In this paper, a sensitivity analysis of artificial neural networks (NNs) is presented and employed for estimating the patch load resistance of plate girders subjected to patch loading. To evaluate the accuracy of the proposed NN model, the results are compared with the previously proposed empirical models, so that we can estimate the resistance of plate girders subjected to patch loading. The ...

As a service to the bridge design profession, Bethlehem Steel has conducted hundreds of studies of steel plate girder bridges using its Preliminary Bridge Girder Optimization Program. The program is unique because it optimizes plate girder designs on the basis of least cost, not least weight. An evaluation of many study results leads to a number of guidelines which are offered in this paper. Wh...

Several theories are available in the literature to predict ultimate shear resistance of plate girders, generally known as tension field theories. It is already found out, by many researchers, that prediction majority models mostly over-conservative for non-rigid end post steel girders. So, there a need development accurate finite element models, which could strength better than theoretical mod...
