Abstract:This project is a reinforced concrete out-of-code high-rise building with the height of B-level required in code. There are some out-of-code items such as torsional irregularity, local transition (cross-layer column) and tower offset. Details  of seismic performance objectives of important parts were introduced, and its seismic performance analysis was carried out, and the elastic time-history analysis was used to supplement the earthquake calculation under frequent earthquake, and elastic-plastic deformation calculation under rare earthquake. The results show that the structure has good seismic performance, and can effectively meet the performance objectives of the two-stage design in seismic design.

Keywords:B-level height; tower offset; bracing transition; frame-corewall
