Experimental and numerical techniques for the assessment of the vibration behaviour of pedestrian structures
Funded by: Ministerio de Ciencia e Innovación y el Fondo Europeo de Desarrollo Regional
Coordinated project: CARTIF, Universidad de Valladolid y Universidad Politécnica de Madrid.
Subproject 1: Universidad Politécnica de Madrid. Investigador principal: Enrique Alarcón Álvarez.
Subproject 2: Cartif y Universidad de Valladolid. Investigador principal: Antolín Lorenzana Ibán
Duration: 2012 to 2014
Goals
- Know the response of slender structures under pedestrian action.
- Apply different modal identification methods (EMA/OMA) to light pedestrian structures.
- Identify and model the actions induced by people on structures.
- To develop a simplified method for the evaluation of the serviceability limit state against vibrations of slender structures for different occupancy levels.
Shaker and pedestrian traffic
Forced excitation using a shaker. Evaluation of the service limit state against vibrations under different types of traffic.
Instrumented templates
Determination of plantar pressures when interacting with the structure.
Modal identification
Techniques for extracting eigenmodes.
PMC Tests
Instrumentation of the Valladolid Science Museum Walkway for testing under environmental excitation.
Tests in G_UPM
Excitement through jumps in the gymnasium of the Higher Technical School of Industrial Engineering of the Polytechnic University of Madrid.
