Abstract Steel plate girders with I‐section are frequently used in industrial buildings and bridge design as prismatic members that means parallel flanges rectangular webs. The structural efficiency can significantly be achieved if such designed tapered webs non‐rectangular Depending on the flange inclination moment diagram, stress of is affected also known Résal effect. Furthermore, improved f...

A new analytical method to predict the torsional capacity and behavior of R.C multi-cell box girders strengthened with carbon fiber reinforced polymer (CFRP) sheets is presented. Modification was done on the Softened Truss Model (STM) in the proposed method; the concrete torsional problem is solved by combining the equilibrium conditions, compatibility conditions and constitutive laws of materi...

Two different design problems are commonly encountered by highway bridge maintenance engineers: the upgrade of existing members to handle increased load demand, or the repair of bridge members which have experienced impact events due to overheight vehicles. This paper shows that through the use of carbon fiber reinforced (CFRP) materials highway bridge girders can be effectively strengthened or...
