Evaluation of Ayrton–Perry formula to predict the compressive strength of batten columns

摘要: Abstract This research was performed to evaluate two analytical methods for predicting the compressive strength of batten columns. Batten columns were subjected pure axial compression, and measured. The used included well-known Ayrton–Perry ultimate curve calculate imperfect solid web columns, but their validity has not yet been studied experimentally on built-up geometrical parameters considered plate spacing dimensions distance between longitudinal chords. results show that generally valid prediction in Using average leads best column strength. It also shown initial imperfections could have a more important effect than specifications value
