چکیده مقاله
Among different types of space frames, single layer diamatic dome SLDD is superior structure that provides cost effective solution to cover the large areas without intermediate supports Since changes on the geometry play a key role in the structural response of space frames, in this paper effects of applied pellevation with different geometries on improving seismic performance of SLDDs are studied For this purpose, one group includes simple SLDDs with different ratio of rise to span has been created, and then different types of pellevation are applied to the first group in the three groups The nonlinear dynamic time history analysis is performed for the defined groups and the structural behavior of different systemshas been compared The results show desirable effects on weight reduction of pellevated domes while the structural performance is improved It is obtained that the weight of the dome can be reduced by about 16% via choosing a proper pellevation
