A linear, elastic, finite element analysis of 288 bridges was done for both positive and negative moments. All these structures had a regular geometry, with a uniform concrete deck resting on five identical prismatic and equally spaced steel built-up plate girders. Spans ranged from 44 to 124 feet, girder spacing 6 to 10 feet, skew angle varied from 0 to 63 degree, and, thickness of slab was between 6 to 12 inch.

A computationally efficient mesh for the finite element model was finalized after conducting a detailed convergence study on different simply supported and continuous bridges.","abstract_html":"Influence of different variable on the structural performance of two lane, two span, continuous composite I-beam bridges were investigated.
