Structural Behavior of a Skew Two Span Reinforced Concrete Box Girder Bridge Model. Volume III - Response During Ultimate Loading to Failure

摘要

This is the third of a four volume sequence on the structural behavior of a skew two span four cell box girder bridge model as follows: Volume I - Design, Construction, Instrumentation and Loading; Volume II - Reduction, Analysis and Interpretation of Results; Volume III - Response during Ultimate Loading to Failure and Volume IV - Detailed Tables of Experimental and Analytical Results. In the present volume, the structural behavior of the skew box girder bridge model during ultimate loading to failure is described and interpreted. Analyses of the flexural collapse mechanism and shear capacity are presented and compared with experimental results. A comparison of the behavior of the skew bridge during ultimate loading with earlier tested straight and curved models is made. The possible design implications of the ultimate load behavior and the effects of skewness on the response are discussed.
