THE BENEFIT OF UPLIFTABLE STRUCTURES IN EARTHQUAKES
Observations in the past major earthquakes have shown that partial uplift had been beneficial to some structures.The temporary separation and the reconnection of part of interface between footing and the supporting ground can reduce the forces activated in structures.However,in conventional design of structures uplift is still considered as a potential of structural collapse and thus should be avoided.An acceptance of uplift is further impeded by the intrinsic complexity of the involvement of nonlinear soil-foundation-structure interaction that often occurs in strong earthquakes.This paper briefly presents research on the development of upliftable structures.Some factors that influence the uplift behaviour of structures are discussed using results obtained from shake table experiments with a model structure.
