...Johan O. Jonsson In bridge dynamics the current practice is time domain analyses; consequently, there are specific requirements on load model formulation as well as computational intensity. This paper explores a spectral approach to evaluate bridge deck acceleration using an envelope spectrum...

... the laydown yard footprint that would be needed for construction. In addition, this structure type helped meet the 6 month roadway traffic closure window, because it allowed for an accelerated bridge construction (ABC) technique of floating the arch spans into place. This also helped meet the limited river...
