Wind Load Analysis of Railway Passenger Station Building and Canopy
摘要
Abstract
With the development of railway engineering,there have been more and more large-span railway passenger stations and canopies.Due to the complexity,uniqueness and large span of the station and the canopy structure,the wind load value can not be obtained from the existing national standard Structural Load Specification,and the accurate and reasonable wind load value is very important for structural safety and control of project cost,which has made it necessary to carry out wind tunnel test.Taking a railway passenger station and its canopy as the engineering background,the rigidity model is selected as the research object to measure the surface wind pressure coefficient,and finite element software is used to analyze wind-induced dynamic response and calculate the node displacement and the wind pressure coefficient.Finally the equivalent wind load values of the station and the canopy structure are obtained.The results show that the equivalent wind load values are decreasing in the wind direction and the value is very large at the roof edge of the windward side.关键词
