Abstract: Due to the orthogonal elastic properties and significant two-way bending action, orthotropic plate theory may best be used to describe the behavior of concrete filled grid bridge decks. The current AASHTO LRFD specification ...

Abstract: Concrete filled grid bridge decks exhibit orthogonal elastic properties and significant two-way bending action enabling orthotropic plate theory to determine structural response for these elements. Current American Association ...

Abstract: Tests were performed on full-size prefabricated steel stair assemblies to assess seismic interstory drift response combined with factored gravity loads. The stair assemblies were production-run units of a standard system ...

Abstract: A nonlinear method of finding two-dimensional supercavitating sections in a cascade is developed. The load distribution is taken from linear theory for low drag super-cavitating foils in a ...

Abstract: A locally steep surface gradient or ?jump? may be expected on any steady surface current whose strength U decreases horizontally from supercritical (U > cmin) to subcritical (U < cmin), where cmin is the minimum phase ...

Abstract: Reducing greenhouse gas emissions almost certainly requires adding a price to those activities that cause emissions. Policy makers have largely overlooked the most direct option, which is to set a price on emissions (an ...

Abstract: An inviscid mechanism is proposed for the breakup of the jet in a plunging surface wave. Streamwise perturbations of the original surface are shown to grow rapidly owing to stretching of the thin jet and to drastic reduction ...
