“…It was concluded that the strength models [2,[36][37][38] based on steel confinement give rise to higher estimation than experimental ones in each relevant strength range known in the current literature [1,5,33,73]. While the prediction performance of some models are restricted concerning range [22], some of those models are also capable of reasonably predicting wider data ranges [5,33,41].…”

This study addresses a design oriented combined model to predict the ultimate strengths and ultimate strains in an extensive range of unconfined strength (7 to 190 MPa) for the axially loaded fiber-reinforced polymer (FRP)-wrapped circular short columns. Modified Hoek-Brown strength criterion, which was previously extended to FRP-confined concrete from 7 to 108 MPa, is revisited and verified. An empirical strength model beyond 108 MPa encompassing ultra-high strength concrete (UHSC) and ultra-high performance concrete (UHPC) data, as well as empirical strain models, are defined to accomplish the design oriented combined model. This article especially focuses on the verification of the proposed strain models. The assessment performances of those models for carbon FRP (CFRP) and glass FRP (GFRP) confinement are compared with specific models in the current literature. Strength and strain predictions for UHSC and UHPC are integrated into the design oriented combined model as well. The assessments on this model agree with the experimental results in high accuracy.

Fiber-reinforced polymer (FRP) materials have been emerged as very effective and reliable materials for the repair, strengthening, and retrofitting of existing reinforced concrete (RC) structures. After a brief introduction on the variety of FRP materials and strengthening techniques for applications on civil structures, the basic principles for designing different strengthening configurations with these materials are herein presented and discussed. First, the bond mechanism, at the base of the structural performance of each type of external strengthening with FRP materials, is discussed both for externally bonded reinforcements (EBR) usually applied in the shape of sheets and plates and for near surface-mounted (NSM) reinforcements usually applied in the shape of bars or strips. Then, flexural, shear, and confinement applications are examined in detail and the basic mechanical principles of performing safety verifications are illustrated with reference to both provisions from current international design guidelines and innovative theories from up to date scientific literature. Finally, an overview on the potentialities of FRP materials for seismic strengthening is presented
