A stair flight is a run of stairs or steps between landings. A stairwell is a compartment extending vertically through a building in which stairs are placed. A stair hall is the stairs, landings, hallways, or other portions of the public hall through which it is necessary to pass when going from the entrance floor to the other floors of a building.
A dog-leg staircase A quarter-landing, on a dog-leg staircase, is made into an architectural feature, by the use of arches, vaulting and stained glass. 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.

A grid deck uses beams and diaphragms as the supporting structure. The supporting system of a grid deck is analyzed using a grillage analysis. A slab deck is one where the deck is analyzed as a plate. If the slab has a stiffness that is different in two directions (at right angles), then the deck is known and analyzed as an orthotropic deck.
In between the posts, two 2x4s are attached to the posts with screws for the best connection. The lower board is placed 3.5" from the top of the finish deck to the bottom of the board. The top board is placed with the top at 35" from the deck. Then the vertical 2x2 pressure treated wood balusters are installed spaced regularly every 3.5". Then ...
In engineering, a longeron or stringer is a load-bearing component of a framework. The term is commonly used in connection with aircraft fuselages and automobile chassis . Longerons are used in conjunction with stringers to form structural frameworks.
The plate assemblies are fabricated off site, and welded together on-site to form steel walls connected by stringers. The walls become the form into which concrete is poured. Steel plate construction speeds reinforced concrete construction by cutting out the time-consuming on-site manual steps of tying rebar and building forms.
When not being used, the ladder is stowed away, usually rolled up, rather than left hanging. On late 19th-century warships, this kind of ladder would replace the normal fixed ladders on deck during battle. Fixes ladders, and railings, would be removed and replaced with Jacob's ladders and ropes in preparation for battle.
Isogrid is a type of partially hollowed-out structure formed usually from a single metal plate with integral triangular stiffening stringers. It was patented by McDonnell Douglas (now part of Boeing) in 1975. [1] [2] Isogrids are extremely light and stiff. [3]
