finite element based fatigue assessment of corrugated steel web beams in highway bridges
this paper presents a finite element analysis and its related experimental test of corrugated steel web beams subjected to fatigue loading. a particular focus in this study was set on the fatigue failure arising from the web-to-flange welded joint of the corrugated steel web beam. a detailed three-dimensional finite element model which explicitly includes the geometry of the web-to-flange welds...
متن کاملFatigue Load Model for Highway Bridges in Heavily Loaded Areas of China
Fatigue is one of the main factors that cause the collapse of steel bridges. Anti-fatigue design therefore draws close attention all over the world. The design must have a fatigue load model based upon native traffic load conditions. But the Chinese steel bridge design specification does not include any fatigue load model for anti-fatigue design. So it is imperative to develop the model. This p...
متن کاملLive 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...
متن کاملRecent Innovation for Concrete Highway Bridges
A new generation of concrete highway bridges has recently been built in Canada using new design concepts and advanced materials for reinforcing and prestressing concrete . This paper describes briefly the design and construction of three bridges. The first smart concrete highway bridge (Centre Street, Beddington Bridge, Calgary, Alberta) is prestressed by carbon fiber reinforced plastic (CFRP) ...
متن کاملRepair and Strengthening of Highway Bridges with FRP
Two different design problems are commonly encountered by highway bridge maintenance engineers: the upgrade of existing members to handle increased load demand, or the repair of bridge members which have experienced impact events due to overheight vehicles. This paper shows that through the use of carbon fiber reinforced (CFRP) materials highway bridge girders can be effectively strengthened or...
