Steel Structures and Eurocodes

Economics of Steel framed buildings in Europe (ESE)

The objective of the project is to provide practitioners with a web-based tool to enable them to develop cost-effective design solutions for steel-framed buildings and to enable economic comparisons to be made. It is achieved by providing guidance to designers on the parameters that affect building cost, as well as the tool to calculate the aggregate costs. The tool can also support designers in convincing decision makers and investors to work with steel in commercial, industrial and residential sectors. It leads to a greater understanding of the economics of steel construction in buildings.

Human induced vibration of steel structures

The objective of this project is the dissemination of knowledge gained in two European research projects. The two research projects deal both with human induced vibration of Steel Structures, a design problem that becomes more and more relevant as structures are more slender if high strength steels are applied.
For the dissemination the conclusions of the research projects - draft guidelines for vibration design of floors and footbridges - will be merged into one guideline and a accompanying background document for vibration design. The resulting guideline would be the first European guideline for vibration design of structures.

"PrECO-Beam" Prefabricated Enduring Composite Beams based on Innovative Shear Transmission

Composite structures are gaining in importance in Europe. The combination of materials within its specific properties results in very slender and economic constructions. Composite girders permit large spans in slender frame bridges without loss of economy. Due to the high grade of prefabrication in building construction smaller survey heights and shorter construction times are possible. The enduring bearing capacity of composite girders depends on the performance of material and the design of shear connection. A new form of shear transmission - the concrete dowel - permits composite girders without an upper steel flange and an enduring shear connection also of high strength steel with high strength concrete. see more

"Robustness" Robust structures by joint ductility

"PRECIOUS" Prefabricated composite beam-to concrete filled tube or partially reinforced-concrete-encased column connections for severe seismic and fire loadings

The project has analysed, from both an analytical/numerical and an experimental standpoint, the scenario in which a fire follows an earthquake, thus defining joint typologies for which, after being damaged by an earthquake, a residual load-bearing capacity is assured during a fire occurring after an earthquake. The design has been performed in the modern context of performance-based engineering. Both interior and exterior joints with partially reinforced-concrete encased columns, i.e. type 1 joints, have been designed to be semi-rigid and partial strength, and to exhibit high ductility and limited strength deterioration under severe seismic loadings.

"COSIMB" Composite Column and Wall Systems for Impact and Blast Resistance

Based on the experimental and analytical findings, design approaches are proposed at two distinct levels, one for advanced application and another which is more suited to idealised engineering treatments. Overall, this research substantiates the favourable and synergetic capabilities of composite members in resisting extreme loads, and puts forward verified approaches for their application in practice.

"INPREST" Integrated Pre-fabricated Steel Technologies for the Multi-Storey Sector

Modern steel buildings require a high degree of pre-fabrication and effective integration of key components. The concept of open building systems in steel is developed with a focus on the multi-storey residential sector. The research will lead to the development of new systems involving skeletal, planar and modular components, including supporting design information.

Modelling and Predesign of Steel and Composite Structures

Nowadays in engineering offices usual pre-design is still often based on the allowable stress method instead of the more efficient limit states method prescribed by Eurocodes 3 and 4. In order to satisfy the needs of engineering offices, the intention of this research project was : - to develop guidance on the basis of Eurocodes for structural modelling, for global analysis, for checks of members, etc.; - to prepare practical tools (software in particular) for pre-design of steel structures and composite steel-concrete structures according to Eurocodes 1, 3 and 4 respectively, in function of different decisive parameters: the type of rigidity allocated to the structure (i.e. rigid or sway buildings), the type of joints, etc.

Partial Safety Factors for Resistance of Steel Elements to EC3 and EC4

The first objective (γMO) is addressed by measurement campaigns in steel mills for hot-rolled product characteristics (dimensions and yield strength). Those measured values are used to compute resistances, wich are compared with resistances resulting from the nominal values. A statistical analysis of deviations results in safety factors. The results are quite satisfactory, a value of 1.0 being justified.

Design Handbook for Braced Composite Steel-Concrete Buildings according to Eurocode 4

The present publication is intended to be a design aid in supplement to the complete document Eurocode 4 - Part 1.1 (always with references to it) in order to provide simplified guidance and to facilitate the use of Eurocode 4 for the design of such composite steel-concrete structures which are usual in common practice: braced composite steel-concrete structures. As this handbook is less formal and more user-friendly than Eurocode 4 additional information have been introduced to offer explanations on design principles or application rules and, about usual design results.

Therefore, the “Design handbook according to Eurocode 4 for braced composite steel-concrete buildings” presents the main design formulas and rules extracted from Eurocode 4 - Part 1.1, which are needed to deal with:

- elastic global analysis of buildings and similar structures,

- checks of structural members at limit states,

- in case of braced structures,

- according to the European standard Eurocode 4 - Part 1.1 (ENV 1994-1-1:1992).

Design Handbook for Braced or Non-Sway Steel Buildings according to Eurocode 3

The present publication is intended to be a design aid in supplement to the complete document Eurocode 3 - Part 1.1 in order to facilitate the use of Eurocode 3 for the design of such steel structures which are usual in common practice braced or non-sway steel structures.

Therefore the “Design handbook according to Eurocode 3 for braced or non-sway steel buildings” presents the main design formulas and rules extracted from Eurocode 3 - Part 1.1, which are needed to deal with:

- elastic global analysis of buildings and similar structures in steel,

- checks of structural members and connections at limit suites,

- in case of braced or non-sway structures,

- according to the europcan standard Eurocode 3 - Part 1.1 (ENV 1993-1-1).
