There is a new trend to allow uplift in structures to have maximum energy dissipation during
strong ground motion. This aspect needs to be studied in detail, particularly in three …

Uplift has been used as a mitigation measure to reduce lateral forces in structures. Previous
studies had focused mainly on the effect of single column uplift with complex mechanism …

In design of structures for applied loads, the common assumption is that the structure is
tightly attached to its base, ie no vertical rigid-body motion can happen at the same place …

Allowing structures to uplift in earthquakes can significantly reduce or even avoid the
development of plastic hinges within the structure. The permanent deformations in the …

In this paper, dynamic behavior of buildings allowed to uplift at mid-story is investigated. The
system considered is a two dimensional uniform shear-beam model allowed to uplift at mid …

Recent investigations showed that minor structural uplift could act as a control mechanism
and reduce the earthquake impact. Previous studies focused mainly on the effect of uplift on …

The effects of rocking vibration accompanied by uplift motion may reduce seismic damage to
buildings. Structural systems that are allowed to uplift can be recognized as one of the …

Previous research has shown that footing uplift can reduce the strength demand of structural
members in strong earthquakes. However, foundation uplift is normally excluded in …

In current seismic design concept, earthquake energy in the structure can only be dissipated
by the material damping and the plastic deformation of structural members. If a structure is …

The effect of base uplift on the maximum response of single-degree-of-freedom (SDOF)
structures is examined in this paper. A parametric investigation performed for the case of a …
