Abstract

Owing to the advantages of lightweight, high-efficiency pre-stress, crack-resisting, corrugated steel web trough girders (CSWTGs) gain wide applications in rail transit viaduct structures. Viewing the inevitable torque caused by vehicle sway, wind loads, and curved alignments, and the limited research related to the torsional performance of CSWTGs, finite element simulations were constructed and calculated to explore the impact of corrugated steel web thickness, boundary conditions, height-to-span ratio, and aspect ratios on the torsional performance of CSWTGs. Results indicate ultimate torsional capacity of CSWTGs increase with the enhancement of corrugated steel web thickness for typical flexural failure happened when the web thickness higher than 4mm. However, a premature buckling failure happened on the CSWTGs with web thickness of corrugated steel lower than 2mm leading to a huge decline of torsional capacity. Additionally, fixed boundary conditions, higher height-to-span ratio and lower aspect ratios can significantly enhance both the ultimate torsional capacity and torsional stiffness of CSWTGs.
