The workshop on "Bridge Design to Eurocodes" with worked examples was held on October 4-6, 2010 in the Austrian Federal Ministry for Transport, Innovation and Technology in Vienna. This workshop was the first training event organised at European level for the design of bridges using the Eurocodes. The workshop was organised by Joint Research Centre, CEN/TC210 Horizontal Group Bridges and the Austrian Federal Ministry for Transport, Innovation and Technology and supported by the European Commission DG Enterprise and Industry, CEN/TC250, CEN Management Centre, the Member States and the Austrian Standards Institute. Opening addresses were delivered by Peter Franzmayr, Austrian Deputy Minister for Transport, Innovation and Technology, Manfred Fuchs, European Commission DG Enterprise, Jean-Armand Calgaro, CEN/TC 250 Chairman and Artur Pinto, Joint Research Center.
Objectives
This workshop with emphasis on worked examples contributed towards transfer of background knowledge and expertise of Eurocode Bridge Parts writers (CEN/TC250 Horizontal Group Bridges) to potential trainers at national level and Eurocode users.
The principal objectives of the workshop are to:
-transfer knowledge and information to representatives of key organisations/institutions,
industry and technical associations in Member States;
-provide state-of-the-art training material, background information and worked examples to Eurocodes trainers and users;
-facilitate exchange of views, networking and cooperation.

EN ISO 286:2010 Geometrical product specifications (GPS) - ISO code system for tolerances on linear sizes
EN ISO 286-1:2010 Geometrical product specifications (GPS) - ISO code system for tolerances on linear sizes - Part 1: Basis of tolerances, deviations and fits (ISO 286-1:2010)
This part of ISO 286 establishes the ISO code system for tolerances to be used for linear sizes of features of
the following types:
a) cylinder;
b) two parallel opposite surfaces.
It defines the basic concepts and the related terminology for this code system. It provides a standardized
selection of tolerance classes for general purposes from amongst the numerous possibilities.
Additionally, it defines the basic terminology for fits between two features of size without constraints of
orientation and location and explains the principles of “basic hole” and “basic shaft”.
EN ISO 286-2:2010 Geometrical product specifications (GPS) - ISO code system for tolerances on linear sizes - Part 2: Tables of standard tolerance classes and limit deviations for holes and shafts (ISO 286-2:2010)
This part of ISO 286 gives values of the limit deviations for commonly used tolerance classes for holes and
shafts calculated from the tables given in ISO 286-1. This part of ISO 286 covers values for the upper limit
deviations ES (for holes) and es (for shafts), and the lower limit deviations EI (for holes) and ei (for shafts)
(see Figures 1 and 2).
NOTE In the tables of limit deviations, the values of the upper limit deviation ES or es are shown above the values of
the lower limit deviation EI or ei except for tolerance classes JS and js which are symmetrical about the zero line.
The ISO system for tolerances on linear size provides a system of tolerances and deviations suitable for
features of the following types:
a) cylinders;
b) two parallel opposite surfaces.
For simplicity, and also because of the importance of cylindrical workpieces of circular section, only these are
referred to explicitly. It should be clearly understood, however, that the tolerances and deviations given in this
part of ISO 286 equally apply to workpieces of other than circular sections.
In particular, the term “hole” or “shaft” is used to designate features of the cylinder type (e.g. for the
tolerancing of the diameter of a hole or shaft) and, for simplicity, these terms are also used for two parallel
opposite surfaces (e.g. for the tolerancing of the thickness of a key or the width of a slot).
For further information on terminology, symbols, the basis of the system, etc., see ISO 286-1.

Product Description
Everyday Engineers must solve some of the most difficult design problems and often with little time and money to spare. It was with this in mind that this book was designed. Based on the best selling Mark’s Standard Handbook for Mechanical Engineers, Mark’s Standard Engineering Calculations For Machine Design offers a detailed treatment of topics in statics, friction, kinematics, dynamics, energy relations, impulse and momentum, systems of particles, variable mass systems, and three-dimensional rigid body analysis. Among the advanced topics are spherical coordinates, shear modulus tangential unit vector tension, deformable media, and torsion (twisting).
