Abstract
Pedestrian excitation varies at both contact position and amplitude with time. The structural vibration induced by pedestrian excitation may cause human beings’ uncomfortableness, even damage the structures sometimes. A method of analyzing pedestrian excitation concerning human weight, people's step-frequency and escalator velocity is introduced. Concerning both vertical and lateral load effects of human walking simultaneously, the structural dynamic response is analyzed using the Newmark Method. As an application project, the dynamic response of a large-span escalator under pedestrian excitation is calculated and the human comfortableness level is determined.
