🏗️ Modeling Steel Sheds in SAP2000

To ensure the strength, stability, and economic efficiency of any structure, it must be analyzed under various applied loads. These loads may include:

  • Dead load (self-weight)

  • Wind and snow loads

  • Seismic load

  • Live loads from equipment, occupants, cranes, etc.

Due to the variety and complexity of these forces, manual calculations are highly impractical. For this reason, engineers have long used structural analysis software. Among the most reliable and widely-used tools is SAP2000, which performs high-speed, accurate analysis and design based on international codes.

For shed-type structures, SAP2000 is particularly popular. The modeling process involves:

  1. Drawing shed elements based on geometry

  2. Defining materials and sections

  3. Assigning loads

  4. Running the analysis

The software helps the engineer optimize cross-sections by displaying:

  • Member stresses

  • Displacements

  • Load paths

📏 Design Codes Used

All structural loading must conform to relevant codes. In Iran, the following are used:

  • Part 6 of the Iranian National Building Code (2019 edition) – Load Determination

  • Standard No. 2800 (4th Edition) – Seismic Design Regulations

  • Part 10 of the Iranian Building Code (2013 edition) – Steel Structure Design

    • This edition switched from Allowable Stress Design (ASD) to Load and Resistance Factor Design (LRFD)

    • However, use of the 2008 (ASD) edition is still permitted based on the Ministry’s formal directive

Soole Pardaz supports both ASD and LRFD methods.

📝 Construction Drawings

After completing the SAP model and selecting member sections, the next step is to prepare construction drawings. These show:

  • Geometry, dimensions, and layout of structural members

  • Details of steel components and some non-structural elements

For steel sheds, these typically include:

  • Columns

  • Beams

  • Base plates

  • Bracing systems

  • Crane support details

  • Purlins

  • Connections

Because precision is critical for steel fabrication (especially plate cutting), it is recommended to use Tekla Structures to generate shop drawings. This ensures:

  • Accurate fabrication dimensions

  • Reduced risk of assembly errors

  • Automated material quantity extraction

  • Total and partial weights of all components

🔧 Shop Drawings vs. Construction Drawings

A common question is: Why are shop drawings necessary if construction drawings are provided?

Answer:

  • Construction drawings are prepared by the structural engineer and show general member dimensions only

  • They lack detailed cuts, angles, and exact positions needed in fabrication

  • Most are 2D (AutoCAD), while shop drawings are 3D models (Tekla), making errors easier to detect

  • Tekla provides error-checking tools not available in AutoCAD

  • Shop drawings are essential to avoid costly mistakes during production

Note: Shop drawing preparation is typically the responsibility of the fabricator.

📘 Structural Design Report (Calculations Booklet)

Because a shed includes numerous elements, not all can be designed in SAP2000. Many components require manual calculations, such as:

  • Connections

  • Base plates

  • Wind columns

  • Crane systems

Additionally, all load calculation steps and assumptions should be documented in the report.

🧱 Foundation Design

For foundation design, engineers can use SAFE software or perform manual calculations. In SAFE:

  1. Support reactions from SAP2000 are imported

  2. The foundation is modeled

  3. A trial-and-error approach is used for dimensioning

  4. Required reinforcement is calculated

  5. Final foundation drawings are produced

📊 Bill of Materials (BOM / Listofer)

A Bill of Materials (BoM) or "Listofer" includes:

  • Weights and volumes of all components

  • Quantities of steel, plates, and other materials

It is essential for:

  • Accurate material procurement

  • Cost estimation

The list can be generated manually or via Tekla Structures for higher precision.
