Review Of Live Loads Due To Human Movements, William Saul, Christopher Tuan
Review Of Live Loads Due To Human Movements, William Saul, Christopher Tuan
Christopher Y. Tuan
Present U.S. structural engineering practice assumes that live load components due to human occupancy and human movements for the design of assembly structures, such as grandstands, can be represented as statically applied uniform or line loads. A review of code values and procedures reveals a history of theoretical, experimental, empirical, and practical developments and events that provide insight into their sources and meanings. The mechanisms by which they have been implemented should prove to be interesting and informative to the design engineer and others concerned with the modernization of codes. The designer is provided with a perspective of a complex …
Loads Due To Spectator Movements, Christopher Tuan, William Saul
Loads Due To Spectator Movements, Christopher Tuan, William Saul
Christopher Y. Tuan
Typical spectator movements were simulated by persons individually on a force platform with which dynamic force components were measured. Impulsive loadings are produced by movements such as rising, sitting, or jumping off the floor, while continuous loadings are generated in repetitive motion such as swaying, bending and straightening knees repetitively in place, jumping or dancing. Descriptive parameters derived from statistical and spectral studies of the load samples are presented. In particular, the vertical components of the impulsive loadings are modeled as random forcing functions, and a narrow‐band live load spectrum is proposed for checking potential resonant response of a structure …
