Development and implementation of CFRP post-tensioning system for bridge strengthening

development and implementation of an optimized control strategy for induction machine in an electric vehicle

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...

Bond Behavior of a CFRP Strengthening System for Steel Structures

This paper summarizes an experimental program supported by an analytical modeling study undertaken to investigate the bond behavior of carbon fiber reinforced polymer (CFRP) materials used for strengthening steel structures. The experimental program consisted of three double-lap shear coupon tests and five large-scale beam tests. Different methods to reduce the bond stress concentrations near t...

Shear Strengthening Using Cfrp Sheets for Prestressed Concrete Bridge Girders in Manitoba, Canada

What Is Post-tensioning?

December 2000 OVERVIEW Post-tensioning is a method of reinforcing (strengthening) concrete or other materials with high-strength steel strands or bars, typically referred to as tendons. Post-tensioning applications include office and apartment buildings, parking structures, slabs-on-ground, bridges, sports stadiums, rock and soil anchors, and water-tanks. In many cases, posttensioning allows co...

Shear Strengthening Using Cfrp Sheets for a Prestressed Concrete Highway Bridge in Manitoba, Canada

The use of heavier trucks demanded upgrading of a twenty-seven year old bridge in Winnipeg, Manitoba, Canada. Analysis of the precast prestressed concrete girders using the current AASHTO Code indicates a deficiency in the shear capacity. Shear strengthening using Carbon Fibre Reinforced Polymer (CFRP) sheets provides a low-cost solution by increasing the speed of construction and reducing traf...
