The drawing room in a residence has a size of 4.2m x 6.0m. The floor slab of this room is designed as a two way slab with comers held down. The design yields a slab depth of i40mm. The reinforcement in short span is l&nm dia bars 150mm c/c and in the long span it is 8mm dia bars at 200mm c/c. Assume any other data required and detail the slab showing clearly the cranking of the bars in the slab and the torsional reinforcement at the corners by drawing sectional

A single span RC T:beam and slab culvert has a clear caniage way of 6.8m and foot paths 750mm wide on both sides. The span of the culvert is 6m, the deck slab is 240mm thick. This slab is supported by three beams, one at the centre and other at 3m c/c on either side of the central beam. The rib size of the beams are 400mm x 800mm. The foot path is elevated from the deck slab by 200mm. Pre-cast concrete railing is provided at the edge of the foot path.
