A T-beam floor consists of 15 cm thick RC slab monolithic with 30 cm wide beams. The beams are spaced at 3.5 m centre to centre and their effective span is 6 m as shown in Fig.7.7. If the superimposed load on the slab is 5 kN/m², design an intermediate beam. Use M 20 mix and Fe 250 grade steel. 6000 -300 IA 3500- -3500 3500 3500 PLAN INTERMEDIATE SLAB T-BEAM 150 300 SECTION A -A Fig. 7.7 T-beam floor
