Specific to blast loading, bond shear tests between carbon fiber reinforced polymer (CFRP) strips and concrete have not yet been reported in literature, the best knowledge of authors. Given high potential strengthening with CFRP increase resistance, it is necessary better understand dynamic interaction under impulse. This article presents a new experimental setup developed order study driven co...

Shear failure of B-C joints is recognized as the primary cause collapse various moment-resisting frame buildings during recent earthquakes. When joint subjected to huge forces severe ground shaking and its behaviour has a very much influencing on structure, sometimes it may Leeds entire structure. To study energy dissipation with different types combinations FRP sheets used retrofit BC in this ...

concrete shear walls are the most prevalent structural systems resisting lateral loads due to earthquakes in high-rise buildings. very large in-plane stiffness of shear walls provides an excellent drift control in the structure. however, structural damages and early code shortcomings threaten the efficiency of existing structural walls against earthquake. recently, fiber reinforced polymer (frp...

This paper presents the finite element modelling of shear-critical reinforced concrete beams strengthened with U-wrapped CFRP fabrics using ATENA. Fracture-plastic constitutive models, implemented in context smeared crack and crush-band approach, were employed to represent nonlinear behaviours concrete. U-wraps modelled as rein­forcement bonded surface an interface element, considering appropri...

Abstract Bangladesh is connected through bridges and many of them are experiencing damages due to the aging concrete, weathering effect, or excessive loading. Repair retrofitting those becoming inevitable make operational. In this study, a concrete bridge have been investigated non‐destructive tests numerical methods. A repair strategy for damaged girders has developed using epoxy injection, sh...

This paper presents a study of the shear capacity reinforced concrete (RC) beams strengthened in with externally bonded (EB) fiber polymer (FRP) composites, based on performance existing published tests. The main objective this is to create comprehensive overview different strengthening configurations and failure modes observed experimental In addition, influence following parameters efficiency...
