“…Bridge Analysing Program at the Cambridge University [7] for assessing the reserve strength in bridges is suggestive of its applicability for practical design reasons. Ali K. Hussein et al [8] investigated the response of a posttensioned bi-directional slab to bending using various tendon configurations. Nineteen distinct post-tensioned concrete slab models were the subject of a parametric analysis, which revealed that the load-bearing capability of slab with tendons inserted in two directions is higher than that in which tendons inserted in uni direction in slab.…”

Yield line analysis is a powerful method used in structural engineering to evaluate the ultimate load-carrying capacity and failure mechanisms of reinforced concrete slabs. in this study finite element method is used to analyze three side supported(fixed) slab with concentrated loading on different location to find yield line pattern of slab. The finite element software Ansys is used to analysis the slab. this study performed on total five model or specimens. concentrated loading is positioned as-in centre of slab, shifted along central-line along the length, shifted along central-line transverse to the length. ANSYS R2 is used to simulate and analyse the structural behaviour of different models. The analysis aimed to define the yield line pattern and compare the behavior of slab for different loading condition. Overall the objective of study structural behaviour and to find the yield line pattern of slab subjected to concentrated loading at different locations.

The analysis and design of reinforced concrete slabs supported on 3-sides in masonry or reinforced concrete construction involve analytical formulations. In published analytical formulations, orthotropic coefficients and continuity factors are unknown parameters. To obtain moment carrying capacity of the slabs using available formulations, these factors must be required. In this research work, these orthotropic coefficients and continuity factors are presented for transverse loaded RC rectangular slabs supported on three sides under uniform area loading at top face of the slab. These coefficients were obtained using FEA (Finite element Analysis) based Structural Analysis Program (SAP) software. It is also validated with FEA (Finite element Analysis) based SCIA Engineer software and published formulations. It have been observed that obtained results are well comparable with published literature and FEM based software. Results presented in this research paper are conducive to predict the moment-field of the reinforced concrete rectangular slabs supported on three sides having one edge is unsupported. These coefficients will be very helpful for structural designers dealing with reinforced concrete slabs supported on three sides.

The design of reinforced concrete slabs supported on two adjacent edges involves complex formulations. In this paper, a simplistic approach is presented for designing orthotropic slabs supported on two adjacent edges. Slab supported on two adjacent edges (existing slab) is transformed into a slab supported on three edges (equivalent slab) by taking a mirror image of the yield line pattern of two adjacent edges supported RC slabs about its unsupported edges to get the exact collapse mechanism for the slabs supported on three edges. The equivalent aspect ratio can be used in the equations already developed for the slabs supported on three sides. Ultimate moment carrying capacity of the slab carrying uniform load can be evaluated by using the available analytical formulations of the slab supported on three edges. So, the present approach gives a simplified method to analyse and design the orthotropic RC rectangular slab supported on two adjacent edges using the equations available for slab supported on three adjacent edges. Hence, the simplistic approach will be very helpful for structural designers dealing with analysis and design of slabs supported on two adjacent edges. Doi: 10.28991/cej-2020-03091598 Full Text: PDF
