Abstract

This paper presents the methodology used for the dynamic identification and the vibration serviceability assessment of the 270 m pedestrian footbridge in the Desembocadura del Guadalhorce Natural Park, Málaga, Spain. Designed by Media Madera Ingenieros Consultores S.L., the structure comprises 215 tonnes of glulam timber and almost 15 tonnes of stainless steel, adapted to withstand the marine environment. After its commissioning in 2020, dynamic tests were carried out to estimate its modal properties. Five bending and torsional modes below 3.7 Hz were identified, all with damping ratios above 1.5 % and prone to be excited by the standard pedestrian activity. The resonant pedestrian transits generated peak accelerations of up to 1.0 m/s², with maximum RMS values below 0.60 m/s². These results lead to the conclusion that the structure is fully functional and suitable for its intended use in green space environments.
