How to create the design of the dog-legged staircase

There exist three primary components in a standard staircase which range from stringers, treads and risers. Stringers, generally cut from 2 x 12s, belong to the sloped boards which provide support to the other elements and bear the weight of people walking on the stairs. They're usually arranged 16 in. on center. While going to find out the width of a staircase, keep in mind that width should be wider because wide staircases are more convenient and securer to walk on.

Treads build up the top surface of every step, and risers are set up directly below the front lip of each tread. There are not risers in some stairs, but it is not recommended as risers safeguard the uncovered endgrain of the jagged stringers from the weather.

The staircase should be designed in an efficient manner to bear specific loads, which are identical to those applied for the design of floor.

Stairs made with various materials:

Timber Stairs: these stairs are lightweight and can be smoothly built up, but they contain very low fire resistance capacity. They are mostly suited for small rise residential buildings. Often, fire resisting hard wood of proper thickness are applied.

Stone Stairs: These can be mostly found at areas where ashlar stone is obtainable quickly. Stone stairs are very durable and inflexible, although they are very weighty. Stone utilized for building up these types of stairs should be solid, strong and unyielding to tire.

Brick Stairs: These are generally found at the entrance. Though, brick stairs of single straight flight are frequently made in village houses. The stairs contain either solid wall, or there are arched openings left for acquiring storage space.

METAL STAIRS: Stairs made of mild steel or cast iron are applied only as emergency stairs. They are very durable and resistant against fire. These are mostly found in factories, godowns, workshops, etc.
