Reinforced Concrete Stair.
At wood stair need treatment / conservancy utilize its
resilience. At reinforced concrete stair do not needed.
Reinforced concrete stair weight big enough by it self, hence
in the plan its construction require to get attention and
also labored can be made to economize usage of

Slab less tread Riser Stair
Stair which is its construction is supported by plates of
tread (Aantrede) also riser (Optrede).
So tread and riser is structural construction. At other stair
type, and tread and riser represent construction which
non structural. While structural is plate and its log

Reinforced concrete stair can be made by all kinds of
form depended mould form / its of him.
For arrange in steps return / stair with bordes 180, its
structure form can be made like :
Stair above 3 fulcrums.
Stair above 2 fulcrums.
Float stair ( there is no fulcrums at bordes and wall )

Stair become militant with stepping of wood.
• For this stair as structure use profile logs at ordinary stair
Example :
• Stair by 2 profile log as its structure
