Abstract

In the present paper the effects of differential earthquake motions at supports, which are assumed to be caused by wave passage and local site, on the seismic responses of a large-span reticular dome are checked in several cases. The calculated results show the seismic responses of the dome are reduced by the wave passage effect due to the loss of coherency. On the other hand, the seismic responses of the dome increase because of the additional wave transmission caused by the local site effect. The differential support motions do also influence the internal forces generated in the substructure and foundation as revealed based on the analysis. These obtained data provide the useful information for the design practice of large-span structures to consider the effects of spatial variability of support motions.
