This report is a part of activities for the maintenance, further harmonisation, further development and promotion of the Eurocodes. It has been prepared in a field where so far no unified design rules applicable across different materials and ways of construction exists in the Eurocodes, namely in the field of limiting human induced vibrations of foot bridges.
It is a contribution to the evolution of EN´s 1990 and 1991 and may also be used together with some specific rules in EN 1995-2 that apply to timber bridges as a source of support to
- further harmonize design rules across different materials, and
- further develop the Eurocodes.
The rules for the “Design of lightweight footbridges for human induced vibrations” given in this report are the result of projects funded by the Research Fund for Coal and Steel (RFCS), initiated and carried out by a group of experts from RWTH Aachen, Germany, Arcelor Mittal Luxembourg, TNO, The Netherlands, SCI, United Kingdom, CTICM, France, FEUP Porto, Portugal and Schlaich, Bergermann und Partner, Stuttgart, Germany.
The agreement of RFCS and of the project partners to publish this report in the series of the “JRC-Scientific and Technical Reports” in support of the further development of the Eurocodes is highly appreciated.
The examples given in this guideline are mainly from light-weight steel structures, where the consideration of human induced vibrations is part of the optimization strategy of the structure. Therefore the publication has been carried out in the context of the JRC-ECCS-cooperation agreement in order to support the further harmonisation of National procedures and the further evolution of the Eurocodes.
