Seismic Performance of Composite Inverted Pendulum Light Railway Station

摘要

Elevated light railway stations are being widely used in big cities because of its advantages in utilization of urban space and structural integrity. Among these stations, an inverted pendulum structural form, characterized with long cantilevers and single columns, is most preferred as it can spare more space for the city. However, limitations on these structures in high-intensity earthquake regions have been highlighted due to their inferiority in lateral and vertical resistance. Consequently, a composite form of this inverted pendulum elevated structures is proposed in this study, seismic performance of this composite station is investigated using self-developed finite element software, it is proved to be robust enough in high-intensity earthquake regions. Finally, design suggestions are given for this composite inverted pendulum elevated structure.
