Analysis on the Truss Structure Design of a Temporary Construction Project
Currently,the continuous development of na-tional construction puts forward more standardized re-quirements for the temporary buildings in the early stage of the construction project.Based on the temporary mixing station's bunker of a railroad project,this paper analyzes the selection of cross-section of space truss structure and the design of steel joist in the temporary construction engi-neering through model comparison calculation,and studies the reliability of the column extraction treatment for large-span space truss structure.Finally,the design parameters of temporary truss building that meet the requirements of national codes are demonstrated,and the standardized and optimized design scheme of the temporary truss is pro-posed.It has certain reference value for reducing the pro-ject preliminary investment and shortening the construc-tion period of the main engineering.
