Problem
BS EN 1504-9:2006
BS EN 1504 Principle 4 is concerned with structural strengthening by increasing or restoring the structural load bearing capacity of an element of the concrete structure. It is essential when using this Principle that all stresses associated with a repair and the original or deteriorated structure are considered. Certain systems may impose additional stresses on the repaired structure, resulting in changes in the function of the original structure.
Solution
BS EN 1504-3, BS EN 1504-4 & BS EN 1504-5
BS EN 1504-3: Structural and non-structural repair
BS EN 1504-4: Structural bonding
BS EN 1504-5: Concrete injection
Methods of protection based upon the BS EN 1504 Principle 4 is the use of the following:
-
4.1 Adding or replacing emedded or external reinforcing steel bars.
-
4.2 Installing bonded rebars.
-
4.3 Plate bonding.
-
4.4 Adding mortar or concrete.
-
4.5 Injecting cracks or voids.
-
4.6 Filling cracks or voids.
-
4.7 Prestressing.
