“…[1][2][3][4] The suspension of many racing cars used in Formula SAE consists of a carbon fiber and aluminum alloy bonding structure [5][6][7] as shown in Figure 1. Compared with the traditional repair method for the metal and concrete, such as welding, bolting, and attaching steel plates, the CFRP composite provides higher strength with less weight and higher resistance against the effects of high temperatures and humid environments.…”

According to previous studies, the bond strength between the carbon fiber-reinforced plastics and metals mainly depends on the bond layer between the carbon fiber-reinforced plastic composites and the metal. This article presents the results of the experiments conducted on the tensile bond strength between the carbon fiber-reinforced plastic tubes and aluminum joints. The parameters examined in these experiments include adhesive type, surface roughness of the bonded area, and thickness and length of the bond layer. The results show that the 3M DP-460NS Off-White adhesive was suitable for our experiment. The bonded surfaces of the specimens were smoothened with a P600 sandpaper to achieve higher bond strengths with the adhesive. For the six bond thicknesses tested, a thickness of 0.2 mm was optimal for the tensile experiments. The ultimate tensile force was approximately directly proportional to the bond length.

“…The retrofit of seismically deficient structures before earthquakes provides a feasible and cost-effective approach to improving their load carrying capacity and reducing their vulnerability. Over the last decade, the use of externally bonded fibre composite materials (FRPs) has offered engineers a new solution for strengthening seismically deficient buildings [1]. Comparatively to other traditional strengthening techniques, FRP materials possess advantages such as high strength to weight ratio, high resistance to corrosion, excellent durability, ease and speed of in-situ application and flexibility to strengthen selectively only those members that are seismically deficient [2].…”

A full-scale two-storey RC building with poor detailing in the beam-column joints was tested on a shake table as part of the European research project ECOLEADER. After the initial tests which damaged the structure, the frame was strengthened using carbon fibre reinforced materials (CFRPs) and re-tested. This paper investigates analytically the efficiency of the strengthening technique at improving the seismic behaviour of this frame structure. The experimental data from the initial shake table tests are used to calibrate analytical models. To simulate deficient beam-column joints, models of steel-concrete bond-slip and bond-strength degradation under cyclic loading are considered. The analytical models are used to assess the efficiency of the CFRP rehabilitation using a set of medium to strong seismic records. The CFRP strengthening intervention enhanced the behaviour of the substandard beam-column joints, and resulted in substantial improvement of the seismic performance of the damaged RC frame. It is shown that, after the CFRP intervention, the damaged building would experience on average 65% less global damage compared to the original structure if it was subjected to real earthquake excitations.2

“…Asimismo, el refuerzo como técnica de rehabilitación es eficiente, en las estructuras que no cumplen con los requisitos necesarios para garantizar un buen comportamiento durante eventos extremos, bien sea por inadecuados diseños o por baja calidad en la construcción, por cambio de las condiciones de uso o por la necesidad de adaptar la estructura a los requisitos de diseño actuales (Pendhari, 2007).…”

RESUMENEste artículo estudia las variaciones en el comportamiento estructural que implica el reforzamiento con polímeros reforzados con fibras o FRP por sus siglas en inglés (Fiber Reinforced Polymers). Para ello se elaboraron 50 modelos computacionales, que se analizaron con diversas características geométricas tales como: irregularidad en planta, irregularidad en elevación, vigas banda, vigas descolgadas, diferente número de pisos, entre otras, los cuales fueron predimensionados con el Código Ecuatoriana de la Construcción 2002 y analizadas con las Normas Ecuatorianas de la Construcción 2011. Una vez identificadas los elementos de menor capacidad, se refuerzan con FRP de acuerdo al ACI 440, para ser analizadas nuevamente y establecer las comparaciones pertinentes entre los análisis eigenvalores, modal espectral y Pushover estático, de los cuales se observa que el FRP, disminuye los periodos de vibración, aumenta la frecuencia, disminuyen los factores de participación modal y reduce las derivas en un escaso porcentaje, pero aumenta considerablemente la capacidad de la estructura permitiendo soportar mayores solicitaciones con un menor desplazamiento en la azotea. ABSTRACTThis article studies the variations in the structural behavior that imply the reinforcement with fibers reinforced polymers or FRP, by its acronym in English (Fiber Reinforced Polymers). For this purpose, 50 computational models were elaborated, which were analyzed with different geometric characteristics such as: irregularity in the floor, unevenness in elevation, band beams, raised beams, different number of floors, among others, which were predimensioned with the Ecuadorian Code of Construction 2002 and analyzed with the Ecuadorian Construction Standards 2011. Once the elements of lower capacity are identified, they are reinforced with FRP according to ACI 440, to be analyzed again and to establish the relevant comparisons between the eigenvalues, modal spectral and static Pushover analyzes, of which it is observed that the FRP decreases the periods of vibration and increase the frequency, decrease the modal participation factors and reduce drifts in a small percentage, but considerably increases the capacity of the structure allowing it to withstand greater stresses with less displacement on the roof.
