About this calculator
Moment of Inertia: Rectangular Hollow Sections - SHS/RHS is a specialized online tool designed to calculate the moment of inertia for Square Hollow Sections (SHS) and Rectangular Hollow Sections (RHS). Simply input the height, width, and thickness of your section to get results for structural analysis and design.
This calculator is for:
- Structural Engineers: Quickly determine the moment of inertia for SHS and RHS sections during design or feasibility checks.
- Architects: Understand structural properties to integrate aesthetic and functional design elements.
- Engineering Students: Learn and verify moment of inertia calculations for hollow sections as part of coursework or research.
This tool allows users to perform general feasibility checks for structural stiffness and load-bearing capacity. It also complements manual calculations typically done using engineering design books like Steel Structures: Design and Behavior by Charles G. Salmon and Mechanics of Materials by R.C. Hibbeler. While the calculator streamlines the process, traditional methods involve using standard equations and reference tables available in these textbooks.

FAQs
Are there standards for SHS and RHS dimensions used in structural design?
Yes, various standards exist, such as EN 10210 and EN 10219 in Europe, AS/NZS 1163 in Australia, and ASTM A500 in the United States, which specify dimensions and tolerances for these sections.
What are some common applications of SHS and RHS sections?
SHS and RHS sections are widely used in construction for columns, beams, trusses, and frames, as well as in mechanical applications like machine components and conveyor systems.
Can the moment of inertia for SHS/RHS sections vary with orientation?
Yes, the moment of inertia changes depending on the axis of rotation (major or minor axis), which affects the section's bending resistance in different directions.

How to verify a calculation
Engineering calculations require clarity, precision, and professionalism. Here are some best practices we use at CalcTree:
- Technical Requirements: Start with boundary conditions, units, sign conventions, and design standards.
- Check the Math: Review the calculation step-by-step. Clarify unusual steps, compare results with hand calculations or tools, and test with multiple examples.
- Peer Review: Have an independent reviewer check for logic, accuracy, and compliance.
