Flexural performance of recycled concrete beam reinforced with modified basalt fiber and nano-silica
To increase the surface roughness of basalt fiber (BF) and enhance the bonding properties with the concrete matrix, three modified solutions were prepared to treat the BF surface.

OPTIMIZATION OF SINGLY REINFORCED RC BEAMS
The main objective of this paper is to achieve an optimal design for the reinforced concrete beams. Optimization of beams results in saving in cost. The objective function is to minimize the total cost of the beam. The cost of each beam includes the cost of concrete, reinforcement and formwork.

Analysis of FRP shear strengthening solutions for reinforced concrete beams considering debonding failure [PDF]
In this paper, a fiber beam model previously developed by the authors for the nonlinear analysis of strengthened elements, including the effects of shear, is used to predict the response of reinforced concrete (RC) beams strengthened in shear with fiber ...

Deformation limit states for corroded reinforced concrete beams and columns [PDF]
Since deformation quantities have become principal design consideration in performance-based seismic design (PBSD), it is necessary to evaluate the deformation behavior of corroded RC structures for life-cycle oriented PBSD philosophy.

Retrofitting of RC Element Beam
Structures with the passing of time they lose their strength because of many reasons like seismic activity, soil failure due to ground motion, arises problem like damaging of roof, foundation, walls, pillars, column and beams for these structures becomes statically unsafe and solution to these problem is Retrofitting.

Twelve prototype rectangular RC beams (120 x 150 x 1000 mm) were constructed and evaluated using flexural test to investigate the employment of advanced composites in repairing corroded reinforced concrete (RC) beams. Three concrete mixtures with effective w/c ratio of 0.4 and cement content of 370 kg/m3 were utilized in the study: control ordinary ...
