Abstract: An office building apartment project is a 187. 2m high connected building with two towers with the same functionarranged symmetrically. The connectors are single?layer corridors with a 39. 5m span, located on the 10th, 19th, and 28thfloors. It has the characteristics of weak connection stiffness and large vertical spacing. From the analysis of the connectionform, the system of the connected structure , the seismic performance of connector and the overall structure, the stress ofthe connecting node, the comfort level, the temperature stress, etc., the following conclusions show that: the rigidconnection in this project can better meet the requirements of the building function and building façade, the connectedstructure adopts the X?direction main steel beam with horizontal support + steel truss floor deck system. Connector withweak stiffness has little influence on the dynamic characteristics of the tower. The rigid connection between the weakconnector and the tower can reduce the internal force of the connector component, which can reduce the section size andreduce the construction difficulty. The temperature stress change of each connected layer is basically the same, and theinternal force of temperature stress should be superimposed on the floor design.
Keywords:connected structure; connection stiffness; connection form; seismic performance; temperature stress
