The enthusiastic behavior 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 behavior of pedestrian bridges in the vertical direction...
