Doctoral thesis
Open AccessCold-formed thin-walled steel sections are frequently used in pallet rack structures. This type of cross-sections are normally used as a columns and contains perforations uniformly distributed enabling the connection between ... -
Circular economy in practice: the fenix project
(2018)
Conference report
Restricted access - publisher's policyCircular economy is a concept even more exploited by governments and companies to share green principles. However, its real adoption at industrial level remains limited to either small-scaled pilot plants or appositely ... -
Comparison between numerical models for unbraced multiple bay pallet racks
(John Wiley & sons, 2023)
Conference report
Open AccessUnbraced conventional pallet racks are structures intended for the storage of goods (commonly palletized); they are composed of vertical uprights, horizontal beams, and braces, connected together to form a steel skeleton-like ... -
Concrete-filled cold-formed chord studs to improve the seismic performance of steel framing buildings
(University of Sydney, 2023)
Conference report
Restricted access - publisher's policyLight gauge steel framing is increasingly used, mainly for low-rise buildings. However, for mid-rise buildings, their lateral strength is rather low; therefore, seismic effects can be highly demanding. Steel bracing has ... -
Cost-effectively 3d-printed rigid and versatile interpenetrating polymer networks
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-08-02)
Article
Open AccessVersatile acrylate–epoxy hybrid formulations are becoming widespread in photo/thermal dual-processing scenarios, especially in 3D printing applications. Usually, parts are printed in a stereolithography or digital light ... -
Cross-aisle stiffness analysis of industrial welded cold-formed steel rack upright frames
(2019-08-01)
Article
Open AccessIn general, industrial cold-formed steel pallet racks consist of upright frames and pallet beams. In the United States, typically, the upright frames are made welding the braces to the uprights. If the brace to upright ... -
Cross-sectional optimization of perforated pallet rack columns against distortional and global buckling
(2023-11)
Article
Restricted access - confidentiality agreementThis paper presents a cross-sectional optimization procedure to increase the load carrying capacity of a perforated rack column under a compression load. The optimization method is based on a Genetic Algorithm (GA) combined ... -
Customary light-gauge steel framing construction with flat strap bracing. Seismicity limits for short to mid-rise buildings in Europe
(Springer, 2023-11-20)
Article
Open AccessOrdinary (customary) light gauge steel framing is a convenient construction technology; however, given the studs low axial capacity, it has been considered mainly for low-rise buildings in low seismicity regions. This paper ... -
Determination of beam-to-column connection characteristics in pallet rack structures: a comparison of the EN and ANSI methods and an analysis of the influence of the moment-to-shear ratios
(2013-05-14)
Article
Restricted access - publisher's policyhe beam-to-column connections in most of the pallet rack structures made of thin-walled steel sections are of the clip-on type. These connections are of a semi-rigid nature and have a non-linear moment–rotation relationship, ... -
