Abstract:A complex unsymmetrical twin-tower high-rise building was discussed. Through concept design and analysis, structural form selection, seismic fortification measures and performance-based seismic design method were introduced. The floor stress at the connection and the bearing capacity of the simple joints were also analyzed by FEA under earthquakes. The buckling analysis for the cross-pillar and comfort degree analysis for the connection floor were introduced. The weak zones identified by shaking table test were strengthened.
Keywords:unsymmetrical twin-tower; performance-based seismic design; seismic fortification measure
