Axial Compressive Strength of Reinforced Concrete Columns Wrapped with Fiber Reinforced Polymers (FRP)

Influence of Temperature and Moisture on the Compressive Strength of Carbon Fiber Reinforced Polymers

The effect of moisture absorption and high temperature on the compressive strength of unidirectional IM7/977-2 carbon/epoxy resins have been investigated experimentally. The specimens were divided into 4 groups, and tested under 4 different conditions by varying the testing temperature and moisture parameters. The fiber orientation selected were 0o, ±45o and 90o...

Strengthening of Concrete and Masonry Structures with Fiber Reinforced Polymers (frp)

Since the late 1980s, the civil engineering community has become interested in the application of Fiber Reinforced Polymers (FRP) to the construction industry. These materials are comprised of very strong fibers and a resin matrix. The most popular application of FRPs has been in repair and rehabilitation of structures. In this technique, FRPs are bonded to the exterior surface of the structura...

Rehabilitation of Reinforced Concrete Columns

In recent years, rehabilitation has been the subject of extensive research due to increased spending on building work and repair of built works. In all cases, it is absolutely essential to carry out methods of strengthening or repair of structural elements, and that following an inspection analysis and methodology of a correct diagnosis. The reinforced concrete columns are important elements in...

Residual strength of blast damaged reinforced concrete columns

Columns are the key load-bearing elements in frame structures and exterior columns are probably the most vulnerable structural components to terrorist attacks. Column failure is normally the primary cause of progressive failure in frame structures. A high-fidelity physicsbased computer program, LS-DYNA was utilized in this study to provide numerical simulations of the dynamic responses and resi...

Behavior of FRP-Confined Reactive Powder Concrete Columns under Eccentric Loading

Fiber reinforced Polymers (FRP) have widely used for the purposes of enhances strength and ductility of concrete columns. Proper design of such hybrid columns, however, requires a better recognition of the behavior of concrete columns confined with FRP. In this paper, the influence of FRP thickness, concrete compressive strength, and column size on the performance of eccentrically loaded reacti...
