Usage

Installation

To use JoistPy, first install it using pip:

pip install joistpy

To access the properties within the library, first import the module.

from joistpy import sji

The library includes all standard K, LH, and DLH joist designations. To access the K-Series joists, for example, use dot notation for the group of designations.

sji.K_Series

From there specific designations can be obtained in a similar manner. Note that the prefix K, LH, or DLH followed by an underscore must be added to the joist designation in order to properly access it via dot notation.

joist = sji.K_Series.K_8K1

Properties can be obtained in a similar manner. Properties that can be accessed include approximate weight in plf and load tables for L/360 deflection criteria and Total Safe Load. Span values are in ft and load table values are in plf.

weight = joist.weight
l360 = joist.l360
total = joist.total

Additonal properties can be calculated by using the Designation class methods.

span = 17.5 # joist span in ft
area = joist.get_eq_area() # equivalent cross-sectional are in in^2
mom_inertia = joist.get_mom_inertia(span) # moment of inertia in in^4
wl360 = joist.get_wl360(span) # load that produced L/360 deflection for the span in plf
