Stairs and Access in Buildings

  • A set of steps leading from one floor to another, providing a means of communication between floors.

Characteristics of Stairs

  • A staircase is a set of steps arranged in series and placed in an enclosure.
  • Essential requirements of a good stair include safety, fire protection, and durability.
  • Stairs should be designed to provide proper ventilation, natural light, and location (near main entrance for public buildings and centrally for easy access and privacy in residential buildings).

Components of a Stair

  • A step consists of a tread and a riser.
  • Tread: the horizontal portion of a step, which should be wide enough to provide safe passage (e.g., minimum 30cm for public buildings).
  • Riser: the vertical portion of a step, with a typical height of 15cm for public buildings.
  • Nosing: the projecting part of the tread beyond the face of the riser.
  • Flight: a continuous set of steps between floors and/or landings.
  • Baluster: a vertical member that supports the handrail.
  • Balustrade: the combined framework of hand rail and baluster.
  • String or stringer: a structural member that supports the steps and acts as an inclined beam.
  • Run: the total length of stairs in a horizontal plane, including landings.
