Delémont, Thierry; Bouvet, Caroline; Herion, Stefan; Hrabowski, Jennifer; Pittet, Yves | Pont du Lanciau - eine Rohrfachwerkbrücke als Ersatzneubau | Stahlbau | 2/2019 | 146-152 | Aufsätze |
KurzfassungDie im Jahr 1904 errichtete Eisenbahnbrücke von Lanciau musste durch eine neue Brücke ersetzt werden, die eine durchgehende Schotterbahn ermöglicht. Die neue Brücke wurde mit der Idee entworfen, den Geist der alten Pont du Lanciau beizubehalten und diese als Fachwerkkonstruktion auszuführen. Allerdings wurde sie sowohl hinsichtlich ihrer Form (räumlicher Dreiecksbinder mit variabler Höhe) als auch ihrer Profilquerschnitte (Rohre) modernisiert. Eine auf dem Tragwerk aufgesetzte und mit den Obergurten verbundene Betonwanne wird genutzt, um die Steifigkeit der Brücke zu erhöhen. Pont du Lanciau ist damit eine der ersten Eisenbahnbrücken mit einem tragenden Fachwerk aus Hohlprofilen, das dank der kompakten, direkt verschweißten Rohre ein ästhetisches Erscheinungsbild liefert, das sich perfekt in die Umgebung integriert. Im Folgenden wird auf die verschiedenen Aspekte bei der Realisierung dieses Vorhabens eingegangen. x | |||||
Haspel, Lorenz | Netzwerkbogenbrücken mit Hängern aus Carbon | Stahlbau | 2/2019 | 153-159 | Aufsätze |
KurzfassungDie Verwendung von eingeschweißten Stahlprofilen als Netzwerkhänger in Kombination mit den auf Schwingbreiten und Vermeidung von Hängerausfall optimierten Netzwerklayouts führt zu technischen Herausforderungen, welche in der jüngeren Vergangenheit nicht immer befriedigend gelöst werden konnten [1]. Insbesondere bei langen, flach geneigten Hängern treten Schwierigkeiten im Zusammenhang mit der Durchbiegung infolge Eigengewicht und Veränderung der Durchbiegung infolge Normalkraftamplituden sowie Zusatzbeanspruchungen aus winderregten Schwingungen auf [1, 2]. x | |||||
Teutsch, Uwe; Steiner, Fredy | Raumhaltiger Kranträger - Sozialräume als gestapelte Raumsequenz in einer Werkhalle | Stahlbau | 2/2019 | 160-166 | Berichte |
KurzfassungMit dem Umbau einer Werkhalle soll ein Schulungs-, ein Aufenthalts- und ein Garderobenraum für die Mitarbeiter einer Firma im Fahrleitungssektor geschaffen werden. Da eine Erweiterung der Halle auf dem freien Gelände des Firmenareals den Werkverkehr zu stark beeinträchtigen würde, kam nur eine Ergänzung im Inneren der Halle infrage. Um die Verkehrsflächen in der Halle nicht zu stark zu reduzieren, wurden die Räume aufeinandergestapelt und zwischen die bestehenden Kranbahnen der südwestlichen Ecke der dreischiffigen Stahlhalle gehängt. Durch das Eliminieren des Krangewichts in diesem Bereich konnte das frei werdende statische Potenzial (die Laufkatzen der beiden Krane trugen bis zu 20 t schwere Lasten) des bestehenden Stahltragwerks der Halle genutzt werden. Die beiden aufgehängten Obergeschosse der Sozialräume sind als leichte, hybride Konstruktion aus Stahl und Hohlkastenelementen aus Holz (18 t Stahl und 25 t Ausbaulasten) ausgebildet und anstelle des Krans in die Kranbahnen eingehängt. Die Position der Aufhängung ist so gewählt, dass alle Mehrlasten über die bestehende Tragkonstruktion der Halle abgeleitet werden können, ohne das Tragwerk und die Fundation verstärken zu müssen. Lediglich die fassadenseitige Kranbahn ist partiell mit dünnen aufgeschweißten Blechen an den Flanschen verstärkt worden, sowie die vier nächstgelegenen Kranbahnkonsolen. x | |||||

Schäfer, Markus | European design code for composite structures in steel and concrete - Historical development and investigation in the second generation of Eurocode 4 | Steel Construction | 2/2019 | 70-81 | Articles |
KurzfassungThe Eurocodes (EC) represent European norms (EN) for the design and construction of building and bridge structures. The development of these European design codes is carried out on behalf of the European Union (EU) by the “European Committee for Standardization - CEN”. The Eurocodes have been in use for some years now. The motivation behind the development of the Eurocodes is the harmonization of the planning and design process for the structural components and construction elements of buildings and bridges all over Europe. Based on the experience gained through the use of the Eurocode conditions in recent years and many comments from industry, a revision of all parts of the Eurocode is currently in progress. The aim is to adapt the current design standards to the state of the art and research, to simplify the application and to harmonize the Eurocodes with each other. Finally, these modifications will be transferred to the second generation of European standards. An overview of the development phases and project teams is presented in this paper, accompanied by an insight into current standardization work and the technical discussions, mainly focusing on EN 1994-1-1. x | |||||

