| Abstract: | The Tower project is an ultra highrise building, it has 52 stories and a height of 189.4 meters. The main features of the structural design are as follows:1. Steel reinforced concrete structure (SRC) and tube in tube structural system have been adopted in this project as required by the project owner.2. Bored piles in 68 meters ultralong is firstly used in the loess area.3. Unbonded prestressed concrete floor slabs are used from 7th to 48th floor to reduce the total height of the building.4. Sophisticated three dimensional nonlinear analyses, including pushover analysis, dynamic response, time history analysis, are decided to precisely evaluate the seismic behavior and safety of the building. |
