  • In order to research the critical apparent wave velocity of long-span spatial structures considering traveling wave effect, the time-history method was used to investigate the seismic response of double-layer cylindrical latticed shells with different structural styles and geometric sizes under multiple-support excitation with kinds of apparent wave velocities and single excitation. The results showed that the traveling wave effect with any apparent wave velocity had no obviously disadvantaged effect on transverse and web members, but had a great disadvantaged effect on longitudinal members, in which the internal force was small at the bottom chord and large at the top chord. Changing the spacing of supports had little effect on the traveling wave effect, while the effect of apparent wave velocity on the traveling wave effect was related to the structural style and geometric sizes and so on. It was concluded that only the longitudinal members at the top chord were needed for the research of the traveling wave effect, and the critical apparent wave velocity of any structure considering traveling wave effect should be analyzed separately.
