Syllabus

  • 1.–3. Calculation analysis of the cross section bearing capacity loaded by combination of bending moment and normal force - physical non-linearity of the concrete and steel. Cross section layer model for compression part. Algorithm development of the calculation with help of Microsoft Excel program.
