Abstract In those cases where architectural requirements are a priority, hollow sections the preferred solution. Considering cross‐sectional classes 1 and 2, plastic design is possibility that preferable for both economic ecological reasons. technical standards literature, wide variety of interaction formulae can be found. However, in most cases, information about their accuracy not provided. t...

This paper reviews contemporary rules in CSA S16:19, AISC 360-16 and EN 1994-1-1 for concrete-filled hollow structural sections (HSS), covering materials, cross-section classification, concentrically loaded columns. Results from 453 tests on axially compressed HSS members are compared to predicted strengths using current (CSA 1994-1-1) recommended S16 design equations (with limits of validity),...

Abstract Wire Arc Additive Manufacturing (WAAM) has the potential to produce free form metallic structures, suitable for use in construction industry, and so is currently being rapidly developed by structural engineers. This paper details an experimental program investigating stability performance of ten WAAM 316L stainless steel square hollow section stub columns with varying cross‐sectional s...

The development of co-electrospun (co-ES) hollow microfibrous assemblies of an appreciable thickness is critical for many practical applications, including filtration membranes and tissue-mimicking scaffolds. In this study, thick uniaxially aligned hollow microfibrous assemblies forming fiber bundles and strips were prepared by co-ES of polycaprolactone (PCL) and polyethylene oxide (PEO) as she...

This paper is concerned with investigating of the plastic behaviour on gap K-joints truss girders, made from thin-walled rectangular hollow section members. An experimental study was carried out a full-scale girder under concentrated load two central nodes. A numerical analysis using ABAQUS in order to clearly see this type joint and make comparison experimentation. will it possible examine att...

We explore an acoustic scattering cancellation shell for buoyant hollow cylinders submersed in a water background. A thin, low-shear, elastic coating is used to cancel the monopole scattering from an air-filled, neutrally buoyant steel shell for all frequencies where the wavelength is larger than the object diameter. By design, the uncoated shell also has an effective density close to the aqueo...

A Fluidized Bed Metal–Organic Chemical Vapor Deposition (FB-MOCVD) process was developed for the growth of tin oxide thin films on large hollow Ni particles. Tetraethyl tin was used as tin source and dry air both as fluidization gas and oxidant reagent. The SnO2 films were grown in a FBCVD reactor under reduced pressure (13.3 kPa) in the temperature range of 633–663 K. A series of specific expe...

Enhancing the ease of construction fillers and large-span floors their overall mechanical performance is critical for prefabricated hollow slabs in modular building structures. Therefore, we propose a novel assembly integral two-way floor structure (8.4 × 8.4 m) consisting permanent (BDF ribbed steel mesh box) three precast one-way hollow-core with I-shaped flexural sections to address above pr...
