Analysis and Design of a Concrete Filled Steel Tubular Beam Footbridge with Corrugated Steel Web

摘要

The analysis and design of a concrete filled steel tubular beam footbridge with corrugated steel webs are presented in this paper. The decreased dead weight of corrugated steel web results in a lower construction cost of the bridge. The bridge crosses an existing roadway, whose traffic should not interrupt during the construction of the footbridge. The considerations of the design is introduced. By analyzing the bridge using MIDAS program, the strength, stiffness and dynamic behavior can meet the requirements of the codes.
