For this table, if a stair does not satisfy all three conditions of stair width, riser height, and tread width (in this case, the conditions need to be false), the stair violates the requirement. Note that this table contains an “E” rule column representing the else rule (similarly, columns 5 through 10 in Table 1.3 can be replaced with an ...

No stair tread can be smaller than 250mm and no riser can be higher than 200mm. One of the problems is to get the treads and the risers to all be the same in the space given and to have them work out so that there is a minimum amount of cuts involved.

Multiply the riser amount (13) by the tread size that corresponds ie If you divide by a 184mm riser, then the tread is 250mm, If divide by 170mm, then the tread is 300mm. eg 13 * 250mm = 3250mm (You must therefore have 3250mm horizontal distance available for the staircase to fit)

Students will adapt stair calculations to determine the number of stairs, landing height, stair tread, and riser dimensions. In addition to measuring skills, mathematical principles, and stair and handrail fabrication and assembly, the course covers installation techniques required for circular and u-shaped stair configurations.

Check that all treads are level and secure. Riser heights and tread depths should be, respectively, as uniform as possible. As a guide, stairs in new residential buildings must have a maximum riser of 7-3/4 inches and a minimum tread of 10 inches. Inspect the condition and fastening of all stair coverings. Reattach any stair covering that is loose.

Assume we are using 7” as the riser height. Mark each division on the y-axis in increments of 7, and the x- axis will be in increments of 11. Starting at 11 on the x- axis draw a vertical line going up 1 division on the paper to represent a rise of seven inches. Then draw a horizontal line I division to the right to represent a tread of 11 ...
