If we provide triangular beam in RCC, it is difficult to

1. Place Top Reinforcement

2. Place stirrups

3. Casting

4. Connection of slab to beam

Om Prakash Chhangani

Concrete is good in compression and therefore we make beams wherein compression area is more to take advantage of this phenomenon. Triangular shape is not a good geometry for RCC beams and therefore either rectangular or T beams are preferred.
