Analysis of pallet rack beam members through a nonlinear GBT formulation with sectional constraints

Thin-walled open cross-sections are commonly used in steel storage pallet rack structures. In some cases, sections employed as beam members. These members usually have weld spots along their length order to reduce the distortional deformation under a flexural load. On other hand, typically connected columns by means of claws, which exhibit nonlinear moment - rotation relationship. two characteristic should be taken into account properly reproduce structural response. this paper, Generalised Beam Theory (GBT) is perform geometrical analysis taking and beam-to-column connection behavior account. The influence number location spots, well behavior, member evaluated GBT analyses. results show that use small could enough minimize deformation. Moreover, stiffness also has on Finally, successfully compared with shell finite element
