Effects of Deformation of Slab in One－Storeied Structure on Lateral Force Distribution:Symmetrical Structure without Walls of Longitudinal Direction

摘要

In this paper the definitions of technical terms are as follows：longitudinal direction：direction perpendicular to the direction of action of the lateral forces.transverse direction：direction of action of the lateral forcesrigid walled－frames：rigid frams with waIlsIn buildings，in which rigid frames and rigid ones with walls are provided，both bending and shearing deformations of the slab between rigid walled－frames will be caused in the horizontal direction by lateral forces such as the seismic force if the distance between those frames is long，and the rigid frames situated in the middle part between two rigid walled－frames will deflect more than those near the ends and，consequently，the lateral forces carried by the former become larger．Therefore，the lateral force distribution method based on the conventional assumption that slabs are perfectly rigid can not be accepted in structural design．
