## What is the main difference between rectangular beam and T-beam?

These beams are very efficient because the slab portion carries the compressive loads and the reinforcing bars placed at the bottom of the stem carry the tension. A T-beam typically has a narrower stem than an ordinary rectangular beam. These stems are typically spaced from 4′-0” apart to more than 12′-0”.

What is effective T-beam width?

A. 4: Effective width is an imaginary width of the flange over which the compressive stress is assumed to be uniform to give the same compressive force as it would have been in case of the actual width with the true variation of compressive stress (Fig. 5.10. 4 of text).

### How Do You Measure T-beam depth?

For continuous beams and frames may be assumed as 0.7 times the effective span. The depth of the neutral axis is determined by equating the moment of area of concrete in compression to the moment of equivalent area of steel in tension.

Which is stronger T-beam or rectangular beam?

T-beam is simply rectangular beam cast monolithically with the slab. T-beam casting with slab as we know so Its flange takes compressive stress and that mean It will resist more sagging moment of beam. Depth of beam is reduced as compare to ordinary beam so better headroom advantage.

#### What is TB in beam?

TB stands for Tie Beam.

What is the effective width?

The “effective width” method provides an approximation to the complex non- uniform stress distribution in a thin buckled plate under compression. The ultimate load is reached when these edge stresses, carried by the “effective width”, exceed the yield stress of the plate material.

## What are the advantages of T-beam?

Flanges are more effective in resisting bending stresses while the Web is more resistive in shear stresses. 2- The T-beam has separate parts for resisting both bending and shear forces as a result very good in resisting stresses as compared to ordinary rectangular beams in buildings and bridges.

What is effective depth in beam?

Effective depth of the beam and slab is the distance between extreme compressive concrete fibre to the centroid of tension reinforcement in section under flexural condition. And in another words it is described as distance from the centroid of tension Steel to theoutermost face of compression fibre.

### What is the maximum size of beam?

The maximum beam size is 1016x305x487ub and the maximum span is 75m. If you space the beams 3m apart and have a small snow load on top, you can do this.

What is the disadvantage of T beam?

1. There is a considerable increase in the shear stress at the junction of the flange and the web of the beam due to the change in cross section. Since the beam slab is monolithic (rigid), it becomes very weak in resisting lateral shear forces. …
