Dynamic response of floors due to people in motion

The interaction between the supporting structure and the dynamic forces generated by people in motion is presented. The dynamic loading from people activities such as walking, running, jumping, etc. is described by means of dynamic load factors at harmonics of the step frequency. Dynamic load factors are presented for a range of activity rates. The dynamic response of floor structures to such loading is briefly discussed and design guidelines for floors are given.Les auteurs font \ue9tat de l'interaction de la structure de soutien avec les forces dynamiques produites par le mouvement humain. Il d\ue9crivent, \ue0 l'aide de coefficients de charge dynamique dans les harmoniques de la fr\ue9quence du pas, les charges dynamiques r\ue9sultant d'activit\ue9s de charge dynamique r\ue9sultant d'acitivt\ue9s humaines comme la marche, la course, le saut, etc. Ils pr\ue9sentent les coefficients de charge dynamique pour une plage de fr\ue9quences d'activit\ue9s. Ils examinent bri\ue8vement la r\ue9ponse dynamique des planchers \ue0 ces charges et fournissent des lignes directrices pour le calcul des planchers.Peer reviewed: YesNRC publication: Ye
