Abstract It is well known that highway bridges are subjected to fatigue as they work under live loads with different frequencies and amplitude. The safety level for required by Brazilian codes still unknown, especially prestressed concrete girders. Also, current studies on reliability of only evaluate bending. This assesses the provided design standards a bridge, using weigh-in-motion (WIM) dat...

Title of Document: EFFECTS OF WINGWALL CONFIGURATIONS ON THE BEHAVIOR OF INTEGRAL ABUTMENT BRIDGES Andreas Paraschos, Doctor of Philosophy, 2016 Dissertation Directed By: Professor Amde M. Amde Department of Civil and Environmental Engineering This research includes parametric studies performed with the use of three-dimensional nonlinear finite element models in order to investigate the effects...

The wind flow around twin-box decks is particularly complex due to the very important role played by slot distance between girders and presence of downwind box that immersed in wake upwind box. Detailed experimental studies on three-dimensional features this deck typology are certainly challenging, CFD simulations have not tackled problem so far. goal 3D LES piece research shed some light decks...

Accepting the challenge of the future in the field of civil engineering smart structure applications, the province of Manitoba is undertaking the responsibility of constructing the first bridge in Canada totally prestressed and reinforced for shear by cru:bon fibre reinforced plastic (CFRP) reinforcement. Portion of the concrete deck slab is also reinforced exclusively by FRP reinforcements. Th...
