A new dibenzocyclooctadiene lignan, longipedunin E (1), and a new natural product, benzoyl oxokadsuranol (2), together with seven known compounds 3–9, were isolated from the methanol extract of the stems of Kadsura longipedunculata. The structure e

Large-section and high-strength angle steel (LHS) columns have been increasingly used in steel structures in recent years, however existing corresponding design methods were mostly based on studies of mild carbon steels with normal-size sections. In

Based on the Generalised Beam Theory (GBT), two computing models are presented to analyse the distortional critical stress of cold-formed thin-walled inclined lipped channel beams bending about the minor axis. The computing model of rigid-body motion

The past study indicates that, when the space joint of concentric annular-stiffer is loaded, stress concentration may generate at corner. The destruction usually concentrates in the joint region, and then cannot generate “strong joint”. To change

The result of low cycle reversed loading indicates that,hysteresis loops of out stiffener ring joint performs good plumpness and stability, meanwhile, bulge is observed in the joint region. In order to explain this phenomenon, nonlinear simulation

In calculating the reliable capacity of carrying load of cold-formed thin-walled steel members, there has not yet been a proper method which directly takes into account the impact of the residual stress. Through the research of residual stress, model
