Structural wall panels often experience eccentric loads due to a range of loading conditions including: corbel elements applied to the wall, imperfections in construction, uneven loading conditions on top of the wall and temporary loading during operation and/or maintenance. Openings in these walls are frequently required as a result of changes to a buildings function, architectural or mechanical necessities. This is typically for the provision of doors and windows or for services including ventilation and air-conditioning ducts. In recent years, strengthening and retrofitting of structural members using bonded Carbon Fibre Reinforced Polymer (CFRP) materials has gained a great deal of attention. The superior properties of composite materials, including: high elastic modulus, high strengths, light weight as well as excellent durability, have made them a suitable alternative for steel plates in strengthening applications. Experimental tests have been undertaken on RC opening walls supported by two types of restraint conditions with and without FRP strengthening. The study found that walls with CFRP greatly change the ultimate capacity of the walls under various support conditions.
