In this research, using the results of 6 tests, the effect of Carbon Fiber Reinforced Polymer (CFRP) sheets on the behavior of reinforced concrete coupling beams of shear walls is studied. First, in the experimental part of the study, four coupling beams with different reinforcements were manufactured and tested. Then, after the failure of the specimens, two of them were rehabilitated and stren...

The article defines the main results for development of reinforced concrete mechanics. In isotropic medium between cracks is used "first object - flows-blocks", "second cracks" and effect concrete, physical essence which non-uniformity continuous reinforcement. Reactions arise in deformation reinforcement from bonding compressed tensile region. average resistance "average total force working re...

Strengthening of flat slab-column connections to resist imposed lateral drifts is often required for older reinforced concrete structures in which the slabs were typically designed gravity load only or have been less stringent requirements. The complex stress state around columns means that strong experimental evidence repair and strengthening techniques be adopted with confidence practice. Alt...

in this paper, the effect of cyclic loading on punching strength of flat slabs strengthened with carbon fiber reinforced polymer (cfrp) sheets is studied. experimental results of ten slab specimens under monotonic and cyclic loading are analyzed. eight specimens were strengthened with cfrp sheets on the tensile face of the slabs and the two other specimens were kept un-strengthened as control s...

corrosion of steel reinforcement is one of the most prevalent causes of reinforced concrete (rc) structures deterioration in chloride-contaminated environments. as a result, evaluating the impact of any possible corrosion-induced damages to reinforced concrete bridges strongly affects management decisions: such as inspection, maintenance and repair actions. the corrosion propagation phase is a ...

Concrete track slab and asphalt trackbed are being introduced in Korea for providing good bearing capacity, durability to the track and comfortable rideness to passengers. Such a railway system has been designed by the train load so as to ensure stability. But there is lack of research and design for temperature changes which influence the behavior characteristics of concrete and asphalt. There...

Abstract This report examines the behavior of a reinforced concrete slab, part an experimental structure, under loads derived from casting formwork system subsequent plate and laid mix in slab above it. The deflections individual stages were measured with help dial gauges. full strength deformation characteristics concretes used construction researched. at all loading was studied, including eac...

The Laramide orogeny is the Late Cretaceous to Palaeocene (80^55 Ma) orogenic event that gave rise to the Rocky Mountain fold and thrust belt in Canada, the Laramide block uplifts in the USA, and the Sierra Madre Oriental fold and thrust belt in Mexico. The leading model for driving Laramide orogenesis in the USA is flat-slab subduction, whereby stress coupling of a subhorizontal oceanic slab t...

Fibre-reinforced polymer (FRP) rebars are being increasingly used to reinforce concrete structures that require long-term resistance a corrosive environment. This study presents structural performance of large scale two-way slabs reinforced with FRP rebars, and their performances were compared against conventional steel concrete. Both carbon (CFRP) basalt (BFRP) considered as replacement. Exper...
