DEFLECTION STUDY OF RCC LOAD BEARING WALL AND SLAB

Abstract

This study is made on a residential building which is constructed at Bawana by DSIIDC. The building is a RCC structure in which the slab is cast monolithically with the RCC walls of the building. This type of structure is called load bearing wall and slab structure. The thickness of the slab is 100mm and the thickness of the wall is also 100mm.Due to the use of thin sections, the useable area had increased to a considerable amount. It is a G+3 structure planned for the EWS (economically weaker sections). Each dwelling is a one room set with attached toilet. A door opening was planned in the common wall of the two flats after the full construction. The load test had been performed after the opening was created to study the deflection characteristics of the RCC wall and slab. The deflections were found at different point in the slab and the opening of the RCC wall and is compared with the permissible deflections as per IS 456-2000. It was found that the deflections we get by testing were within the permissible limits. Design of the existing building was also checked numerically by STAADPRO. Numerical study was performed on the two cases, with the opening in common wall and without opening. The stresses in the common RCC wall with and without opening were also compared. The result of both the analysis , experimental and numerical, is compared and to study the deflection characteristics. The detail account of deflection study is discussed in this project work.
