Experimental evaluation of elastic critical load in batten columns

摘要: Abstract A test program was devised for batten columns subjected to pure axial compression determine the elastic critical load. Tests were conducted using specimens with various plate dimensions and also, distance between two longitudinal chords. For obtaining load from results, modified Southwell plot used. The resulted loads compared those obtained three existing theoretical methods of equivalent slenderness, Paul approach finally SSRC method. It is found that are generally conservative. most accurate method slenderness Engesser equation gives results least accuracy. accuracy slightly less than
