Z thickness of steps usually is a geometric parameter of the material e g. The risers are 16 cm and goings are 30 cm.

Hello i am a recent graduate structural engineer and i am given a task to design a steel staircase in the philadelphia region. Design a straight flight staircase in a residential building that is supported on reinforced concrete walls 1 5 m apart center to center on both sides and carries a live load of 300 kg m 2. Though the treads may be supported many other ways. Stringer or string the structural member that supports the treads.

There are typically two stringers one on either side of the stairs. It does not include for example cables ladders chutes grating stairs catwalks handrails or ornamental metal. X width of the opening total run depends on how much space you can allocate in your house for the staircase. Traditionally the staircase is a term for stairs accompanied by walls but contemporary usage includes the stairs alone.

Structural steel the structural elements that make up the frame that are essential to supporting the design loads e g. Beams columns braces plate trusses and fasteners. W staircase width. The stringers are notched so that the risers and treads fit into them.

Staircase series or flight of steps between two floors. A staircase is defined as set of steps from one floor to another floor or combination of riser and tread to make easy transportation from one floor to another floor in a building. I know the type of loads and where to apply them so i can figure out the stringer and landing beam sizes. Y the height of the opening total rise usually determined by the distance between the floors in your house.
