Experimental and Theoretical Investigation of Horizontally Curved Girder Highway Bridges.

摘要

An investigation was made to determine the structural behavior of horizontally curved girder highway bridges under either dead or live loads. Experimental data were collected from three such bridges located in Birmingham,Alabama,and correlated with results obtained from theoretical analyses. Presented in this report are:Stresses,deflections,and rotations calculated by each of the two theoretical analyses used in this investigation;Procedures for field testing the three bridges to obtain experimental values for stresses,deflections,and rotations;Comparison of theoretical and experimental values for stresses,deflections,and rotations;and Detailed comparisons of theoretical results obtained by the two theoretical methods of analysis.
