Frequently Asked Questions

What is a PEB (Pre-Engineered Building)?

A pre-engineered steel building whose columns and rafters are designed as tapered sections matched to the actual forces, which saves steel. It is popular for factories, warehouses, and wide-span buildings.

Is this PEB calculator free?

You can analyze the structure and view the 3D model for free right away, no signup required. Saving projects and exporting PDF reports is available with a 7-day free trial signup.

Does it account for wind load?

Yes. It analyzes wind load per the DPT 1311 (มยผ.1311) standard, including the uplift case that reverses the moment and turns the bottom flange of the rafter into a compression flange requiring a lateral-torsional buckling (LTB) check.

What does the program design for me?

It analyzes the frame forces, designs the tapered columns and rafters, checks LTB and compression, designs the Z-purlins, and shows a 3D model of the whole building.

Can the results be used for construction directly?

This is a preliminary design tool. The results must be reviewed and certified by a licensed engineer before being used for actual construction.
