Dasign of T- beam is some what similar to rectangular beam, in design slab thickness is determined first. the slab is acts as compression flange in designing the beam. the flange acts as compression zone, which is balance by steel embeded in the bottom web of the beam.
slab thickness= t, in.
effective depth= d, in.
width of web= b', in.
flange width= b, in.
width of flange should be least of the three alternatives,
1. span/4.
2. b' + 16t.
3. centre to centre spacing of beams.

Let say you have a beam leaning on 4 rocks = are beam 0 are rocks . is the air # are crate of peanut butter This is a system with a continuous beam. The peanut butter crate will make the beam bends downwards between rocks 1 and 2 and the beam between rocks 2 and 3 will bend upwards because of the continuity .............#.......................................................... ======================================..==========..========== 000.................000..................000................000
because the deflection in simple suported beam is more due to the orestriction at the ends as the ends are freely supported by twoo supports
Tee beam, L beam & Inverted beam tayyab.. there are many other types of beam such as cantilever beam , simply supported beam . t beam . knife edge beam and many more
