Cpst Effective Buildings with Local Bricks

Abstract

Load bearing brickwork can be used in two to three storey buildings eliminating the reinforced concrete framework thus leading to a considerable economy. However, this method of construction is not often used since the locally available bricks are of low quality and hence structural engineers are rather reluctant to promote it. It is shown here that it is possible to achieve a characteristic strength of 1.5 N/mm2 when bricks satisfy certain physical testing criteria. The quality control measures required for such construction are also highlighted. It is also shown that although the use of 1.5 N/mm2 design compressive strength offers satisfactory behaviour with respect to primary effects, further precautions will be required in load bearing brickwork structures to prevent cracking due to stresses of secondary nature.
