This paper presents a finite element (FE) analysis for predicting the flexural behavior of reinforced concrete (RC) beams strengthened with Fe-based shape memory alloy (Fe-SMA) strips using near surface mounted (NSM) method. Experimental results reported in literature were used to verify proposed FE model. analyses conducted OpenSees, general-purpose structural program. The RC beam specimens mo...

The main aim of the study was to perform selection procedure in order find optimal predictors for shear strength fibre reinforced polymers (FRP) used as internal reinforcement concrete (RC) beams. performed by adaptive neuro fuzzy inference system (ANFIS) and all available parameters are included. ANFIS model could be simplification analysis FRP-RC MATLAB software application prediction results...

Considering the influence of visible load-induced transverse cracks on chloride ion diffusion in cracked concrete in-service reinforced (RC) elements under marine environment, a typical volume with one crack was taken to establish governing equation. Assuming widths at outer lateral and bottom surfaces were equal, model predict equivalent coefficient put forward consider average width, spacing ...

a reinforced concrete member in which the total span or shear span is especially small in relation to its depth is called a deep beam. in this study, a new approach based on the adaptive neural fuzzy inference system (anfis) is used to predict the shear strength of reinforced concrete (rc) deep beams. a constitutive relationship was obtained correlating the ultimate load with seven mechanical a...

CFRP is an alternative technique for cracking control of high-chloride reinforced concrete (RC) beams. This research, therefore, investigates the strength performance and failure mode behaviour RC beams incorporated with sea sand bonded externally carbon fibre polymer (CFRP) plate. Sea used as a 100% replacement fine aggregate. Three batches were carried out in this including beam (no neither C...

Abstract To investigate the effect of nano carbon-fiber-reinforced polymer (nano CFRP) on retrofitting reinforced concrete (RC) structures, this article presented progressive collapse performance two half-scale four-bay RC frames including one control specimen S1 and S2 with CFRP beam ends. The was discussed by comparing crack patterns, failure mode, load–displacement curves, horizontal displac...

This study looks to propose a hybrid soft computing approach that can be used accurately estimate the shear strength of reinforced concrete (RC) deep beams. Support vector regression (SVR) is integrated with three novel metaheuristic optimization algorithms: African Vultures algorithm (AVOA), particle swarm (PSO), and Harris Hawks (HHO). The proposed models, SVR-AVOA, -PSO, -HHO, are designed c...

We use high resolution IRAS and 20 cm radio continuum (RC) images of a sample of 22 spiral galaxies to study the correlation between the far infra-red (FIR) and RC emissions within the galactic disks. A combination of exponential and gaussian profiles rather than a single exponential profile is found to be a better representation of the observed intensity profiles in the two bands. The gaussian...

The aim of this research work is to investigate the efficiency newly developed Natural Fiber Rope Reinforced Polymer (NFRRP) composites enhance shear strength reinforced concrete (RC) beams. Two types NFRRP were made using low-cost hemp and cotton fiber ropes. effectiveness confinement in increasing shear, energy dissipation, deformation capacities beams was studied. effect these natural ropes ...
