127 - Preliminary European Recommendations for the Testing and Design
of Fastenings for Sandwich Panels
The European product standard for sandwich panels, EN 14509, covers the requirements and verification methods for the essential properties of factory made sandwich panel products. Fastenings are typically made at a building site outside the factory. Thus, fastenings are not a subject for a European product standard. The European Recommendations, CIB Publication No. 257 and ECCS Publication No. 115, published in 2000 and 2001, give loading arrangements and proceudures with which to determine the tensile and shear resistance of both direct and concealed fastenings. These new recommendations update the previously published procedures for fastenings and extend the concept to include also fastenings fixed in a face layer.
The sources of information taken into account in the writing of these recommendations have included the previously published recommendations, relevant new research results and the current practice with regard to the available screw fastenings and concealed fastenings. The resulting recommendations are believed to be particularly applicable to the typical metal sheet-faced sandwich panels with cores of polyurethane or polystyrene foam or mineral wool which are on the market today. However, the rules and methods can be applied to other and new types of fastenings and sandwich panel products. When applying these recommendations, the user shall take into account the mechanical behaviour of the fastening in practice and shall take care to ensure the correspondence of the observed behaviour and resistance of the fastening in the tests and the actual behaviour in practice.
The recommendations are published as “Preliminary European Recommendations for the Testing and Design of Fastenings for Sandwich Panels”. There are two reasons for the prefix “preliminary”. The status of full-scale tests, when compared to tests using small-size specimens requires clearer definition. The rules for the adjustment of test results to nomimal values of the essential properties of the face and core materials require more detailed study in order to cover more reliably all types of core materals. Research anticipated in near future may provide the required information and make possible the publication of this document as “European Recommendations”.

N° 123 - Worked examples according to EN1993-1-3
Authors ECCS TC7 TWG 7.5
Eurocode 3, Part 1.3, Supplementary rules for cold formed members and
sheeting (EN 1993-1-3:2004) has been published. This standard replaces
pre-standard ENV 1993-1-3:1996 and contains updates and revisions to
the pre-standard ENV 1993-1-3.
This new publication replaces ECCS document No. 114. The examples have
been updated following the provisions given in EN 1993-1-3. Some new
examples have been also included. These examples show applicability
of design provisions in EN 1993-1-3 in practice. They also help in interpretation
of the guidance given in the code.

N° 118 - Design Examples for the Use of Light Gauge Steel in Steel Framed Housing According to ENV 1993-1-3:1996
English, 2004, 48 pp, Authors TC 7
ISBN 92-9147-000-75
This publication aims at assisting the engineers in applying ENV 1993-1-3 in the design of light gauge steel members in steel framed buildings. It provides engineers examples where basic components of steel-framed house are designed according to ENV 1993-1-3. The examples are based on the Light Weight Steel Framing Manual (1991) published by Canadian Sheet Steel Building Institute (CSSBI) and new Lightweight Steel Framing Design Manual (January 2000) of AISI prepared by Mr. Tom Trestain.

115: European Recommendations for Sandwich Panels Part I: Design
English, 2001, 161 ppThese recommendations apply to roof or wall cladding, ceiling and internal wall panels in the form of a sandwich in which the inner and outer faces are formed from thin metal sheets and the core is a relatively low density material having both stiffening and insulating properties. The components of the sandwich must be bonded together in such a manner as to provide a composite load-bearing panel. Adequate bonding may be achieved by using the inherent bonding capability of certain rigid plastic foams or by the use of separate adhesives. The design equations may only be applied to fully bonded panels. If either face is only partially bonded to the core, all components of resistance must be defined by testing paying due regard to long-term effects.The document as a whole is concerned with structural sandwich panels designed to resist such external loading conditions as wind and snow. For internal construction, less onerous requirements are also formulated.The design of sandwich panels is based on simplified calculation models together with basic material and structural tests. However, the use of more advanced (numerical) methods of analysis and/or full scale testing may be required in certain cases in order to take into account special properties of the panel systems. The use of such advanced methods is outside the scope of these Recommendations.

114 - Preliminary Worked Examples according to Eurocode 3 part 1.3
To check the workability and accuracy of ENV 1993-1-3 it has been decided
by ECCS TC7 to prepare a number of calculations related to cold-formed
structures. The publication of these calculations provides the designing
engineers a number of examples and shows how to handle the different items
in ENV 1993-1-3.

II (Good Practice)
It deals with the application of sandwich components, and is thus principally
directed toward manufacturer and user. Part I contains recommendations
regarding both the dimensioning and fixing of components and includes
statements regarding test procedures for quality control and the determination
of characteristic data of material and carrying capacity values.
