White, Donald W.; Slein, Ryan; To ay, O uzhan | Advancements in the stability design of steel frames considering general non-prismatic members - Extended Keynote of SDSS 2019 | Steel Construction | 1/2020 | 2-9 | Articles |
KurzfassungThis paper discusses an innovative approach to the design of planar steel frames composed of prismatic and/or non-prismatic members. The method evaluates the member stability limit states using an inelastic eigenvalue buckling analysis configured with column, beam and beam-column inelastic stiffness reduction factors derived from the ANSI/AISC 360-16 Specification. The resulting procedure provides a relatively rigorous evaluation of all member strength limits accounting for moment and axial force variations along the member lengths, non-prismatic geometry effects, general out-of-plane bracing conditions and beneficial end restraint from less-critical adjacent, unbraced segments and/or from end conditions. The approach uses a geometric non-linear pre-buckling analysis based on the AISC direct analysis method to estimate the in-plane internal forces. Given these forces, an eigenvalue buckling solution is conducted to evaluate the overall member stability. Other limit states are addressed through cross-section strength checks using the internal forces determined from the geometric non-linear load-displacement analysis. Calculations using this approach are compared with results from recent experimental tests. x | |||||
de Seixas Leal, Luiz Alberto Araújo; de Miranda Batista, Eduardo | Composite floor system with cold-formed trussed beams and prefabricated concrete slab - Selected and extended contribution of SDSS 2019 | Steel Construction | 1/2020 | 12-21 | Articles |
KurzfassungSteel-concrete composite floor systems represent a common solution for buildings, leading to reduced material consumption and improving the structural strength and flexural stiffness. Lightweight steel frame construction systems, based on the combination of thin-walled cold-formed steel members (CFS) and panels (e.g. wood, cementitious, gypsum plaster), may also benefit from the composite behaviour in the case of concrete slabs. In this context, full-scale experimental tests were conducted to evaluate the structural behaviour of a floor system conceived with 0.95 mm thick CFS trussed beams and prefabricated concrete slabs. An innovative solution for shear connectors was designed and tested in order to ensure full interaction between the CFS trussed beam and the concrete slab. The thin-walled channel (TWC) connector is based on a lipped channel CFS attached to the top chord of the truss by standard self-drilling screws. Experimental results indicate efficient behaviour of the TWC shear connectors with improved bending capacity of the floor system. x | |||||

Sato, Atsushi; Koyama, Yohei; Idota, Hideki; Sato, Yuki; Yagi, Shigeharu; Takaki, Sunao; Kamada, Manabu | Experimental study of steel beam-to-column connections with bolted joints where the dissipative zone is the panel zone - Selected and extended contribution of SDSS 2019 | Steel Construction | 1/2020 | 22-29 | Articles |
KurzfassungIt is well known that inelastic behaviour in the panel zone of beam-to-column connections can help to ensure a more stable structural performance, as the panel zone can absorb energy to prevent structural collapse. Although plastic deformation of up to only 30 % in the panel zone can contribute to improving performance according to Eurocode 8, in the Japanese code there is no limit when structural performance is verified. This paper describes full-scale testing of beam-to-column connections where the beam was connected to the column by a T-stub using high-strength bolts. In the test specimens, a shape similar to a T-stub was used for the continuity plate, and partial reinforcement at the panel was expected. The testing allowed the maximum strength and deformation capacity of the beam-to-column connection to be evaluated. x | |||||

Unterweger, Harald; Ecker, Alexander | Steel-lined pressure shafts - appropriate design for external pressure | Steel Construction | 1/2020 | 30-40 | Articles |
KurzfassungDuring inspection work, when the pipe is empty, a thin-walled steel pipe is susceptible to shell buckling due to external pressure. Comprehensive research activities, including tests, began in the 1960s, and analytical and empirical formulae were developed for design. x | |||||
Tousignant, Kyle; Packer, Jeffrey A. | Optimized design of fillet welds for CHS joints according to EN 1993-1-8 | Steel Construction | 1/2020 | 41-51 | Articles |
KurzfassungDesigning fillet welds using the directional method of EN 1993-1-8 requires the consideration of force components, converted to stresses, located in the plane of the weld throat. For circular hollow section (CHS) joints, considering these “stress components” can be exceedingly difficult. An approach to applying the directional method to CHS joints is developed in this paper. The directional and simplified methods of EN 1993-1-8 are then evaluated against available finite-element data, validated from recent tests on weld-critical CHS X-joints according to the standard evaluation procedure of EN 1990. Despite inherent non-uniform loading of the weld around the perimeter of the brace, it is shown that taking the total weld length to be effective is safe for both methods. Procedures are given so that these methods can be used to design fillet welds in CHS joints as “fit-for-purpose”, as permitted by EN 1993-1-8 and ISO 14346, and new design charts are produced for minimum fillet welds that develop the axial capacity of the connected brace. x | |||||
Bardopoulos, Foivos; Papagiannopoulos, George; Pnevmatikos, Nikos | Design considerations for photovoltaic panel arrays made from aluminium: a case study - Design of photovoltaic panels with aluminium members | Steel Construction | 1/2020 | 52-60 | Articles |
KurzfassungThis paper presents the design considerations for typical photovoltaic panel arrays having aluminium members. Section and member design checks are performed according to Eurocode 9 on the basis of the wind, snow and seismic loads of Eurocodes 1 and 8. Improvements to the design are then sought, starting by reducing the distance between the vertical posts and then by changing the thickness of specific sections. Following that, the effects of member imperfections and connection flexibility are studied using a reduced flexural rigidity and different rotational stiffness values respectively. The degree of dynamic coupling when the array is placed on the top floor of an existing building as well as the influence of founding the vertical posts on compliant ground are also evaluated. x | |||||

Ernst & Sohn (Hrsg.) | Sonderheft: Brandschutz 2019 | Bautechnik | 12/2019 | 1-68 | Sonderheft |
KurzfassungBrandschutz scheint durch permanent neue Regelwerke, Richtlinien, Normen und gesetzliche Vorschriften immer komplexer zu werden. Darüber hinaus erfordern neue Baustoffe und moderne Bauweisen von den Akteuren ständig neues Fachwissen. So soll beispielsweise ab 2019 die Produktnorm EN 16034 in Kombination mit Innentüren anwendbar sein. Dann können Ausschreibungen und Angebote in den anwendbaren Bereichen der EN 16034 und nach Ergänzung der fehlenden Normen in den gängigsten Produktbereichen für Innen-/Außentüren und Tore erfolgen. Mit dem zunehmenden Holzbau insbesondere im mehrgeschossigen Wohnungsbau und bei Aufstockungen wird ein weiterer Brandschutzschwerpunkt immer wichtiger. x | |||||
Fröch, Georg; Flora, Matthias; Gächter, Werner; Harpf, Florian; Tautschnig, Arnold | Anwendungsmöglichkeiten eines digitalen Baugrundmodells im Tunnelbau | Bautechnik | 12/2019 | 885-895 | Aufsätze |
KurzfassungDigitale Bauwerksmodelle zur Unterstützung der relevanten Prozesse in der Wertschöpfungskette Bau erobern zunehmend den Infrastrukturbau. Während im Hochbau 3-D-Planung und BIM gebräuchlich sind, werden die Planungsunterlagen von Infrastrukturbauwerken derzeit noch mehrheitlich in 2-D ausgearbeitet. Falls die Planung dreidimensional erfolgt, werden in den wenigsten Fällen den Volumenkörpern Eigenschaften zugeordnet. Diese Zuordnung wäre jedoch eine Grundvoraussetzung für die “BIM-Arbeitsweise”. x |
