trussme

trussme is a Python library for building, analyzing, and optimizing truss structures.

Installation

trussme supports Python 3.10 and newer.

pip install trussme

The package depends on numpy, scipy, pandas, matplotlib, and tabulate at runtime.

Quick Start

import trussme

truss = trussme.Truss()
pin = truss.add_pinned_joint([0.0, 0.0, 0.0])
free = truss.add_free_joint([2.5, 2.5, 0.0])
roller = truss.add_roller_joint([5.0, 0.0, 0.0])

truss.add_member(pin, free)
truss.add_member(pin, roller)
truss.add_member(roller, free)

truss.add_out_of_plane_support("z")
truss.set_load(free, [0.0, -10000.0, 0.0])

truss.analyze()

print(truss.fos)
print(truss.mass)

Built-in Materials

Trussme ships with a small library of common engineering materials. Each record includes a source URL citing where the mechanical properties originate.

Custom materials must also provide a provenance source when added to a truss.
