Ingkiriwang, Yohanes Gabriel; Far, Harry | Numerical investigation of the design of single-span steel portal frames using the effective length and direct analysis methods | Steel Construction | 3/2018 | 184-191 | Articles |
AbstractThe era of globalization enables the design, fabrication and erection of steel structures to take place in different locations far away from each other. Therefore, a widely acceptable steel design standard is required, and designers should be familiar with alternative specifications that may be considerably different from one another. This study deals with single-span unbraced steel portal frames and makes a comparison between the design methodologies adopted by the Australian and American design provisions, in particular, the effective length method (ELM) and direct analysis method (DAM). A brief discussion on the main features of both standards is also presented. Furthermore, the results of the parametric study are portrayed, highlighting the differences between these two design standards regarding stress interaction. Finally, of the two aforementioned methods, the most applicable optimization method for the design and development of cost-effective industrial portal frame buildings is proposed with respect to the structure geometry. x | |||||
Lehnert, Tobias | Special heavy plate solutions for bridges | Steel Construction | 3/2018 | 192-195 | Articles |
AbstractIn many European countries, both road and railway infrastructure needs intensive investment to keep up with the growing demands of mobility [1] and goods traffic. Steel or steel-concrete composite bridges offer viable and very sustainable solutions in this context [2]. Owing to its unlimited recyclability, steel can generally be regarded as the ideal material for such sustainable structures. In particular, when designers or fabricators exploit the possibilities of the steel industry available nowadays, very cost-efficient and remarkable structures are feasible. This paper will highlight some of the newest developments in heavy plates for bridge-building. For example, the so-called thick-plate trough bridges have proved to be a favourable concept for small-span railway bridges [3]. Very heavy plates with single plate weights of up to 42 t allow these bridges to be built very efficiently from just one or very few single plates. Another interesting development is the so-called longitudinally profiled plate, which allows the plate thickness to be varied along the actual loading profile. Finally, the benefits of high-thickness thermomechanically rolled plates (TM steel) will be discussed; these offer an ideal solution as the use of higher-strength steels in bridge-building gains more and more ground. x | |||||
Rademacher, Dennis; Ochojski, Wojciech; Lorenc, Wojciech; Ko uch, Maciej | Advanced solutions with hot-rolled sections for economical and durable bridges | Steel Construction | 3/2018 | 196-204 | Articles |
AbstractGrowing problems in terms of damage to bridges correlated with - in some cases huge - long-term impacts on road traffic have shown how essential it is to ensure the durability of the infrastructure and thus the mobility of people as well as the exchange of goods. Corrosion damage can be sustainably avoided in future by employing alternative protection systems for steel and composite bridges. Both hot-dip galvanizing with a coating thickness of at least 200 &mgr;m and weathering steel offer crucial advantages over traditional coating systems when considering the whole life cycle of a bridge: They require no maintenance, and so traffic disruption can be avoided. When using these systems in combination with hot-rolled sections, there are further significant advantages as they render composite bridges more economical and durable, particularly when it comes to short and medium spans. Standard higher strengths with steel grade S460 allow for more economical cross-sections, with weight- and cost-savings of often 20-30 % compared with welded built-up sections in grade S355. Sophisticated designs employing rolled sections can achieve not only small and medium spans, but also longer ones, e.g. arch bridges with spans > 100 m. This article describes new trends in Europe using hot-rolled sections in steel and composite bridges. x | |||||
Haydar, Hussein; Far, Harry; Saleh, Ali | Portal steel trusses vs. portal steel frames for long-span industrial buildings | Steel Construction | 3/2018 | 205-217 | Articles |
AbstractPortal frames and portal truss structures are two of the most cost-effective and sustainable structural forms for the design and construction of long-span industrial buildings. Although the use of both structure types as steel-clad structures is widely accepted, due to frame complexity and variation of frame types for use in single-storey buildings with spans > 30 m, literature providing a comprehensive investigation of the concepts of portal trusses and portal frames is scarce. This study compares the behaviour of a portal truss configuration with pitched portal frames for use in industrial buildings with spans > 30 m, focusing on weight, costs and construction time. Furthermore, this study entails a numerical investigation that utilizes the SAP2000 computer program to model and structurally optimize the member properties for both portal frame and portal truss configurations. Based on the results obtained from the investigation, it has become apparent that, due to the smaller sections used, the portal truss configurations are lighter and cheaper to fabricate and construct in comparison to the pitched portal frames, which, however, require a shorter construction time. x | |||||
Piermarini, Emidio; Nuttall, Hayden; May, Rob; Janssens, Victoria M.; Manglesdorf, Wolf; Kelly, Tim | Morpheus Hotel, Macau - a paradigm shift in computational engineering | Steel Construction | 3/2018 | 218-231 | Reports |

It discusses the tools, methodologies and strategies devised by the engineering team to automate the time-consuming model creation and data-handling operations associated with the finite element analysis, enabling them to complete this challenging part of the project in just 12 months. x | |||||
Rohde, Matthias | Loads on and strengths of amusement rides | Steel Construction | 3/2018 | 232-239 | Articles |
AbstractAll over the world the amusement ride industry is growing steady and all manufactures deliver their products all over the world. This requires a harmonized philosophy of the standards. Today most of the rides are designed to the American Standards of ASTM (F2291-2017) or the European Standard EN 13814. The new revision of EN 13814 passed the formal vote of European members in April 2018. Both committees work close together and the new EN 13814 is in the most important parts harmonized with ASTM F2291. x | |||||

AbstractThe Kazakh pavilion was the heart of the EXPO 2017 in Astana. The ball-shaped construction of steel and glass with a diameter of 80 m had to be designed in a very short time and erected at temperatures as low as -40°C. In the upper part, there are two wind turbines, which contribute to the sustainable energy supply of the pavilion. (Copyright: Andreas Keller, Altdorf, see p. 125) x | |||||

Wardenier, Jaap; Packer, Jeffrey A.; Puthli, Ram | Simplified design equations for Plate-to-CHS T and X joints for use in codes | Steel Construction | 2/2018 | 146-161 | Articles |
AbstractThis paper deals with revised, simplified, consistent equations for plate-to-Circular Hollow Section (CHS) joints for inclusion in codes. After a short review of the background to these resistance equations in the current consolidated version of EN 1993-1-8 and those in ISO 14346, the background to these simplified new equations is discussed. The equations for Plate-to-Circular Hollow Section T and X joints (called TP and XP joints respectively) in the current EN 1993-1-8 are based on experimental data available up to 1991. They are further related to the equations for CHS T and X joints. Most of the data used are based on the ultimate joint resistance. A similar approach is used for the TP and XP equations in ISO 14346, but these are related to the updated equations for CHS T and X joints. x | |||||
