Seismic Performance and Shock Absorption Design of the High-Rise Corridor Structure of Yangcheng Lake Jin Jiang International Hotel

In the Suzhou Yangcheng Lake Scenic Area， a comprehensive hotel project featuring a conjoined tower structure was undertaken. To ensure the safety of the high-rise conjoined structure under seismic action and to reduce the interaction between the corridor structure and the main structure， a combined isolation system consisting of lead rubber bearings and viscous dampers was installed at the joints between the corridor structure and the main structure. Using the MIDAS/Gen software platform， a full model of the conjoined structure was established for response spectrum analysis and dynamic elastic-plastic time-history analysis. The dynamic responses of the main structure with and without the conjoined configuration were compared. The results showed that the bearing device provided effective damping and energy dissipation， effectively mitigating adverse interactions with the corridor structure. After the installation of the isolation system， all performance indexes of the conjoined structure meet the requirements of seismic design.
