Presentation Objectives

According to the learning goals, which task directly checks recall of basic terminology in stair construction?

• Define the term stair

• Design a new staircase layout for a building

• Calculate live load on a stair flight

• Develop a maintenance plan for a public staircase

Which pair of stair types are explicitly identified for comparison and contrast in the objectives?

• Straight flight and winder

• Dog legged and quarter turn

• String beam stairs and cranked slab stairs

• Cantilever and winder

Which statement best defines stairs in a building context?

• The decorative railing along a corridor

• A set or series of steps (or flights of steps) used to pass from one level or floor to another, typically inside the building

• An enclosed vertical shaft for elevators

• The entire structural space that houses a stairway

In construction terminology, which term refers to the structure containing a stairway?

• Stairs

• Staircase

• Landing

• Ramp

A building requires movement between floors without elevators. Which element provides the series of steps or flights enabling this vertical movement?

• Staircase

• Stairs

• Hallway

• Lift well

Which statement best explains why stairs must have strength and stability?

• To minimize construction costs

• To carry the weight of users and transported items, supporting movement between floors under dead and imposed loads

• To reduce the number of risers required

• To improve the aesthetics of the stairway

According to the material, stairway loads should be related to which factors?

• Architect’s personal preference

• Use and classification of the building

• Local weather conditions

• Availability of materials

Which elements must comply with building regulations for safe stair use?

• Riser, tread, headroom, handrails, and guarding dimensions

• Paint color, finish type, and decorative trims

• Window placements adjacent to stairs

• Lighting fixtures only

A designer is planning a staircase for a hospital where heavy equipment is often transported. Based on the guidance, what should the designer prioritize when specifying the stair?

• Maximizing aesthetic appeal with minimal structural capacity

• Ensuring the stair supports dead and imposed loads and aligning stairway loads with the building’s use and classification

• Reducing headroom to save space

• Eliminating handrails to increase width

Which statement best describes the primary fire safety function of stairs in buildings?

• To provide aesthetic appeal within the building

• To act as the principal means of escape to the outside during fires

• To support the structural load of upper floors

• To serve as ventilation shafts for smoke removal
