👉TYPES OF STAIRS: @engineersWorks
.
▶Depending upon the various arrangement of steps, stairs can be classified under following categories:
1. STRAIGHT STAIR:
In this stair, all the steps are arranged continuously
along in one direction. One flight may be split into
one or more than one flight by interposing a
landing. This stair can be used where narrow and
long space is available for a staircase such as
entrance, porch etc.
2. DOGGED-LEGGED STAIR:
This stair consists of two straight flights of steps
with direct turns between them. This stair is very
useful where the total width of the stair is just twice
the width of the steps.
3. OPEN NEWEL STAIR:
This type of stair consists of two or more flights
arranging a well or opening between the backward
and forward flights. When all the steps are difficult
to arrange in two flights, a short third flight of 3 to
6 steps may be provided along the direction
perpendicular to the hall. Open newel stair is mostly
adopted in the lift.
4. GEOMETRICAL STAIR:
This is another type of open newel stair where the
open well between the forward and the backward
flight is curved. This stair may contain different
geometrical shape. Here the change in direction is
achieved by using winders.
5. CIRCULAR STAIR:
In this type of stair, all the steps radiate from a
newel or well hole, in the form of winders. The
circular stair is adopted at the back side of a
building to access its various floors.
6. SPIRAL STAIR:
Spiral stair is very similar to a circular stair. It
consists of individual steps or treads, connecting to
a centre column. The overall diameter of the stair
may range from 1 to 2.5 m.
7. QUARTER-TURN STAIR:
The quarter-turn stair can be defined as the stairs
that are turned at 90 degrees with the help of level
landing.
8. BIFURCATED STAIR:
This type of stair is provided in modern public
buildings as well as residential buildings. In this
stair, the flight is so arranged that there is a wide
flight at the start which is sub-divided into narrow
flights at the mid-landing. The narrow flights start
from either side of the mid landing.
