2 Rise Straight Gooseneck with Tandem Cap
On a Dadoed Stringer , how deep the is the dado

Tandem Cap
Fillets are where in a stair system
shaped to fit between balusters under the handrail and on top of buttress cap

Notched stringer
A balusters must have max opening between of opening?

100mm
A primary stairway between each floor in a dwelling unit must have a minimum between wall of faces what’s that distance
860 mm
A semi-housed or planted stringer has two parts:
A cut out stringer and a plain stringer. The plain stringer is a finished piece of wood attached to the wall. The cut out stringer is laminated to the plain stringer. The treads and the risers butt into the finished plain stringer.
a starting newel should
be extended into the flooring system, use dry material

anchorage
important to anchor posts securely in place. to support weight of people always grabbing them, starting newel should be extended through floor and securely blocked
Are handrails required when there’s only two risers within a dwelling unit
No
Balusters
small uprights under the handrail that close in the open side of the stairs for safety
building code requires balusters to be spaced such that a 4” diameter object cannot fit through it.

balustrade
complete unit of newel posts, handrail, balusters and buttress cap used to protect open side of staircases
buttress or string cap
used under balusters also called shoe rails or base rails
shaped to take the end of the baluster and are used in railings at the landings or on top of the stringers.
calculate stairwell rough opening
RO = run/rise x (headroom+floorthickness) + 75mm
Calculating stringer length
three methods
- multiply unit of bridge by number of treads
- multiply unit of bridge by number of rises
- number of linerier feet of stringer is equal to the number of treads (allow extra foot)
Calculating actual Rise
take total number of risers and divid by the total rise
Ex 2650/15=176.67mm or 177
Calculating run
using proportion rules the run can be calculated
- rise plus run = 450mm
rise= 177
177 + X=450
X=450-177
X(run)= 273mm
