  11. Design procedure for a short column

  12. Design procedure for a short column Use of interaction diagrams:

  13. 500KN.m 250KN.m Design procedure for a short column Example 1 Design reinforcement for a 400 mm x 500 mm tied column. The column, which is part of a braced frame, has an unsupported length of 3.0 m. It is subjected to a factored axial load of 2400 kN in addition to a factored bending moment as shown.

  14. Note to use the last Instruction diagrams (English units) divide and By 7.0
