Highway bridges are frequently constructed as simple span structures with steel or concrete girders and a cast-in-place concrete deck, spanning from one pier to another. At each end of the simple span deck, a joint is provided for deck movement due to temperature, shrinkage, and creep. Bridge deck joints are expensive and pose many problems with regard to bridge maintenance. Elimination of deck...

Spacetime media offers new opportunities for wave manipulation. Here we study superluminal slabs, and show that the amplitudes of the reflected waves are controlled by the velocity of the medium. In addition, the backward wave continuously scans from the specular to the collinear angle. A diagrammatic method is provided for insight into the deflection angles. A fundamental symmetry between suba...

Concrete structures have been widely used for many years to resist impact loads. Steel–concrete composite may be considered efficient in the emerging modern construction field. Hence, main objective of this research was study behavior steel concrete slabs with different shear connectors and compare them conventional slabs. Seven specimens dimensions 500 × 50 mm were cast, which included plain c...
