Repairing and Strengthening of Damaged RC Columns Using Thin Concrete Jacketing

retrofitting of reinforced concrete columns using steel and concrete jacketing tchnique

retrofitting structures is an important issue. structural weakness may be due to changes in design codes or defects in implementation. adding structural floors to the existing structures may also lead to the need for strengthening and retrofitting. retrofitting is possible before the earthquake or may take place as rehabilitation of damaged members after earthquake. elements such as columns 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...

FRP Composites Strengthening of Concrete Columns under Various Loading Conditions

This paper provides a review of some of the progress in the area of fiber reinforced polymers (FRP)-strengthening of columns for several loading scenarios including impact load. The addition of FRP materials to upgrade deficiencies or to strengthen structural components can save lives by preventing collapse, reduce the damage to infrastructure, and the need for their costly replacement. The ret...

Strengthening Of RC Beam Using GFRP Wraps

Fiber reinforced polymer materials are continuing to show great promise for using strengthening reinforced concrete structures. These materials are an excellent option for use as external reinforcing, because of their light weight, resistant to corrosion and high strength. The main aim of this study is to investigate the flexural characteristic of RC beams using GFRP sheets and strips. This pap...
