- Size the column using initial design
- Calculate axial load and bending moment using appropriate analysis method (NEd, Mtop and Mbottom).
- Find the effective length (lo).
- Find the first order moments (Mo1 and Mo2)
- Find the slenderness ( λ = lo/i, λ = 3.46*lo/h for rectangular column and λ = 4*lo/d for circular column, h and d are the overall depth and column diameter respectively )
- Find the slenderness limit λlim
- If λ ≥ λlim column is not slender.
- Then MEd = Mo2
- Find As for NEd and MEd
Design of reinforced concrete structures, steel structures, foundations, geotechnical designs, construction materials, structural failures, etc. is discussed.
