To obtain moment carrying capacity of the slabs using available formulations, these factors must be required. In published analytical formulations, orthotropic coefficients and continuity factors are unknown parameters. The analysis and design of reinforced concrete slabs supported on 3-sides in masonry or reinforced concrete construction involve analytical formulations. The results obtained from the analytical model were represented in the form of design aids to help find the moment field which are easy to use and useful for designing such slabs rather using complex equations. The modelling in ATENA is done for different aspect ratios (1.0, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, and 2.0) and it is observed that actual capacity of slabs was greater than the design load considered for all cases. ATENA is used for FE modelling of RC structures.
The results obtained from this analytical model were validated with available formulation.Īlso, the proposed models were validated with ATENA 3D V5.1. To analyse such slabs, analytical modelling of 3-sided supported RC rectangular slabs carrying uniform area loading is carried out with different support conditions (Three edge discontinuous slab, three edge continuous slab, parallel supported edge continuous slab, parallel supported edge discontinuous slab and two adjacent edge discontinuous slab with one edge free). In design codes, moment coefficients for various end conditions of slabs are given but these are limited up to the slabs supported on their four sides however, in routine purposes sometimes, designers encounter the problem having three sides supported slabs, for which moment coefficients are not as such given. RC slabs are the most widely constructed structural element in RC construction across the world.
