RESUMO

Four continuum methods for torsional analysis of structural cores that consist of one or two channel sections, connected by lintel beams, are described. . First, Vlasov s theory for thin walled beams of open sections is used. In the second method,the shear defonnationis included.The third methoduses a closed box torsion-bending theory,andthe last one adaptsUmansky-Benscotertheoryto a perforatedcore. I The results obtained with these methods are analyzed and compared with a frame analogy model and also with experimental data
