There are three types of load. These are;

Point load is that load which acts over a small distance. Because of concentration over small distance this load can may be considered as acting on a point. Point load is denoted by P and symbol of point load is arrow heading downward (↓).

Distributed load is that acts over a considerable length or you can say “over a length which is measurable. Distributed load is measured as per unit length.

### Example

If a 10k/ft load is acting on a beam having length 10′. Then it can be read as “ten kips of load is acting per foot”. If it is 10′ then total point load acting is 100Kips over the length.

1. Distributed load is further divided into two types.

Uniformly distributed load is that whose magnitude remains uniform throughout the length. For Example: If 10k/ft load is acting on a beam whose length is 15ft. Then 10k/ft is acting throughout the length of 15ft.

Uniformly distributed load is usually represented by W and is pronounced as intensity of udl over the beam, slab etc.

Conversion of uniform distributed load to point load is very simple. By simply multiplying the intensity of udl with its loading length.  The answer will be the point load which can also be pronounced as Equivalent concentrated load (E.C.L). Concentric because converted load will acts at the center of span length.

Mathematically, it can be write as;

Uniformly varying load is further divided into two types;
