| Abstract: | On the basis of the time history response of long-span space lattice structures under multiple support excitation, The rule of pseudo-static displacement distribution in structure is summarized, which is related to seismic actions in different directions and different apparent wave velocity, moreover, the relation between apparent wave velocity, span and pseudo-static displacement is studied. |

| Keywords: | multiple support excitation long-span space lattice structures pseudo-static displacement |
