Non-linear stability analysis of imperfect thin-walled composite beams
(Pergamon-Elsevier Science Ltd, 2010-03)
The static non-linear behavior of thin-walled composite beams is analyzed considering the effect of initial imperfections. A simple approach is used for determining the influence of imperfection on the buckling, prebuckling ...
Induced moments and lateral deflections in columns with initial imperfections and semirigid connections:
(Universidad Nacional de Colombia Sede Medellín, 2012)
Closed-form expressions that can be used to evaluate the induced elastic bending moments and second-order deflections in slender prismatic columns with initial geometric imperfections (i.e., initial curvature and ...
Análise global de edifícios de concreto: efeitos de segunda ordem devidos à torção e efeitos de desaprumo
(Universidade Federal do Rio Grande do NorteBrasilUFRNEngenharia Civil, 2018)
The structural analysis is one of the fundamental steps in structural design development. The structure’s global analysis allow the determination of forces, stresses, displacements and strains, which are information necessary ...
Quasi-bifurcation and Imperfection-sensitivity of Cylindrical Shells under Pressures due to an Explosion
(Shahid Chamran University of Ahvaz, 2021-03)
The static and dynamic behavior of a horizontal cylindrical shell (as used to store fuels in tanks) is investigated in this work by means of computational modeling. Under a distributed pressure commonly used to model effects ...
Induced moments and lateral deflections in columns with initial imperfections and semirigid connections: ii) verification and examples
(Universidad Nacional de Colombia Sede Medellín, 2012)
An analytical method and the closed-form expressions derived in a companion paper are used to evaluate the induced elastic bending moments and second-order deflections in slender prismatic columns with initial geometric ...
On micro-buckling of unidirectional fiber-reinforced composites by means of computational micromechanics
(Latin Amer J Solids Structures, 2016-12)
Micro-buckling of unidirectional fiber-reinforced composites is investigated in this paper by means of an explicit representation of a geometrically imperfect fiber within the context of kinematical and material non-linear ...
