Manco, Tiago; Rigueiro, Maria Constança; Martins, João Pedro; da Silva, LuÃs Simões | Comparative assessment of the design of tubular elements according to offshore design standards and Eurocode 3 | Steel Construction | 4/2016 | 266-278 | Articles |
AbstractSteel circular tubular elements are among the most commonly used types of structural element in offshore structures. The objective of this paper is to perform a comparative analysis of design standards for offshore structures with a focus on the structural design of these elements. The intention is to reach a conclusion about the level of safety that offshore and construction standards provide regarding the design of tubular circular elements. To this end, the bearing capacity obtained with ISO 19902 and Eurocode 3 (which does not contain specific provisions for offshore structures) parts 1-1 and 1-6 will be compared in a broad parametric study. Subsequently, the accuracy and level of safety that ISO and EC3 assume are assessed through numerical analysis using the ABAQUS software. The performance of a set of steel circular tubular elements is evaluated under axial compression and hydrostatic pressure. Finally, the interaction between axial compression and hydrostatic pressure is also analysed. x | |||||

Arrayago, Itsaso; Real, Esther; Mirambell, Enrique | Tests on ferritic stainless steel simply supported and continuous SHS and RHS beams | Steel Construction | 4/2016 | 291-295 | Articles |
AbstractDevelopment of efficient design guidance for stainless steel structures (considering non-linear behaviour, strain hardening and allowing for moment redistribution in indeterminate structures) is crucial for the widespread use of this corrosion-resistant material. This paper presents an experimental programme involving ferritic stainless steel simply supported and continuous beams (RHS and SHS) and the assessment of existing cross-sectional classifications and different plastic design methods available in the literature for indeterminate stainless steel structures, not currently allowed in stainless steel standards. The analysis indicated that some cross-sectional classification limits seem to be too optimistic for ferritic stainless steels and further research is needed in order to extend plastic design to these grades. x | |||||
Barros dos Santos, Gabriel; de Miranda Batista, Eduardo; de Araújo, Afonso Henrique Mascarenhas | Behaviour of RHS beam-to-column bolted steel connections | Steel Construction | 4/2016 | 296-304 | Articles |
AbstractThe connection concept is a key point in the design of steel structures which affects fabrication, erection procedures and the final costs. Welding processes have been extensively used for tubular trussed girders by combining shop welding with bolted flange solutions to facilitate straightforward connection procedures during erection. The present research addresses the behaviour of innovative beam-to-column bolted connections for steel rectangular hollow sections (RHS) which combine simplicity in fabrication and erection, favourable aesthetics for the case of visible structures and structural effectiveness. Four cruciform prototypes were tested under a static non-reversible bending moment with different bolted conditions: i) non-friction and ii) friction connection. The experimental results show that the proposed geometry with friction connections is able to develop a rigid elastic moment-rotation response up to usual loading conditions. x | |||||

AbstractThe research into a specific type of unstiffened extended end-plate joint used to connect I-shaped beams to concrete-filled rectangular hollow section columns is presented in this paper.

Neves, Luis F. | Experimental and numerical assessment of RHS T-joints subjected to brace and chord axial forces | Steel Construction | 4/2016 | 315-322 | Articles |
AbstractThe demand for the use of hollow section structures in construction has experienced great progress in Brazil, despite being widely used for a long time in Europe and developed countries. The release of a Brazilian Technical Standard specifically for the design of hollow sections confirms this trend, together with the need for increased dissemination and implementation of studies and research to enable a better understanding and development of this technology. This paper presents experimental and numerical evaluations of the influence of chord normal stresses on the behaviour of tubular T-joints. The experimental programme consisted of six tests applying compressive loads to the brace. These results were compared with the numerical results obtained from a finite element model simulation performed in ANSYS to extend the results to cases with tension forces on the brace. The results were compared with the design provisions in Eurocode 3, Brazilian standard NBR 16239:2013 and ISO 14346. A new equation for the case where compression loads are applied to the chord for n ≤ -0.5 is therefore proposed, providing better agreement with the experimental and numerical results x | |||||
Romero, Manuel L.; Albero, Vicente; Espinós, Ana; Hospitaler, Antonio; Pons, David; Portolés, José M.; Ibañez, Carmen | Circular concrete-filled dual steel columns with ultrahigh-strength concrete | Steel Construction | 4/2016 | 323-330 | Articles |
AbstractThis paper presents the results of an experimental campaign in which the buckling resistance of 12 concrete-filled dual steel columns was ascertained. Whereas some papers in the literature describe investigations into concentrically loaded stub columns with such typology, no investigations of slender columns have been found to date. The tests presented in this paper are the preliminary results of an extensive experimental campaign (28 tests) that analysed the effects of two parameters: strength of concrete (normal- and ultrahigh-strength concrete) and the ratio between the thicknesses of the inner and outer steel tubes. A numerical model was also developed and validated, which helps further investigations. The buckling load of the specimens at room temperature is analysed in terms of the strength of the concrete and the appropriate distribution of the steel in the composite column. By maintaining the same total area of steel, two combinations were initially studied: “thick outer tube-thin inner tube” and “thin outer tube-thick inner tube”. Finally, a discussion about the Eurocode 4 simplified method for composite columns, applied to these innovative specimens, is presented and shows unreliable results. Therefore, further tests would be needed to assess accurately the Eurocode 4 simplified method. x | |||||
Khador, Majd; Chan, Tak-Ming | Cyclic behaviour of external diaphragm joint to CHS column with built-in replaceable links | Steel Construction | 4/2016 | 331-338 | Articles |
AbstractA series of full-scale laboratory experiments was conducted to investigate the cyclic behaviour of an external diaphragm joint between a steel I-beam and a circular hollow section column. The joint incorporated two diaphragm plates (DPs) welded to the column's external wall and bolted to the flanges of the beam using tapered cover plates (TCPs). The joint was designed to limit yielding and plastic hinging of the TCPs while the other joint components remained elastic. This is necessary if the joint is to qualify for use in structures classified in the damage control structural performance range according to FEMA 356. Two parameters of the TCPs are investigated in this paper: steel grade and bolt preload force. The use of higher steel grades was found to impose undesirable higher strain demands on the beam and DPs and dissipate less energy than the joints with the lower grade. A controlled reduction in the bolt preload force allowed connection slippage to occur beyond the serviceability limit, created an additional energy dissipation fuse and allowed rotation of the plastic hinge region to exceed the 25 mrad required for medium ductility class structures. x | |||||

