STRUCTURAL DESIGN, DETAILING AND CONSTRUCTION OF STABLESS REINFORCED CONCRETE STAIRCASES

Theo Ossai on October 8, 2021

Stairs are used to create a pedestrian route between different vertical levels by dividing the height between the levels into manageable steps. For example, stairs connect a ground floor level of a building to the floor above it (first floor) by dividing the height between the levels into manageable steps. Very generally, the word ‘stairs’ refers to a staircase, whereas the word ‘step’ refers to the individual steps that make up the staircase.

Staircases are generally classified as straight stairs and curved stairs. The straight staircase includes various configurations such as a single flight stairs, half turn stairs, single quarter turn stairs, and three quarter turn stairs. The various straight staircase configurations will include elements like flights, landing slabs (half landing, quarter landing or full landing) and sometimes winders.

Winders are steps that are narrower on one side than the other. They are used to change the direction of the stairs without landings. The half landing is found in half turn staircase, the quarter landing is found in found in a single or three turn staircase.
