Structure Analysis Project

This project provides tools to define and analyze 2D structural elements, such as bars and nodes, with detailed mechanical properties and loading capabilities. It also includes a GUI interface for interactive visualization and design.

🏗️ Project Structure

• Structure_Analysis – Core mechanics for node, bar and structure modeling.
• Structure_AnalysisGUI – Graphical interface for building and analyzing structures.
• utils – Helper modules for calculations, material properties, and possibly data input/output handling.

📦 Features

• Define 2D structural bars with rectangular or circular cross-sections.
• Support for solid and hollow sections.
• Assign mechanical properties like material, thickness, and loads.
• Perform geometric and mechanical analysis:
  • Volume
  • Mass
  • Sectional area
  • Moment of inertia
  • Static moment
  • Von Mises stress check for resistance analysis
• Consistency checks (e.g. node overlap, bar length validation).
• Modular design allows defining multiple bars and combining them into structures.
• GUI for visual and interactive structure creation (in Structure_AnalysisGUI).

🔧 Example Usage

from Structure_Analysis import Node, Bar, Structure

# Create nodes
start = Node("A", 0, 0)
end = Node("B", 0, 1000)

# Create a bar
bar = Bar(length=1000, width=100, height=200, hollow=False, section='rectangular', material='steel', alpha=90, start_node=start, end_node=end)
bar.add_load(position=500, fx=0, fy=-1000, m=0)

# Create a structure and add the bar
frame = Structure(name="Simple Frame")
frame.add_bar(bar)

# Print structure info
frame.info()
