Abstract:

In this study, a medium scale double layer lattice domes with substructure whose natural period is equal to the natural period of roof structure are made an object of investigation, the effects of yielding of roof members on seismic response behavior of lattice domes are examined by elasto- plastic dynamic response analysis which takes into account the geometrical nonlinearity. In addition, the simplified evaluation method for reductions of seismic response accelerations and

displacements at roof members yielding is proposed. The strain energy produced to the upper structure of equivalent double-mass system based on dome model is used for this evaluation method.
