Long-Term Monitoring of Temperature Effect on Horizontal Rotation Angle at Beam Ends of a Railway Steel Truss Bridge
Publication: Journal of Bridge Engineering
Volume 24, Issue 10
Abstract
In steel truss bridges, some truss members are exposed to solar radiation, while others are shaded by steel decks, which may result in large temperature gradients between truss members and further induce significant horizontal rotation angles (HRAs) at beam ends of steel truss bridges. Therefore, using the long-term monitoring data from a railway steel truss bridge with a 2-layer deck, the effect of temperature gradients on HRA was studied. Several analytic methods related to this topic are proposed, including a method for identifying large temperature gradients in steel truss bridges, a method for identifying whether the thermal load is the dominant load affecting HRA, and a method for identifying what kinds of temperature gradients have significant impacts on HRA. The results show that there are significant vertical temperature gradients between the top and bottom truss members in the side trusses and significant transverse temperature gradients between the bottom truss members, the thermal load is the dominant load affecting HRA compared with the other dynamic loads, and the temperature gradient between the bottom truss members in the side trusses has the greatest effect on HRA.
