Reinforced Brickwork
Definition. Reinforced brickwork (abbreviation R.B.) is a composite structural material consisting of load-bearing brickwork masonry into which lengths of suitable metal (normally steel) are introduced and so bonded as to render the resultant composite capable of resisting not only the compressive stresses but also the tensile and shear stresses which obtain in a structure. It follows from this definition that not only may individual structural members, such as walls, columns and simple, continuous and cantilever beams and slabs be rationally designed and constructed in reinforced brickwork, but that those bonded assemblages of such members normally designated "framed structures," may also be so designed and constructed. Conrad W. Hamann .
Brick work strengthened by introduction of mild steel flats, hoop iron, expanded mesh or bars is termed as reinforced brick masonry. This reinforced brick masonry is capable of resisting both compressive as well as tensile and shear stress. On account of its ability to resist lateral forces, reinforced brick masonry is extensively used in seismic areas. It is essential to use first class bricks (having crushing strength of 140 kg/sq. cm or more) and rich and dense cement mortar in the reinforced brick work. The reinforcement should be effectively bedded and surrounded with mortar cover of 15 to 25 cm. This is necessary to protect the reinforcement against corrosion.
