Strengthening of steel-reinforced concrete structural elements by externally bonded FRP sheets and evaluation of their load carrying capacity

2014

Abstract The paper proposes a preliminary design tool for reinforced concrete (RC) elements strengthened by fiber-reinforced-polymer (FRP) sheets to be used in civil engineering applications and in particular in medical buildings. The design strategy is based on limit analysis theory and utilizes a numerical procedure which provides a direct method to determine peak load, failure mode and critical zones of the structural elements of interest.

2014

The paper has proposed a limit analysis procedure for a preliminary design of RC elements strengthened by externally bonded FRP sheets. The procedure, based on a multi-yield-criteria limit analysis approach, has led to a reliable prediction of peak loads and failure modes of the analyzed elements (slabs) by simultaneously considering the limit state of the constituent materials, so resulting very useful in many applications of engineering interest. The attention has been focused on hospital applications in which increment of service loads or realization of openings can weaken some structural elements that have been strengthened by FRP sheets.

Symmetric Galerkin Boundary Element Metod for 3D analysis

1999

The mixed boundary value problem is dealt with by Galerkin approach in 3D linear elasticity via a system of boundary integral equations. This paper presents a method for computing a solving system coefficient made up of double surface integrals with hypersingular kernel. This method employs the Schwartz distribution theory in order to obtain the closed form of the first surface integration which represents the traction. The successive surface integration of the weighed traction having a kernel with logarithmic singularity uses known numerical techniques. This formulation requires C° continuity of shape functions modelling the source represented by the displacement discontinuity.
