Reinforced Concrete Structures, traditionally using steel rebars, are vulnerable to corrosion under severe exposure conditions. This can result in several drawbacks such as concrete deterioration, reduced serviceability, increased maintenance costs, and structural durability. To counter these issues, Fibre Polymer bars have emerged another possibility material for bars. FRP anti-corrosive, high...

The flexural behaviour of concrete containing Foamed glass as partial replacement of coarse aggregate is investigated. The coarse aggregate was replaced with 0%, 25%, 50%, 75% and 100% Foamed glass. All other constituents were maintained the same. Reinforced concrete beams were cast using 2 bars of 8mm in diameter in the tensile zone. The density and compressive strength of concrete decreased a...

Due to creep characteristics of wood, long-term loading can cause a significant stress loss steel bars in reinforced glulam beams and high deflection the beam midspan. In this study, 15 were subjected 90-day test, effects value, reinforcement ratio prestress level on bars, midspan deflection, other parameters compared analyzed. The main conclusions drawn from study that accounted for 22.5%, 20....

To determine whether vision with obliquely incident light is degraded by contrast losses originating in the retina, laser interference fringe patterns were produced on the retina for various directions of incidence of the two interfering beams. Contrast-modulation flicker [Vision Res. 38, 985 (1998)] was used as a psychophysical measure of contrast at the level of the photoreceptors. Fringe con...

Composite couple beams are the concrete elements consisting of longitudinal bars and steel plate, therefore suitable for shear transferring in couple shear walls with arranged gates in its height. In this paper, after modeling couple beams with and without steel plates with F.E methods and calibration the models with experimental results, effects of parameters such as thickness, height, length ...

cracked and un-cracked brazilian disc specimens subjected to diametral compression were used for conducting fracture toughness and tensile strength experiments on a polymer concrete (pc) material. the value of mode i fracture toughness (kic) was determined from the center- cracked brazilian disc and the indirect tensile strength (σt) was obtained from the un-cracked brazilian disc specimen. the...
