Live load model for highway bridges *

Load models are developed for highway bridges. The models are based on the available statistical data on dead load, truck loads and dynamic loads. The paper deals mostly with the static live load. The model is derived from truck surveys, weigh-in-motion measurements and other observations. Simple span moments, shears and negative moments are calculated for various spans. Extreme 75 year loads a...

The Effect of Diaphragms in Prestressed Concrete

16. Abstract Four scale microconcrete model bridges were tested. Experimental variables included span, skew angle, stiffness, location and number of diaphragms. Service load level behavior was studied under static, cyclic and impact loads with successive removal of diaphragms. Behavior at overload and ultimate load conditions was documented from ultimate static and impact load tests. Characteri...

Design aspects of steel I-girders with corrugated steel webs

Corrugated web girders represent a new structural system emerged in the past two decades. The girder’s flanges provide the flexural strength of the girder with no contribution from the corrugated web which provides the girder’s shear capacity. Failure of the web occurs by steel yielding, web buckling or interactively between them. Lateral torsion and local flange buckling of corrugated web gird...
