bricoleur.stairs module

Function for stair calculations

bricoleur.stairs.number_risers(total_rise: float, max_riser_height: float) → float

Calculate the number of risers (steps) between the upper and lower finish levels.

Parameters:

• total_rise (float) – The vertical distance between the finished flooring of the upper and the lower levels.

• max_riser_height (float) – The maximum riser height (usually from the building code).

Returns:

The number of risers.

Return type:

no_risers

Example

>>> import bricoleur as bric
>>> total_rise_datum = 100
>>> max_riser_height_datum = 7.5
>>> number_risers = bric.number_risers(
>>>     total_rise = total_rise_datum,
>>>     max_riser_height = max_riser_height_datum
>>> )
>>> print(number_risers)
14

bricoleur.stairs.riser_height(total_rise: float, number_risers: int) → float

Calculate the exact riser height.

Parameters:

• total_rise (float) – The vertical distance between the finished flooring of the upper and the lower levels.

• number_risers (int) – The maximum riser height (usually from the building code).

Returns:

The riser height.

Return type:

riser_height

Example

>>> import bricoleur as bric
>>> total_rise_datum = 100
>>> number_risers_datum = 14
>>> riser_height = bric.riser_height(
>>>     total_rise = total_rise_datum,
>>>     number_risers = number_risers_datum
>>> )
>>> print(riser_height)
7.142857142857143

bricoleur.stairs.total_run(number_risers: int, tread_depth: float) → float

Calculate the total run.

Parameters:

• number_risers (int) – The maximum riser height (usually from the building code).

• tread_depth (float) – The depth of the tread.

Returns:

The total run.

Return type:

total_run

Example

>>> import bricoleur as bric
>>> number_risers_datum = 14
>>> tread_depth_datum = 11
>>> riser_height = bric.total_run(
>>>     number_risers = number_risers_datum,
>>>     tread_depth = tread_depth_datum
>>> )
>>> print(total_run)
