Seismic Performance Analysis of Cylindrical Shell Structure of Railway Station
With the rapid development of high-speed railway,the number of small and medium passenger station buildings is increasing gradually.Cylindrical shell structures are widely used in station buildings due to their functional service capabilities and architectural aesthetics.However,the seismic performance and mechanical properties of cylindrical shell structures used in western regions with high seismic intensity need further investigation.A three-dimensional mechanical model of the cylindrical shell structure is established using finite element software,and the dynamic response calculation of the cylindrical shell under rare earthquake excitation is completed,and the displacement,acceleration,stress response and structural damage of key parts of the structure are studied.The results show that the middle part of the structure has a great influence on the overall seismic effect,and the weak link of seismic resistance is located at the column base and beam-column joint of the middle shell.Under rare earthquakes,the maximum elastic inter-story drift ratio of the shell structure reached 1/88,which meets the specification requirements.The designed structure can achieve the expected seismic precaution objectives.
