"桥建合一"型高架车站抗震韧性评估
Seismic Resilience Assessment of"Bridge and Construction Integration"Type Elevated Station
摘要
Abstract
"Bridge and construction integration"type elevated station is an important hub in a large transportation network,and its seismic resilience is crucial for the post-earthquake recovery of urban functions.This paper summarizes the performance level classification indicators and resilience evalua-tion coefficients for the main components of"bridge and construction integration"type elevated station based on GB/T 38591-2020 Building Seismic Resilience Evaluation Standard.A typical"bridge and construction integration"type elevated station is selected as the research object for seismic resilience assessment.Firstly,a set of seismic resilience assessment procedures for elevated station is proposed.Then,the OpenSees software is used to conduct nonlinear dynamic time-history analysis on the elevat-ed station to obtain engineering demand parameters under different earthquake intensities.Finally,the seismic resilience assessment is carried out focusing on component damage,repair costs,repair time,and casualties.The research results show that under different earthquake intensities,component dam-age of"bridge and construction integration"type elevated stations is mainly concentrated on frame beams and infill walls.The repair cost of the elevated station is determined by the repair cost of struc-tural components,with the repair cost of frame beams accounting for over 80％of the total cost.The post-earthquake repair time and casualty rate of"bridge and construction integration"type elevated station are both at low levels.This paper can provide a theoretical reference for the seismic resilience assessment of"bridge and construction integration"type elevated stations.关键词
