| Abstract: | Based on existing researches on pedestrian loading and comfort level assessment, different pedestrian loading models are developed to simulate activities of single person walking, regular or stochastic crowd walking. Vibrating characteristics and comfort level of long span steel corridor are studied. According to the vibrating characteristics of structures, an MTMD system is designed in the corridor using the relevant results. It is shown that the design of the MTMD system can control the vertical vibration of the corridor and can satisfy the requirement of the comfort level. |
