Structural design of Suizhou Public Activity Center
The Suizhou Public Activity Center is a complex multi halls integrated urban public building with features such as unidirectional length,significantly asymmetric mass distribution,large-span,large overhang and large roof openings.Based on the analysis of key and difficult points,a seismic reduction structural system consisting of cast-in-place prestressed reinforced concrete frame and buckling constraint support was adopted.Buckling restrained brace was used to solve the torsion caused by plane unidirectional superlong,while forming multiple seismic defense lines in the structure.The large-span floor adopts pre-stressed ribbed floor to control the height of the structure.Specific strengthening measures have been proposed for the embedded end problem of large openings in the roof.A BRB layout and seismic reduction parameters design for this type of structure were proposed,and the seismic reduction effect of BRB was demonstrated through finite element numerical simulation analysis.Aiming at the situation of exceeding the limit,seismic performance targets and seismic measures have been proposed.
