| Abstract: | The arched beam string structure is adopted in the design of steel structure platform canopy without pillar of Yan'an Railway Station.Quality and safety insurance methods are used in factory's sectional making,inhaul cable laying,tension,internal force and deformation test,hoisting,positioning,and grouting in the top chord pipe.The beam string deformation and internal force control are within an acceptable range,which can shorten the construction period and achieve good economic benefits. |
