Abstract:Yunda Central Plaza is a large-scale commercial complex. The main tower is a tube-in-tube over-limit high-risestructure. The structural layout of the standard floor was introduced, and the analysis was carried out under the action ofsmall earthquakes, medium earthquakes and rare earthquakes. The results show that the overall structure can meet therequirements of the performance objective C. The structure of the local transfer truss joints of the peripheral frame columnswas described in detail, and the details of the transfer truss joints were analyzed by finite element analysis using the internalforce under the action of rare earthquakes. The results show that the transfer truss joints can meet the bearing capacityrequirements under the action of rare earthquakes. The middle podium has a large-span heavy-load roof, which adopts steeltrusses. The layout and selection of the roof were described in detail, and the details of the truss connection joints werecarried out by finite element analysis. The results show that the selection of roof structure and joint details are reasonableand can meet the stress requirements.
Keywords:over-limit high-rise building; local truss transfer; large-span heavy-load roof; steel truss; joint analysis
