in reinforced concrete design, there are situations where transfer of shear across a specific plane needs to be considered. examples of such situation include corbels, bearing shoes, ledger beam bearing, and a host of connection between precast concrete elements. in this study, the shear transfer behavior of reinforced concrete is investigated experimentally by conducting test on 6 precracked p...

In this study, the complex behavior of steel encased reinforced concrete (SRC) composite beam–columns in biaxial bending is predicted by multilayer perceptron neural network. For this purpose, the previously proposed nonlinear analysis model, mixed beam-column formulation, is verified with biaxial bending test results. Then a large set of benchmark frames is provided and P-Mx-My triaxial ...

Based on the experimental study for seismic performance of FRP reinforced concrete beam-column joints, two-storey two-span plane frames were taken for examples, in which the static elastoplastic analysis (the pushover method) was carried on the joints of the FRP strengthened concrete frames, and then the comparative analysis was made on seismic performance of RFP strengthened frame structure th...

introduction: globally, the need for radiotherapy as a part of cancer management increases every year. thus, the shielding for megavoltage radiotherapy rooms is of great importance. materials and methods: in the present study, 14 types of developed high-density concrete with densities ranging from 2.45 to 5.11 were simulated by using monte carlo method. the linear attenuation coefficient and th...

The prestressing force is transferred to the concrete during the slack period of precast concrete structures fabrication. To contribute to a better understanding of the armor compliant behaviors during the mentioned process, a custom quasidistributed Bragg Grating optical fiber sensor system is designed, fabricated and embedded into a prestressed concrete prismatic beam. The experimental works,...

Abstract: This research examines the performance of strengthened non-uniformly corroded reinforced self-consolidating concrete (SCC) members. This paper focuses on three aspects of concrete including corrosion, concrete cover loss, and repair technique. Up to a 50% corrosion level is considered in this study. Corrosion was experimentally induced and was simulated in other cases. Twenty-six rein...

The interface between concrete and steel in reinforced concrete governs the interaction between the two types of materials under loading. When the interface is seriously damaged, such that a macro-crack is formed, de-bonding takes place or large slip occurs, and the load-transferring capacity of the interface will drop dramatically. In this study, a vibration-based method is presented to detect...

This paper investigated the effects of seawater curing of concrete made by Micro-Nano Air Bubbles (MNAB) on compressive, flexural and tensile strengths of the concrete. This product will be applicable for rehabilitation or repair of coastal RC structures. In this research, the effect of different combinations of concrete ingredients including 0-100, 25-75, 50-50, 75-25, and 100-0 percent ...
