About Yapıdan

Yapıdan is a free Turkish-language civil engineering reference and learning platform. It brings technical guides, worked problems and browser-based calculation tools together, helping readers move between an explanation and the corresponding calculation.

What you can explore

  • Structural behavior and materials: beam deflection and section-property calculators
  • Earthquake engineering: a design-spectrum learning tool
  • Geotechnics: soil and foundation calculations, plus SlopePro for slope-stability exploration
  • Frame analysis: CalcFrame for defining two-dimensional models and examining internal-force and displacement results

The platform organizes content around reinforced concrete, steel structures, geotechnical engineering, earthquake engineering and construction quantities. Individual tool pages describe methods, assumptions and limitations, with references identified where applicable.

For learning and preliminary review

These resources are intended for education and preliminary exploration. Results must be checked independently against the actual model and relevant requirements. They do not replace a qualified engineer’s project-specific analysis, design or approval.

Try the platform

Start from the homepage for guided topics, or open the calculation center to choose a tool. The main interface and guidance are in Turkish.
