Congreso celebrado en la Escuela de Arquitectura de la Universidad de Sevilla desde el 24 hasta el 26 de junio de 2015.Response for the static, modal and dynamic problem corresponding to a stress ribbon footbridge is
studied. The equilibrium equations describing the problem are coupled nonlinear differential
equations which are numerically solved using the finite element method. The objective of this work is
to present a proper computational model for such a structure and to check its applicability in
predicting not only the static behaviour but also modal parameters and estimate its dynamic
response. As the footbridge is continuously monitored, it has been possible to measure the sag and
to identify natural modes. This experimental data has been used for updating the finite element
model
