چکیده
The numerical modeling of structures is a widely preferable approach to investigate the structural behavior RC beams since it delivers inexpensive predictions for confirming required goals concurrently with reducing casting, testing time, and effort. Shear-strengthening reinforced concrete (RC) using externally bonded (EB) fiber-reinforced polymers (FRPs) has attracted much attention due fact that FRP strengthening technique ability alter distribution stresses between elements increase load-carrying capacity. A significant number experimental studies have been carried out test monotonic shear-strengthened beams. Conversely, limited research performed such performance. VecTor2 software developed based on modified compression field theory (MCFT) directed examine retrofitted specimens polymer (FRP) composites. To authors’ knowledge, not explored in literature MCFT approach. main objective this study detect software’s capability predicting outcomes This two stages. Initially, involves development an accurate finite element model simulate control specimens. quality assessed by comparing results outcomes. In second phase study, beam accommodate presence external accuracy again measured its measurements. goal these phases ensure captures actual tested Additionally, distinctive approaches are investigated represent models verified through comparisons terms ultimate loading capacity, load–deflection relationships, failure modes. It can be stated validated provides alternate means evaluating both strengthened non-strengthened predicted compare very well when discrete truss employed Furthermore, useful information crack patterns

Behavior of Coupling Beams Strengthened with Carbon Fiber Reinforced Polymer Sheets
In this research, using the results of 6 tests, the effect of Carbon Fiber Reinforced Polymer (CFRP) sheets on the behavior of reinforced concrete coupling beams of shear walls is studied. First, in the experimental part of the study, four coupling beams with different reinforcements were manufactured and tested. Then, after the failure of the specimens, two of them were rehabilitated and stren...

متن کاملHysteretic Behavior of Conventionally Reinforced Concrete Coupling Beams in Reinforced Concrete Coupled Shear Wall
This paper presents the experimental results of four full-scale coupling beams in which only horizontal reinforcements are placed, without diagonal reinforcements, with the aim to develop reinforcement details for coupling beams used in connecting side walls in a wall-slab structural system. Each coupling beam specimen was designed according to the deep-beam design procedure that does not use d...
متن کاملBehaviour of Reinforced Fibrous Concrete Beams under Reversed Cyclic Loading
When earthquakes occur, energy released by the earthquake gets induced into the structure as ground motion and this energy has to be dissipated for safety reasons. To release seismic energy, the structure should damage in such a way that on one hand, collapse of structure should not occur and on the other hand, after the earthquake, damage should be economically feasible to repair. To avoid the...
