pyStructuralAnalysis

A collection of Python notebooks and scripts for structural analysis calculations using symbolic computation and numerical methods.

Features

• autoimport.py: Common imports and functionality (numpy, matplotlib, sympy, pint)
• Notebooks: Interactive Jupyter notebooks for structural analysis
• Scripts: Python scripts for specific analysis tasks
• Examples: Simple examples to get started

Installation

pip install -r requirements.txt

Quick Start

Using autoimport in scripts

# Add to path and import common functionality
import sys
import os
sys.path.append(os.path.dirname(os.path.dirname(os.path.abspath(__file__))))
from autoimport import import_all
import_all()

# Now you have access to: np, plt, sp, ureg, and common structural symbols
print(f"Beam length: {L}")
deflection = P * L**3 / (48 * E * I)

Using autoimport in notebooks

# In a Jupyter notebook cell
import sys
sys.path.append("..")
from autoimport import import_all
import_all()

Available Symbols

The autoimport module provides these commonly used structural analysis symbols:

• Geometric: x, y, z, L, a, b, h
• Material properties: E, G, nu (Young's modulus, shear modulus, Poisson's ratio)
• Section properties: I, A, J (moment of inertia, area, torsional constant)
• Loads and reactions: P, q, M, R_A, R_B, M_A, M_B
