A beam is one – dimensional (normally horizontal) member, which provides support to the slab and the vertical walls. Bending and shear are predominant in beams.
- For a simply supported beam, effective span shall be taken as a clear span plus effective depth or the distance between the centers of bearing whichever is less.
- In the case of the continuous beam if the width of support less than one by twelve of clear span the effective span.
- If the supports are wider than one by twelfth of the clear span or 600mm whichever is less then effective span
- For end span with one end fixed other end continuous or for intermediate span, the effective span shall be the clear span between the supports.
- For end span with one end free and other ends continuous, the effective span shall be equal to the clear span plus if the width of the continuous support whichever is less.
