Method for determination of load-bearing capacity of haunched zones made of IPE-type rolled

Abstract

Recently the author have conducted an extensive theoretical analysis programme on lateral stability of steel portal frames of hot-rolled profiles. Specific software has been developed for automatic modelling and applying the GMNIA method with a view to propose simple and reliable design rules for practical use. A simplified method with equivalent compressed strut regarding haunched area was proven to be reliable. Therefore the author has analysed and simplified the method to make it easier to use.
