dc.description.abstract | The enthusiastic behaviour of people on structures can cause synchronized rhythmic movements which may lead to
resonance between forcing frequency and one or more natural frequencies of the structure. Such a human-structure
synchronization results in strong vibrations that affect structural stability and create discomfort among people. The
Indian codes and standards do not consider Crowd-Structure Interaction (CSI), resulting in an unreliable vibration
assessment of structures. The present work investigates the effect of CSI on the dynamic behaviour of pedestrian
bridges in the vertical direction. The system is modelled as a two degree of freedom mass spring damper system and
the modal properties are determined. The modal properties and response of the system are studied for varying crowd
parameters such as size and location. A probabilistic sensitivity analysis is carried out to understand the sensitivity of
modal properties and response of the CSI system to the parameters of crowd and empty structure, using a variance
based method. Monte Carlo simulation is used to simulate samples of the random parameters. Crowd activity frequency
and generated load factor are observed to be the most sensitive parameters affecting the vibration of the structure. | en_GB |
