.

Keywords:Poly International Plaza in Guiyang; out-of-code high-rise building; wide beam transfer system; high-level transfer