Wardenier, Jaap; Packer, Jeffrey; Puthli, Ram; Bijlaard, Frans | Re-evaluation of the shear criterion for RHS overlap joints | Steel Construction | 4/2016 | 339-348 | Articles |
AbstractThis paper deals with a proposal to revise the effective width terms in the brace shear criterion for overlap joints in rectangular hollow sections (RHS). The background to the design equations in ISO 14346 for the failure modes, brace effective width, chord M-N interaction and brace shear are described first. That is followed by the relation between overlap joints in circular hollow sections and those in rectangular hollow sections and those with an I- or H-section chord. Finally, it is shown that the effective width terms in the brace shear criterion can - in the case of 100 % overlap joints - be better related to the thickness of the overlapped brace. In the case of smaller overlaps, &lgr;ov, limit ≤ &lgr;ov ≤ 100 %, the effective width should also be related to the thickness of the overlapping brace, where &lgr;ov, limit depends on whether the hidden seam at the toe of the overlapped brace has been welded. x | |||||
Lindner, Joachim; Kuhlmann, Ulrike; Just, Adrian | Verification of flexural buckling according to Eurocode 3 part 1-1 using bow imperfections | Steel Construction | 4/2016 | 349-362 | Articles |
AbstractThe resistance of compression members may be calculated by the design buckling resistance based on the reduction factor &ggr;, which depends on the slenderness, or by the cross-section resistance based on internal forces according to a second-order analysis taking into account equivalent initial bow imperfections as well. The second way is especially advantageous in the case of axial forces and bending. Values for equivalent initial bow imperfections are given in codes such as Eurocode 3 [5] or DIN 18800 [4]. For comparison, initial bow imperfections are derived here from the buckling curves for compression members with different cross-sections, buckling directions and steel grades based on different types of cross-sectional interaction. The results are discussed and commented with regard to the design of compression members. Furthermore, investigations are carried out for cases of axial compression and bending moments My or Mz. Data available from ultimate load calculations are used for comparison. The consequences for the assumed design verification according to second-order theory are discussed and a proposal is presented. x | |||||
Helbig, Thorsten; Kamp, Florian; Schieber, Roman; Oppe, Matthias; Torsing, Rob; Kieft, Ralph | Curved directly glazed steel structure - New departure station, E-Line, The Hague | Steel Construction | 4/2016 | 363-368 | Reports |
AbstractZJA Zwarts & Jansma Architects have designed a new light rail departure station in The Hague, The Netherlands. The spatial roof structure of the station is made of rolled steel rectangular hollow sections arranged in two independent layers rigidly connected to each other. A glass envelope covering the roof structure matches the contours of the steel exactly. Since the diamond-shaped glass panes could only be attached to the outer layer of the steel grid, the panes (with edge lengths of approx. 1.30 m) are supported on two sides only. When optimizing the overall geometry, the double-curvature area at the nose of the roof structure became a special focus. Knippers Helbig Advanced Engineering has managed to minimize the deviation of each single glass pane from the single-curvature geometry to a maximum out-of-plane deformation of only 3 mm. Therefore, the project is a great example of how geometry development can influence structural design and enable new approaches. x | |||||

Petzek, Edward; Schmitt, Victor; Metes, Elena; Ispasoiu, George; Turcan, Alexandru | Romanian projects and integral bridge solutions based on composite dowels | Steel Construction | 3/2016 | 161-169 | Articles |
AbstractThe design and construction of sustainable and durable bridges with low maintenance costs is one of the tasks of road and railway administrations of the European Countries. The structures must be safe, economical and need less maintenance during their service life. All these needs can be found in integral abutment bridges. This solution, which eliminates the bearings and expansion joints, leads to low construction and maintenance costs. Integral bridges also have good earthquake resistance. Bridges are vital structures in the transport infrastructure; it is a fact that, in the last decades, composite bridges have become a popular solution in many European countries as a cost-effective and aesthetic alternative to concrete bridges. Their competitiveness depends on several aspects, such as site conditions, local costs of materials and personnel and the contractor's experience. The main topics of this paper are: design of integral bridges, innovative composite dowels for shear transmission, construction of bridges in Romania, structural analysis of bridges and monitoring. x | |||||
