Design Of Reinforced Concrete Beams Using Two different Specification

Abstract

Nowadays, reinforced concrete beams are designed using traditional specification, such as BS8110 and Eurocode2 based on truss action. In this research BS8110 and Eurocode2 specification of designing a beam for flexure and shear are studied and compared with each other, to provide an in depth understanding of the two approaches. Two beams are designed, the first beam using BS8110 and the second beam using Eurocode2. The designs based on BS8110 and Eurocode2 at the ultimate and serviceability limit states are discussed and the approach used to predict deflections is described and checked using standard relationship based on statics. Secondly the BS8110 and Eurocode2 approaches to designing a beam for shear and deflection are compared with each other. the two test beams are tested and the test results are compared with predicted results. The results from the laboratory tests have shown that the Eurocode2 beam carried a higher load and gave a higher central deflection compared to BS8110.
