Abstract: The ground structure of south distric hotel of Jinghu Meishan Plaza adopts the two-way high-level connected frame-support structure system. The structure is complex, There are five general irregular items, including irregular concave convex, discontinuous floor, irregular vertical stiffness, discontinuous vertical members and sudden change of bearing capacity, and two medium irregular items, including large torsion and small floor stiffness. The key technical problems and solutions in the structural design process of south district hotel were analyzed. Reasonable performance target was put forward based on the principle of seismic performance-based design. The overall analysis of the elastic of small earthquakes, the elastic-plastic time history of the rare earthquakes, the progressive collapse, the construction simulation and the comfort degree were carried out. The structural transformation truss, the supporting transfer truss frame column, the floor stress and the key nodes were analyzed. Through multinomial analysis，it is proved that the structure can achieve the established goal of seismic performance.
Keywords:frame-support structure system； two-way high-level connected structure； transfer truss; resistance to continuous collapse; construction simulation
