Abstract null null The present work investigates the elasto-visco-plastic buckling of thick plate structures. Methods to estimate the buckling of thin elasto-visco-plastic shells and plates are proposed in literature. To the knowledge of the authors, only few works present experimental results, and none treat the experimental elasto-visco-plastic buckling of thick plate. Thick rectangular plates are chosen as a structure of interest to study elasto-visco-plastic buckling. A modelling/experimenta...

Abstract null null In this paper, an extensive study on the web crippling behaviour of GFRP wide-flange (WF) section profiles with centred web perforation under interior-two-flange (ITF) loading is reported. Experimental investigation included material characterization tests and full scale web crippling experiments performed on 14 specimens with and without web perforations under ITF loading configuration. To examine the effect of web perforation, perforation sizes were varied between 0.2h and 0...

Abstract null null This paper proposes a framework of deep belief network (DBN) for studying the structural performance of cold-formed steel (CFS) channel sections with edge-stiffened/un-stiffened web holes, under axial compression. A total of 50,000 data points for training the DBN are generated from elasto plastic finite element analysis, which incorporates both initial geometric imperfections and residual stresses. A comparison against 23 experimental results was conducted, and it was found t...

Abstract null null Tube–gusset plate joints with multiple ring stiffeners are commonly used in steel tube towers. The load on the gusset plate can be distributed to each stiffener according to its Tension and Compression (T&C) stiffness. The ultimate state of joints with multi-stiffener plates can be equivalent to that of the stiffener plate. In this study, an experimental investigation and theoretical analysis of the failure mode and T&C stiffness of ring stiffener under symmetrical loading wer...

Abstract null null The present paper reports a thorough experimental and numerical investigation into the local–flexural interactive buckling behaviour and resistances of S690 high strength steel slender welded I-section columns. A testing programme, adopting two S690 high strength steel slender welded I-sections, was firstly conducted and included initial geometric imperfection measurements and ten pin-ended column tests. The testing programme was accompanied by a numerical modelling programme,...

Abstract null null Cold-formed steel bearing walls are frequently installed on concrete slabs, which do not provide perfectly rigid and uniform conditions. However, existing design guidance assumes bearing condition has no impact on axial capacity, though cold-formed steel compressive members are particularly susceptible to these end conditions. Additionally, studs are typically installed at the edge of the concrete slab, which is prone to spalling and geometric irregularities, and stud walls ar...

Abstract null null In this paper, an effective theoretical method is developed and experimentally validated for investigating the vibration behaviors of the simply supported sandwich plates with a pyramidal truss core on elastic foundation. An adjustable sliding support frame that can adapt to variations in the plate length and width is designed to realize the simply supported boundary conditions. The kinematic relations of the sandwich plates are derived, and the constitutive or stress–strain r...
