Avgerinou, Stella; Lignos, Xenophon; Tsarpalis, Dimitris; Vayas, Ioannis | Full-scale tests on used steel storage racks | Steel Construction | 3/2019 | 231-242 | Articles |
AbstractIndustrial storage operators use not only new pallet racking systems, but also old ones for which certification documents possibly do not exist. In order to check the carrying capacity of such racks, in addition to component tests, full-scale experimental tests were carried out on complete structures to help the development of reliable numerical models. The racks were subjected to vertical and pushover loads in the laboratory using an improved version of the base plates to achieve fixed support conditions. Vertical loading was imposed by filling tanks with water, an operation that was activated and controlled through an innovative hydraulic network specifically designed for this purpose. During the vertical loading tests, a moderate earthquake took place near the experimental facility and this influenced the rack behaviour positively. The spine brace was too flexible in the out-of-plane direction and did not participate in the resistance to lateral forces. Distortional buckling of the columns was observed at high lateral loads. The experimental tests allowed the calculation of conservative values for the behaviour factor q. x | |||||
Dulevski, Encho | Effective widths for class 1 and 2 composite girders at negative moments | Steel Construction | 3/2019 | 243-248 | Articles |
AbstractWhen ascertaining the effective widths of class 1 and 2 composite girders, it is claimed that at ULS, Eurocode 4 procedures give highly conservative results. A new approach to the problem is proposed in which the strain limitation values are introduced after deriving a new formula (graphically presented) with the intention of replacing the existing one. It turns out that the new effective width is significantly larger. Such a result leads to some advantages in reinforcement distribution in the support areas of continuous girders. It might also lead to some savings in reinforcing and structural steel. This is demonstrated by an example. Another example shows a situation in which the rough application of Eurocode 4 may produce a design with a lack of reliability for some of the bridge superstructure elements. The results obtained may also be useful for situations where a structure with composite girders already in service has to be redesigned for increased loads. 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 |
AbstractThe 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 |
AbstractRecently, 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 |
AbstractThis 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 |
AbstractThis 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 |
AbstractConnections 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 |
AbstractMany 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 | |||||

Zenner, Harald; Hinkelmann, Karsten | August Wöhler - founder of fatigue strength research - On the 200th anniversary of August Wöhler's birth | Steel Construction | 2/2019 | 156-162 | Articles |
AbstractThe year 2014 marked the 100th anniversary of August Wöhler's death. On that occasion the authors wrote a book about his scientific work, his work on the safety of components and structures in the emerging industrial society, his life and his significance for the historical development in the field of fatigue strength of components and structures [1]. Those investigations were accomplished in cooperation with the DVM (German Association for Materials Research and Testing). As national and international events have shown [2], that book is of great interest. Therefore, an English version suggested itself, not least because of the 200th anniversary of Wöhler's birth in 2019. x | |||||

Martin, Pierre-Olivier; Nguyen, Tien Minh; Davaine, Laurence | Effect of the torsional stiffness of closed-section stiffeners on plate buckling in Eurocode 3, Part 1-5 | Steel Construction | 1/2019 | 10-22 | Articles |
AbstractLongitudinally stiffened plates are commonly used to increase the resistance to plate buckling. Closed cross-section stiffeners provide high values of the torsional stiffness and thus are very efficient to avoid their premature lateral torsional buckling. With the current software tools, it is easy to assess the critical stress for the elastic global mode, taking into account the beneficial effect of these high values of torsional stiffness for stiffeners with closed cross-sections. However, the torsional stiffness of longitudinal stiffeners is not considered in the analytical formula proposed by Annex A of EN 1993-1-5 for the assessment of the global buckling critical stress. A study is presented here where the effect of the torsional stiffness of longitudinal stiffeners on the plate buckling criterion of EN 1993-1-5 has been analysed. 216 configurations of stiffened plates were calculated through finite element GMNIA non linear analyses. Their compressive strength thus obtained were compared to their resistance to plate buckling as predicted by EN 1993-1-5, either by considering their torsional stiffness with EBPlate software or by completely ignoring it. The study clearly shows that EN 1993-1-5 leads to unsafe results when the torsional stiffness is taken into account in the calculations. Finally, it is concluded that the torsional stiffness of longitudinal stiffeners has to be ignored in the design of stiffened plates according to EN 1993-1-5. x | |||||
Kuhnhenne, Markus; Pyschny, Dominik; Kramer, Lisa; Brieden, Matthias; Ummenhofer, Thomas; Ruff, Daniel C.; Fauth, Christian; Holz, Rainer | Mechanical and thermal performance of new liner tray solutions | Steel Construction | 1/2019 | 23-30 | Articles |
AbstractLiner tray wall systems are widely used for industrial and commercial buildings. Up until now, the main type used was the conventional solution with a thin (3 mm) separation strip between liner tray and outer shell. In the meantime, various solutions exist on the market to improve the thermal performance of this wall system. On the one hand, this paper deals with numerical studies that show how these new solutions reduce the heat transfer coefficient of liner tray wall systems. On the other hand, it is about the related increase in the fixing distance s1 and its influence on the mechanical performance of liner tray wall systems. Extensive experimental investigations have been performed on liner trays with a directly attached outer façade within the scope of the European RFCS Research Project GRISPE. Practicable calculation methods have been derived based on existing regulations and methods. This paper depicts by way of excerpts the results for liner trays with a directly attached outer façade for fastener distances that are not or insufficiently covered in the standards. x |
