Development of Moment Coefficients For Two Adjacent Side Supported Slab By Using Yield Line Theory

Abstract

The slab is a key and generally used structural component. The shape, arrangement, and stiffness of the supporting beams all have a significant role in the slab's performance.IS 456:2000 coefficients are only applicable to rectangular slabs with four non-yielding side supports. But due to architectural requirements, structural engineers are now confronted with a variety of complications, such as slabs supported on two adjacent sides. In the past analytical model was suggested for slab supported over two adjacent edges carrying uniformly distributed area load but design aids were not prepared. The analytical model presented herein to analyze two adjacent edges supported slab carrying uniformly distributed area load on its top edge using yield line analysis. It is also validated with well-established literature. Design aids are also prepared and validated with FE nonlinear analysis in software ATENA and the results are in favour.
