Nearly half of these injuries are serious enough to require time off the job--11,570 lost workday injuries and 13,312 non-lost workday injuries occur annually due to falls from stairways and ladders used in construction. The value for the Actual Riser Height property changes to accommodate the stair height change. Unit run is the horizontal measurement of from the front to the back of a single stair, which is known as the "tread." Perhaps more important than overall stair width are the proportions of each individual stair (all stairs within a single staircase should be uniform in dimension, of course). The stair tread is the surface area of each step within the stair assembly.

In doing so, we shall calculate the dimensions of the steps and the staircase. as well as examples of using trigonometric functions such as tangent. A minimum width between handrails of 1000mm. For the going dimensions, the minimum is at 215 mm while the maximum is at 355 mm. Deviations in riser height were shown to be more difficult for users. [26] >Steps and Stairways, Cleo Baldon & Ib Melchior, Rizzoli, 1989. Regulated by building codes, stair details specify the sizes of risers and treads, stair widths, the placement of handrails and guardrails, and construction methods for fabricating stairs. Standard code requires that each stair tread fall between 9 inches and 11 inches (22.9 cm and 27.9 cm) to allow people to safely ascend and descend stairs. Calculate stair rise, run, stringers, head-room and upper floor opening dimensions - Wood and concrete stairs - Inch.
