This tool analyzes steel beams and columns under axial loads and uniaxial or biaxial bending. The result is a Stress Ratio, which compares the actual stress to the allowable stress. Calculations are based on the American Institute of Steel Construction's Specification for Structural Steel Buildings-Allowable Stress Design and Plastic Design, 1989.

The Steel Beam and Column Designer to AISC 360-89 is an online tool designed to evaluate the performance of steel beams and columns subjected to axial loads and uniaxial or biaxial bending. By calculating the Stress Ratio, this tool compares the actual stress in the structural member to the allowable stress, ensuring compliance with the American Institute of Steel Construction's (AISC) 1989 Specification for Structural Steel Buildings - Allowable Stress Design and Plastic Design.
This tool is for:
- Structural engineers looking for precise stress analysis for beams and columns.
- Design professionals needing to verify designs against AISC 360-89 specifications.
- Engineering students studying the principles of steel design according to historical standards.
This parametric technical document helps users by offering a structured way to assess stress ratios for various load combinations. This approach supports efficient decision-making in both preliminary and final design phases, while ensuring that structural members remain within safe stress limits as per AISC standards.

FAQs
What is the significance of a Stress Ratio in steel design?
The Stress Ratio is a measure of the safety margin in steel design. It compares the actual stress experienced by a steel member under loads to the maximum allowable stress specified by AISC 360-89. A Stress Ratio below 1 indicates that the member is safely designed.
How does AISC 360-89 handle biaxial bending for columns?
AISC 360-89 provides specific guidelines for analyzing steel columns under biaxial bending, where the member is subject to bending around two axes. The interaction of bending moments in both directions is checked to ensure the column meets the allowable stress limits.
Why is it important to consider both axial loads and bending moments in steel beams and columns?
Steel beams and columns often experience a combination of axial loads and bending moments in real-world applications. These combined stresses affect the structural performance, and proper analysis ensures that the member will not fail under complex load scenarios.

How to prepare an engineering report
Engineering reports require a balance of clarity, precision, and professionalism. Here are some best practices for preparing a report we use at CalcTree:
- Clear and visual: Use heading types to establish a logical structure, add diagrams for clarity.
- Integrate sources: Map data from your calculation tools such as spreadsheet or Python to your report.
- Units: Assign units to physical quantities.
- Compliance: State and hyperlink the relevant codes of practices.
- Peer review: Share a link to your page with team members for reviews and feedback.
