A dog-leg is a configuration of stairs between two floors of a building, often a domestic building, in which a flight of stairs ascends to a quarter-landing before turning at a right angle and continuing upwards. [1] The flights do not have to be equal, and frequently are not.

Structurally, the flights of a dog-leg stair are usually supported by the quarter-landing, which spans the adjoining flank walls.

From the design point of view, the main advantages of a dog-leg stair are:

Stairs Construction designed to bridge a large vertical distance by dividing it into steps

Stairs is a structure designed to bridge a large vertical distance by dividing it into smaller vertical distances, called steps. Stairs may be straight, round, or may consist of two or more straight pieces connected at angles.

A newel, also called a central pole or support column, is the central supporting pillar of a staircase. It can also refer to an upright post that supports and/or terminates the handrail of a stair banister. In stairs having straight flights it is the principal post at the foot of the staircase, but the term can also be used for the intermediate posts on landings and at the top of a staircase. Although its primary purpose is structural, newels have long been adorned with decorative trim and designed in different architectural styles.

Airstair

An airstair is a set of steps built into an aircraft so that passengers may board and alight the aircraft. The stairs are often built into a clamshell-style door on the aircraft. Airstairs eliminate the need for passengers to use a mobile stairway or jetway to board or exit the aircraft, providing more independence from ground services. Some of the earliest aircraft to feature airstairs were the Martin 2-0-2 and Martin 4-0-4. Some models of the Douglas DC-3 were also retrofitted with airstairs. As airport infrastructure has developed, the need for airstairs has decreased, as jetways or mobile stairways are often available.

Winecoff Hotel fire 1946 fire in downtown Atlanta, Georgia, United States; deadliest fire in US history

The Winecoff Hotel fire of December 7, 1946, was the deadliest hotel fire in United States history, killing 119 hotel occupants, including the hotel's original owners.
