The interfacial bond parameters are quantified and modeled in this work through experimental analytical studies. A database comprising 628 shear tests of externally-bonded fiber reinforced polymer (FRP) joints is built for model development. newly derived closed-form solution used identification by matching the with test results. Factors that affect identified configurations models determined reasoning. Coefficients subsequently regression analyses. It found FRP-to-concrete width factor,...
Most existing models for evaluating the strength of fiber-reinforced polymer (FRP)-confined concrete columns are based in an early work. In this paper, a new model on Hoek-Brown failure criterion is proposed. The FRP-confined circular and square reviewed, evaluated, compared with proposed model. An updated database that includes large number test data then used to evaluate models. Comparisons between results demonstrate accuracy Apart from improved accuracy, also has unified form both...
Despite extensive investigations of bond stress versus slip modeling for RC structures, most existing stress–slip models are incomplete, discontinuous, and insufficiently accurate. These problems can cause nonconvergence other difficulties in computational simulations concrete structures that use bond-slip models. Through systematical analyses an database behavior data regressions, this work develops a unified model overcomes these is suitable numerical simulations. The given by single...
When the corner radius ratio ρ is defined as 2r∕b (corner divided by half breadth of column), circular and sharp cornered square columns are just two special cases when ρ=1 0, respectively. It quite logical that a confined concrete strength model for with should degenerate into However, this not case in any existing models, except early one Mirmiran et al. 1998. Extensive experimental testing on fiber-reinforced polymer (FRP)-confined have continuous variation from 0 to 1 has been undertaken...
A new and general stress-strain model for concrete confined by steel or fiber reinforced polymer (FRP) is developed in this work. One additional variable one constant are added to the well-known Popovics control type shape of curve. The proposed has simple, continuous, explicit expression can exhibit either hardening softening types responses. This provides a unified platform modeling different materials, such as FRP, help overcome inconsistency complexity. parameters determined analytical...
The adhesive attachment of fiber-reinforced polymers (FRP) laminate to the external face reinforced concrete structures is currently one most popular and effective methods for retrofitting strengthening structures. With this method, additional strength attached reinforcement transmitted into members through adhesion. However, relatively weak interface fundamentally limits efficacy method. Much effort has been made in research community improve bond develop models, but a satisfactory solution...
