Abstract
The principle objective of this paper is to demonstrate the strength in lintels that can be achieved by using expanded metal reinforcement instead of the conventional steel reinforcement. Lintel is an important structural member provided over openings to transfer the load of masonry over opening. Normally structural design of lintel is ignored and bars of 8mm, 10 mm or even 12mm diameter are used with varying lintel depth of 100mm to 200mm. Considering load carrying capacities of such lintels it observed that materials are not fully utilized. This results in excessive use of materials and resources which in turn results in exploitation of economy. Considering huge materials involved in lintels in multistoried buildings, there is a need to achieve economy in this area. The use of unnecessary steel reinforcement can be avoided by using a innovative material called Expanded Metal Reinforcement (EMR) for economy in materials and fabrication cost. Therefore, an experimental program is undertaken to determine structural behavior lintels using EMR. The work includes comparison of flexural resistance, deflection, and cost of lintels using EMR with unreinforced and conventional lintel.
