An Investigation on the Parameters Influencing the Pounding in Highway Bridges
The present aim of this study is to investigate the effect of different parameters influencing pounding in highway bridges. Pounding is the result of a collision between two parts of the deck and/or the deck and abutments at the separation distance during the earthquake. In the present study, the period ratio of the adjacent frames, ground motion spatial variation, and soil-structure interacti...
متن کاملfinite 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...
