Kathage, Karsten; Lindner, Joachim; Misiek, Thomas; Schilling, Sivo | A proposal to adjust the design approach for the diaphragm action of shear panels according to Schardt and Strehl in line with European regulations | Steel Construction | 2/2013 | 107-116 | Articles |
AbstractIn Germany the stiffness and resistance of diaphragms used for stabilizing members are traditionally calculated according to the Schardt and Strehl approach. Compared with the approach of Bryan and Davies given in the ECCS Recommendations, it does not take into account the flexibility of the connections. This paper shows how to amend Schardt and Strehl’s approach to include this flexibility, leading to more realistic values of diaphragm stiffness. The article also introduces new procedures for the calculation of the resistance, adopted from European standards and recommendations. Finally, both a test and an example taken from the literature are recalculated for comparison. x | |||||

Camotim, Dinar; Basaglia, Cilmar | Buckling analysis of thin-walled steel structures using generalized beam theory (GBT): state-of-the-art report | Steel Construction | 2/2013 | 117-131 | Articles |
AbstractThis paper addresses the use of generalized beam theory (GBT) to analyse the local and global buckling behaviour of thin-walled steel members and structural systems. After a brief historical perspective of GBT developments, the main concepts and procedures involved in performing buckling analyses are summarized in a systematic fashion. That is followed by a state-of-the-art report concerning the most recent GBT formulations and applications that have been developed to assess the buckling behaviour of members, frames and trusses with various loading and support conditions. In order to illustrate the unique modal features and show the potential of the GBT approach to buckling analysis, numerical results and a few practical applications are presented and discussed; for validation purposes, most of these results are compared with values yielded by shell finite element analyses, performed in the ABAQUS and ANSYS programs. The paper closes with a few words on the future perspectives of GBT-based buckling analysis. x | |||||

Puthli, Ram; Packer, Jeffrey A. | Structural design using cold-formed hollow sections | Steel Construction | 2/2013 | 150-157 | Articles |
AbstractThis paper reviews the differences between the alternative types of structural hollow section products (cold-formed versus hot-finished) as they affect structural design in Europe, using the relevant product and design standards, with an emphasis on Rectangular Hollow Sections (RHS). Manufacturers of cold-formed structural hollow sections (CFSHS) are more numerous, so that their products are more widely available. Hot-finished structural hollow section (HFSHS) products are typically between 24 % and 54 % more expensive in Germany than their cold-formed counterparts, the lower differences being for large tonnages - a strong inducement in favour of CFSHS. The price difference may also vary within the European Union. The geometric and product properties which are distinctly unique to CFSHS are presented and shown to offer no restrictions in their use when in compliance with the appropriate clauses in the European standards. These are the influence of corner radii, welding in the corner area, material choice to avoid brittle fracture and suitability for welding CFSHS. A comparison of the structural performance of CFSHS and HFSHS shows equally efficient structural designs for both products. The points covered are the design of compression members - unfilled and concrete-filled, joint resistance - which typically governs selection of member sizes, as well as fatigue design, fire design and the resistance of braced steel frames to severe seismic loading. CFSHS are shown to be adequate under all these situations. x | |||||

Korbelá , Jaroslav; Kroupar, Miroslav; Ryjácek, Pavel; Schindler, Jiri | Steel superstructure saves concrete arch bridge over the River Ohre, Czech Republic | Steel Construction | 2/2013 | 158-162 | Reports |
AbstractThis paper describes the design and construction of the unique widening of a concrete arch bridge over the River Ohe using a lightweight steel superstructure. The bridge reconstruction formed part of the wider reconstruction measures for road I/6, including its upgrade from a two- to a four-lane highway, near Loket between Nové Sedlo and Sokolov in the north-west of the Czech Republic. Details of the erection of the steel structure and the strengthening of the concrete arch and piers are also given. x | |||||

AbstractThis bridge, which connects Slivenec with Lahovice, is the project that completes the highway bypass south of Prague, in the Lochkov Valley. The bridge structure is 425.3 m long, 35 m wide and reaches a maximum height of almost 65 m. From both the architectural and engineering points of view, the bridge is an unusual design, with a curved composite structure supported by inclined concrete piers in the central span. x | |||||

McFadden, Matthew R.; Packer, Jeffrey A. | Weld design and fabrication for RHS connections | Steel Construction | 1/2013 | 5-10 | Articles |
AbstractThe 2010 AISC Specification for Structural Steel Buildings has expanded its scope in chapter K “Design of HSS and Box Member Connections” to include a section K4 “Welds of Plates and Branches to Rectangular HSS”. This paper discusses the historical development of the effective weld properties and analyses the structural reliability of the provisions. Additionally, there is a discussion on recent changes in U.S. and Canadian specifications/ codes with regard to the limit states for fillet weld design and the acceptance/rejection of the (1.00 + 0.50 sin1.5) term. Finally, there is a discussion of the details of an experimental research programme being performed at the University of Toronto in collaboration with AISC to determine the weld effective length in RHS T-connections under branch in-plane bending moments. In conclusion, it is found that the inclusion of the (1.00 + 0.50 sin1.5) term for RHS gapped K-connections as well as T- and X-connections, based on the limit state of shear failure along the effective throat of the weld, may be unsafe for fillet weld design when used in conjunction with the current effective weld length rules. x | |||||
Latour, Massimo; Piluso, Vincenzo; Rizzano, Gianvittorio | Experimental behaviour of friction T-stub beam-to-column joints under cyclic loads | Steel Construction | 1/2013 | 11-18 | Articles |
AbstractEurocode 8 has introduced the possibility of adopting partial-strength joints for seismic-resistant MR frames, provided it is demonstrated that connections perform adequately under cyclic loads. A programme of experiments devoted to investigating the cyclic behaviour of traditional joint details has recently been carried out by the authors. Within this programme, the analysis of the results obtained has revealed that even though connections designed to dissipate the seismic energy in bolted components can provide significant advantages because they are easy to repair after a destructive seismic event, they possess reduced dissipation capacity when compared with RBS connections and traditional full-strength joints. An advanced approach aimed at enhancing the hysteretic behaviour of double split tee (DST) joints and the ambitious goal of preventing joint damage is presented here. The system proposed is based on the idea of using friction dampers within the components of beam-to-column joints. A preliminary set of prototypes has been tested experimentally and the performances of joints under cyclic loading conditions have been compared with those of traditional joint details. The experimental work was carried out at the Materials x | |||||

Henriques, José; da Silva, LuÃs Simões; Valente, Isabel | Design model for composite beam-to-reinforced concrete wall joints | Steel Construction | 1/2013 | 19-26 | Articles |
AbstractA design model for composite beam-to-reinforced concrete wall joints is presented and discussed in this paper. The model proposed is the component method extended to this type of joint. The characterization of the active components is therefore performed in terms of force-deformation curves. In this type of joint, special attention is paid to the steel-concrete connection where “new” components, not covered in EN 1993-1-8, are activated. The application of the model allows the designer to obtain the joint properties in terms of the moment-rotation curve. The accuracy of the proposed model is verified by comparing it with available experimental and numerical results. The latter were developed in the FE program ABAQUS and previously validated by experimental results. x | |||||
