limitstates 0.1.0

A structural design library.

limitstates

A structural design and representation library.

Overview

limitstates is a python library for that can represent and design of structural elements according to code and material standards from various countries. Limit states has two main components: a set of classes that representations structural objects, e.g. A Ibeam that is 6m long made or steel; and design libraries that can act on elements and determine capacities, e.g. Canada's CSA s16 steel material standard.

A simple script is shown below where a structural object is created and used.

import limitstates as ls
import limitstates.design.csa.s16.c24 as s16

L = 6
Fy = 350
sectionName = 'W310X118'

# Define the material, in this case a code specific steel with Fy = 350 MPa
mat = s16.MaterialSteelCsa24(Fy, sUnit='MPa')

# Define a steel section from a database, in this case a cisc 12 w section.
steelSections   = ls.getSteelSections(mat, 'csa', 'cisc_12', 'w')
section         = ls.getByName(steelSections, sectionName)

# make a member, in this case a simplely supported beam 6m long beam.
member = ls.initSimplySupportedMember(L, 'm')

# Make a element, which the design library can act on.
beam = s16.BeamColumnSteelCsa24(member, section)

# Check capacity assuming it's laterally supported using CSA's s16 standard.
Mr = s16.checkBeamMrSupported(beam) / 1000
