WebWhen only the deck slab is to be continuous over two or more spans, the closure diaphragm may be designed and detailed in accordance with the recommendations of … Webthe intermediate diaphragm effect may increase or decrease the rating factor. This may make a difference when a bridge load rating is near 1.0, namely, the pass or fail line. 3-D FEM A simplified, 3-D, elastic FEM with GT STRUDL was used to analyze all the bridges in the parametric study.