Nie, Jing; Sugimoto, Hikaru; Ono, Kiyoshi; Miyashita, Takeshi; Matsumura, Masahide; Okada, Seiji | An experimental study on the local buckling strength of an SBHS700 stub column with cruciform section - With an overview of the mechanical properties of SBHS700 | Steel Construction | 2/2019 | 82-90 | Articles |
KurzfassungRecently, SBHS (Steels for Bridge High-Performance Structure) has been introduced in Japan because of its remarkable mechanical properties. The main features of SBHS are high yield strength, improved toughness and weldability, which are superior to conventional steel materials at the corresponding tensile strength grades. In this study, these material properties of SBHS were compared with conventional steel materials through experimental studies as well as the Japanese design specifications. The main focus of this paper is the evaluation of the local buckling strength of two SBHS700 stub columns, each with cruciform section through compression tests. The load-displacement relationship, strain bifurcation related to plate buckling and out-of-plane deformation are discussed. Two test specimens with different width-to-thickness ratio parameters RR are compared. As the results indicate, for the specimen having a larger RR, an abrupt decrease in load was observed after the peak load, whereas the decrease in load for the specimen with a smaller RR proceeded gradually after the peak load with a much larger vertical displacement. In terms of local buckling strength, it was found to be possible to evaluate the SBHS700 stub column with cruciform section based on the existing ultimate strength curves. x | |||||

Hradil, Petr; Fülöp, Ludovic; Ungureanu, Viorel | Reusability of components from single-storey steel-framed buildings | Steel Construction | 2/2019 | 91-97 | Articles |
KurzfassungThis paper presents the development of the method for predicting the reusability of building components and whole structures and a pilot study of three different single-storey steel buildings in Finland. The method enables various building parts and products to be classified through a procedure to calculate their reusability index. These values can be further used to produce a single reusability indicator for the whole end-of-life scenario (e.g. complete or partial building reuse). The aggregated result of the whole building may be very useful when planning demolition or reconstruction works as well as when assessing the environmental impact of the new buildings. The main new thing explored in this paper is the possibility of integrating the economyaspect of the recovered components in the reusability assessment. Indeed, the reusability index developed earlier was purely based on the technical requirements of recovering, remanufacturing and reusing components. Hence, it was a technical reusability indicator. The possibility ofincluding information on the prospective marketability of the recovered component is a valuable extension to this method. x | |||||

Maali, Mahyar; K?l?ç, Mahmut; Ayd?n, Abdulkadir Cüneyt | Experimental behaviour of bolted connections with stiffeners | Steel Construction | 2/2019 | 105-113 | Articles |
KurzfassungThis paper focuses on the behaviour of connections with stiffened top and seat angles. There is a discussion of nine statically loaded full-scale tests carried out in three groups for different thicknesses of top and seat angle stiffeners. The purpose was to provide the necessary data to develop Eurocode 3. The maximum bending moment increased with the increase in stiffener thickness from 6 to 10 mm. Moreover, the plastic flexural resistance and bending moment capacity increased as the length of top and seat angles decreased. Furthermore, the plastic region of the seat angle section parallel to beam was greater than the vertical section of the angle, and the dissipated energy depended on the lengths of the angles. x | |||||

Lange, Jörg; Kawohl, Anne | Tension-shear interaction of high-strength bolts during and after fire | Steel Construction | 2/2019 | 124-134 | Articles |
KurzfassungConnections in steel structures play an essential role in the structural stability of the entire construction. This is also true in the event of a fire. The difficulty in designing connections for fire lies in the fact that not only material properties, but also loads applied to the connections change depending on temperature. In addition, the temperature-dependent decrease in the tensile strength of high-strength bolts does not coincide with the decrease in shear strength. So far, the influence of combined tension and shear loading on high-strength bolts has not been studied in detail. x | |||||

Far, Harry | Dynamic behaviour of unbraced steel frames resting on soft ground | Steel Construction | 2/2019 | 135-140 | Articles |
KurzfassungMany recent earthquakes clearly illustrate the importance of local ground properties for the dynamic response of structures. The dynamic response of an engineering structure is influenced by the medium on which it is founded. On solid rock, a fixed-base structural response occurs which can be evaluated by subjecting the foundation to the free-field ground motion occurring in the absence of the structure. However, on deformable ground, a feedback loop exists. In other words, when a feedback loop exists, the structure responds to the dynamics of the soil, while the soil also responds to the dynamics of the structure. Structural response is then governed by the interplay between the characteristics of the ground, the structure and the input motion. This study involved a numerical investigation of the dynamic behaviour of unbraced steel frames resting on soft ground. Two types of mid-rise unbraced steel frame, including 5- and 15-storey buildings on a soft soil deposit, were selected and analysed under the influence of three different earthquake acceleration records. The above-mentioned frames were analysed under two different boundary conditions: i) fixed-base (no soil-structure interaction) and ii) flexible-base (considering soil-structure interaction). The results of the analyses in terms of structural forces and lateral displacements for the above-mentioned boundary conditions are compared and discussed. x | |||||
