The application of inorganic composites has proven to be an effective strengthening technique for shear-critical reinforced concrete (RC) beams. However, accurate prediction the shear capacity RC beams strengthened with been a challenging problem due its complex failure mechanism and interaction between internal external reinforcements. Besides, predictive capabilities existing models are not s...

The objective of this study is to compare conventional models used for estimating the load carrying capacity reinforced concrete (RC) members, i.e., Current Design Codes (CDCs), with method based on different assumptions, Compressive Force Path (CFP) and a non-conventional problem solver, an Artificial Neural Network (ANN). For purpose, four databases details critical parameters (i) RC beams in...

The primary focus of this study is to evaluate the nonlinear response reinforced concrete (RC) frames with two types brick infills viz., unreinforced masonry infill (URM) and semi-interlocked (SIM) together lintel beams, subjected seismic loads. quantified in terms reduction factor base shear. Infill walls are modeled using double strut cyclic element. Nonlinear static adaptive pushover analysi...

Old Reinforced Concrete (RC) buildings are facing different degrees of structural deterioration and require proper strengthening to enhance their performance as well extend life span. Fabric reinforced Alkali-Activated Slag (AAS) matrix is proposed strengthen RC beams in this study. Seven with without were prepared tested under four-point bending. Test results indicate that use AAS replacement ...

This paper deals with the effect of fiber aspect ratio of steel fibers on shear strength of steel fiber reinforced concrete deep beams loaded with shear span to depth ratio less than two using the artificial neural network technique. The network model predicts reasonably good results when compared with the equation proposed by previous researchers. The parametric study invol...

This paper presents the shear performance of reinforced concrete (RC) beams with Tsection. Different configurations of externally bonded carbon fiber reinforced polymer (CFRP) sheets were used to strengthen the specimens in shear. The experimental program consisted of six full-scale, simply supported beams. One beam was used as a bench mark and five beams were strengthened using different confi...

Reinforced concrete (RC) is the most applied material in modern construction. Research on strengthening RC members has also been widely carried out. Over time, elements might deteriorate due to several factors, such as load, creep, or any other environmental aspects, leading stiffness strength reduction. Following rapid development of studies RC, structure Polymer (FRP) case overcome deteriorat...

In this research, steel plate-fiber concrete composite jackets (SPFCJ) was used to strengthen the RC beams. The accuracy of analysis method evaluated by modeling beams fabricated in laboratory, and a good agreement observed. Variables finite element (FEM) include strength class main beam (15, 20, 25 MPa), length (1.4 2.8 m), type (RC jacket, SPFCJ, CFRP sheet), jacket thickness (40, 60 80 mm). ...

In this study, experiments were performed on carbon fiber reinforced polymer (CFRP) retrofitted postfire concrete (RC) beams, followed by theoretical analyzes. Experiments conducted eleven RC which exposed to different fire durations and with CFRP in flexure shear. The experimental results indicated that shifted the failure flexure-shear of beams. beams experienced progressive peeling-off failu...

This paper examines the effectiveness of pure torsional loads on hollow reinforced concrete high-strengthened beams. Engineers need to know how much twist a structural member generates when exposed design it properly. is done through an experimental investigation behavior (RC) beams using twelve rectangular with varying parameters, such as spacing stirrups, influence steel fiber fraction, and m...
