MODEL STUDY OF HORIZONTALLY CURVED BOX GIRDER

This paper describes an experimental study of a single span horizontally curved plexiglass box-girder beam with diaphragms and flange overhangs. Static loads were applied at midspan to cause a complex pattern of membrane and bending stresses with the effects of diaphragms clearly evident. Experimental results in typical cases are shown graphically and compared to the results of a special purpose finite element program developed especially for curved box analysis. Good agreement between experimental and analytical results were obtained.
