Literature of modelling steel frames in 3D using beam finite elements is presented. The development of member modelling is described first followed by joint modelling. The review ends with a brief introduction of the 3D component model for end plate joints. The next part includes three examples of the 3D component method: base bolt joint, beam- to-column joint and member splice joint.

The Emirate of Abu Dhabi is planning for the post-oil era, so education plays a central role in its Master Plan 2030. The new building complex of the Zayed University, intended for 6,000 students, is located in the future Capital District directly on the important connecting road between the Abu Dhabi international airport and the old town peninsular.
Hamburg architects BRT’s (Bothe Richter Teherani) symbolism-rich design moulds the 100.000 m2 GFA ensemble of buildings in the central area into a huge sculpture. The linking element is a jointless free-form roof of 8,000 tonnes of steel with aluminium cladding whose shape and lightness echoes the traditional Arabic chador.
A very short time for design and construction required close cooperation within the international team set up by a main contractor. The project required mastering of numerous engineering challenges, different design philosophies, difficult interfaces between design and construction works on a huge construction site with up to 8,000 workers running in parallel to the design works.

Currently, natural gas with 25 % share of fossil fuels is a very important energy resource. Many gas reserves contain natural gas with a proportion of up to 35 % of hydrogen sulphide (H2S), which can cause hydrogen-induced cracking (HIC).
This paper discusses the development, production and properties of a new steel grade X-COR (eXtra CORosionresistant) for welded pressure vessels, which fit the actual requirements according different standards for pressure vessel steels with up to 355 MPa minimum yield strength very well. The outstanding HIC-resistance is achieved in normalized and stress relieved condition up to a plate thickness of 50 mm. Additionally, important aspects regarding processing behaviour and application of X-COR are highlighted.

The following paper is based on a lecture, hold by Magdalene Weiss (gmp von Gerkan, Marg und partner) and Sven Plieninger (schlaich bergermann und partner) at Tongji University Shanghai on 30th November 2011.

Hybrid girders represent an economical alternative to homogeneous girders because they achieve greater flexural capacity with less material. One of the potential applications of hybrid steel plate girders is their use in bridges. One potential method of construction for these bridges is the push launch method in which patch loading may affect the design. The aim of this paper is to present the advanced conclusions of research work dealing with these two fields simultaneously: hybrid steel plate girders subjected to the particular case of patch loading. It is shown that, contrary to the EN 1993-1-5 formulation, the influence of the fyf /fyw ratio (namely, the hybrid grade) is negligible for both unstiffened and longitudinally stiffened girders according to the EN 1993-1-5 assumptions. Suggestions for considering these findings in design codes are provided at the end of the paper.

This paper presents a new resistance model for steel plate girders subjected to patch loading. The model aims to correct the EN 1993-1-5 formulation concerning the resistance to transverse forces with the help of findings presented in several doctoral studies on this topic. In addition, a statistical calibration of the new model is addressed. This calibration includes a new proposal for the resistance function -. The proposal is conceived for fulfilling safety levels of the partial safety factor that match the current values included in EN 1993 for instability-related problems. These new proposals are in accordance with the design philosophy found in EN 1993-1-5 for the design of plated structures.

The aim of this paper is to study the design requirements for rigid intermediate transverse stiffeners in longitudinally stiffened plate girders. Firstly, two representative design codes, AASHTO and EN 1933-1-5, are discussed and compared. Then the results of two tests on 1.5 m deep plate girders and the results of the extensive numerical parametric study are presented. The analysis of the results shows that the axial force in the stiffener due to tension field action is overestimated in the design codes and that all the design requirements for rigid transverse stiffeners can be covered by defining a minimum required second moment of area.

European standard EN 1993-1-5 provides the effective width method and the reduced stress method as calculation methods for plate buckling assessment. This article focuses on the reduced stress method, for which the global slenderness concept was introduced into EN 1993-1-5. The concept offers advantages associated with today’s numerical procedures which allow the elastic critical load factor of the full stress field to be determined in a single step, thus taking interaction into account in a very elaborate way. However, this article shows that the interaction verification in its pure format based on the von Mises yield criterion is not able to represent the actual mechanical behaviour of biaxially compressed plates. A simple modification is proposed which leads to appropriate and plausible results.

The article reports on how the steel industry in Germany, as a key supplier of materials and innovations to the construction sector, is carrying out a comprehensive optimization of the management of pre-competitive cooperative research (CR) on steel applications in the construction industry. A significant aspect of this is the central use of an innovation broker (IB) role throughout the innovation process. The varying project expectations of science and industry and the related IB tasks are identified as part of an interdisciplinary research cluster on the sustainability of steel in the construction industry. A task profile is drawn up for the IB in cooperative research on the basis of various key person concepts from industrial innovation research. It is expected that the consistent implementation of this profile will increase the innovation successes from CR between the steel industry and the construction sector.
