About AK Structure
AK Structure is a free collection of civil and structural engineering calculators. Every tool follows a published code – ACI 318-19, ASCE 7, BS and others – and shows the full working with the clause behind each step, so results can be checked instead of trusted blindly.
Who builds the tools
Eng. Anwar Ali Khan – MSc Civil Engineering (Structural), Professional Engineer (PEC), registered member of the Saudi Council of Engineers, and member of ASCE/SEI.
I am a civil and structural engineer with more than ten years of experience in design, site and technical-office work. I currently work as a Technical Manager on design-and-build marine and bridge infrastructure on Saudi Arabia's Red Sea coast, leading shop drawings, bar bending schedules, submittals and design coordination. Before that I designed multi-storey residential, commercial and hospital buildings in Khyber Pakhtunkhwa, Pakistan, to ACI, ASCE and the Building Code of Pakistan, and worked as a site engineer.
I built this website because engineers need quick calculations they can trust and check. The tools are free. They support – but never replace – the judgement of a qualified engineer.
How the tools are checked
- Formulas and tables are taken from the code edition named on each page.
- Every tool is cross-checked against an independent Excel calculation, and against hand calculations and published examples.
- Each page shows its version and the date it was last reviewed.
