Abstract: RC grid floors consist of a set of interconnected beams oriented along two directions in plan and topped with a thin slab.Such floors are fOund to be suitable for comparatively large spans(10-20 m) where the top. surface is required to be flat. Grid floors may be supported on load bearing walls which structurally simulate as simple supports. On the other hand ,floor beams may be framed into a system of spandrel beams located all along the ridges which in turn may interconnect closely spaced RC columns. Such a system of supports simulates as fixed supports. For a given floor plan size (square), it is imperative for the structural designer to select. the most appropriate grid structural elements so that the dead load moments are minimised while satisfying the limit states of deflection, shear and moment for the total load (DL + LL). The parameters between which there is trade-off are web depth and grid spacing for a given type of supports and magnitude of imposed load. Attempts have been made in the present dissertation to study the behaviour of grid floor parameters in the process of selecting the most appropriate grid system fora given floor plan. Square plans of 10 m and 12 m supported on load bearing walls with imposed loading of 3 and 5 kN/m.2 a.rici 15 m and 18 m square plans with grid beams framed-into spandrel beams have been studied for imposed load of 3 and 5 kN/m2. Appropriate conclusions based on analytical results have been drawn.
