Buildings, 2023 Since the well-known Millennium bridge accident happened at the beginning of this century, both researchers and engineers realized that the human-induced vibration may lead to unaffordable consequences. Although such vibrations hardly threaten the safety

A general vibration control methodology for human‐induced vibrations [PDF]
Structural Control and Health Monitoring, 2019 This paper proposes a general methodology for the design of vibration control of human-induced vibrations. This uses a feedback loop for the design of control parameters and accounts for the nature of human excitation and how humans feel the vibration.

Evaluation of human-induced vibration of continuous footbridges [PDF]
MATEC Web of Conferences, 2015 With the development of construction materials and the introduction of high strength steel and concrete, the human-induced vibration became a dominant criterion for the design of pedestrian bridges.

Acceleration feedback control of human-induced floor vibrations [PDF]
Engineering Structures, 2010 Active vibration control (AVC) via a proof-mass actuator is considered to be a suitable technique for the mitigation of vibrations caused by human motions in floor structures. It has been observed that actuator dynamics strongly influence structure dynamics despite considering collocated actuator/sensor control.

Equivalent Dynamic Load Factor of Different Non-Exceedance Probability for Crowd Jumping Loads
Buildings, 2022 Existing dynamic load factors (DLF) for crowd jumping loads are modeled by identifying the peaks and energies from the corresponding Fourier amplitude spectrum, which may underestimate and overestimate structural responses, respectively.

A Fourier Series-Based Multi-Point Excitation Model for Crowd Jumping Loads
Buildings, 2023 Crowd jumping loads are often simplified to a single-point excitation in the existing Fourier series-based models, most of which lack the data support of crowd jumping experiments.
