| Abstract: | Four footbridges were constructed on the U-shaped structure of Qianhu Expressway in Nanchang.By comprehensively considering the surrounding constraints,the open steel truss beam footbridge is used.The Midas Civil 2015 finite element software is adopted to carry out the modeling calculation and analysis,and the amount of steel for the open steel truss beam bridge is compared and analyzed,which can be referred for the design of the similar urban open steel truss beam footbridges. |
