Buckling behaviour of thin-walled cold formed steel platforms subjected to bending
(2008)The paper studies the behaviour of thin walled cold formed steel beams in bending, through nonlinear finite element analysis. These types of beams are usually used as platforms in scaffold configurations. The research aims ... -
A mathematical method for the determination of the critical axial loads of continuous beams with unilateral constraints for various initial geometric imperfections
(2013)This paper deals with the calculation of the axial critical loads of continuous beams with unilateral constraints. The paper emphasizes in the determination of the instability loads of continuous beams with initial geometric ... -
A numerical model based on nonconvex-nonsmooth optimization for the simulation of bending tests on composite slabs with profiled steel sheeting
(2010)It is well known that the Calculation Of the ultimate strength of composite concrete slabs with profiled steel sheeting requires the determination of the longitudinal shear resistance which depends on the quality of the ... -
The unilateral contact buckling problem of continuous beams in the presence of initial geometric imperfections: An analytical approach based on the theory of elastic stability
(2011)An analytical method for the treatment of the elastic buckling problem of continuous beams with intermediate unilateral constraints is presented, which is based on the fundamental theory of elastic stability. The study ...
