DIFFERENTIATION, USE AND APPLICATION OF S HELL ELEMENTS, MEMBRANE ELEMENTS, T HICK SHELLELEMENTS I N CASE OF HIGHRISE BUILDINGS

This paper present the usage of shell and membrane elements are studied in high rise buildings using latest softwar e ETABS 2013 .using this software results are compared between shell elements and membrane elements. Analysis is done using ETABS software on a high rise building with (2B+18) the building which is suited in earthquake zone IV. The study include lateral di splacement , storey drift and base shear with respect to RCC section.In high rise buildings the application of shell elements and membrane elements are mostly used in shear walls, shear core which acts as lateral stiffeners in high rise buildings and membr ane elements are used in slabs. In certain cases shell elements are also used in slabs because the transfer of loads from slab in membrane is more when compared to shell elements.Thus the shell elements give less moment which result in less reinforcements and makes structures economical.
