In this paper, the lap splice length and the long-term (fatigue) performance of lap-spliced carbon FRP laminates were investigated. Lap-spliced CFRP coupon specimens were fabricated with a splice length of 12.7, 25.4, 38.1, 50.8, 76.2, and 101.6 mm. To eliminate the bending on the lap splice joint, a symmetric specimen configuration was adopted. The width of the specimens was 38.1 mm. These spe...

Abstract Shape memory alloy (SMA) materials possess complete superelasticity or pseudoelasticity above the austenite finish temperature (Af) and many unique mechanical, thermal, thermal–mechanical and electrical properties compared with other conventional materials. Many studies have reported that the superelastic and hysteresis properties of SMA materials can absorb energies coming from extern...

The effect of changing operating temperature on the compressive response of IM7/PETI5 composite laminates is investigated within this paper. The three temperatures evaluated for this study were –129C, 21C, and 177C, a spectrum from cryogenic to an elevated operating temperature. Laminate compressive strength property testing was conducted using the Wyoming Combined Load Compression fixture to g...

This paper presents a study that forms part of an ongoing project on the seismic retrofit of reinforced concrete (RC) structures with fibre-reinforced polymer (FRP). In this study, a stress-strain model for FRP-confined concrete subjected to cyclic loading was implemented into OpenSees to support the performance-based design of FRP jackets for the seismic retrofit of RC columns/structures. Init...

We introduce a new reflection principle which we call “Fodor-type Reflection Principle” (FRP). This principle follows from but is strictly weaker than Fleissner’s Axiom R. For instance, FRP does not impose any restriction on the size of the continuum, while Axiom R implies that the continuum has size ≤ א2. We show that FRP implies that every locally separable countably tight topological space X...

Stackable gels comprised of layers of dissimilar polymers were synthesized by combining conventional free radical polymerization (FRP) and atom transfer radical polymerization (ATRP) using two approaches: (i) polymerization of a pre-gel solution containing a monomer and cross-linker introduced on top of a previously prepared gel, and (ii) simultaneous polymerization of two immiscible pre-gel so...

Extensive studies have been undertaken on the local buckling of FRP members. However, scope existing research largely remains limited to those with rectangular faces. As geometry member faces can affect capacity, thin-walled members possess higher loads for a given volume material when properly shaped. such, consideration non-rectangular is necessary, not only cater applications where profiles ...

Corrosion of steel reinforcement in an aggressive environment constitutes a serious problem for many reinforced concrete (RC) structures. Fiber-reinforced polymers (FRP) rebars represent a potential solution to this situation. Even if FRP reinforcement shows a good resistance to electro-chemical corrosion, long-term behavior must be investigated and proven. The mechanical properties of FRP rods...

Recent research has focused on rehabilhation and strengthening of steel structures and bridges using fiber reinforced polymer (FRP) materials. The bond behavior of FRP materials to steel structures is quite different from lhat of concrete structures. Preliminary test results showed the occurrence of very high bond stresses for most strengthening applications due to the amount of strengthening r...
