Influence of Multiple Earthquakes on Single-Layer Reticulated Dome and Its Shaking-Table Test

Abstract In this paper, a primary dataset of mainshock–aftershock sequences is constructed from the Pacific Earthquake Engineering Research Center. This is followed by the collection of 342 groups of mainshock–aftershock ground motions for the dynamic time history analysis of a single-layer reticulated dome in the full process domain. According to the change curves between the characteristic factors and acceleration amplitudes, four different levels of influence (i.e. no influence, slight influence, significant influence and collapse under aftershocks) of multiple earthquakes on the seismic responses of a single-layer reticulated dome are defined. On this basis, a shaking-table test of a single-layer reticulated dome model, taking aftershocks into consideration, is conducted to obtain the full failure history under multiple earthquakes intuitively. Spherical joints are located accurately, using total station surveying equipment and lead screws during model processing. Experimental results verify the above four levels of influence of multiple earthquakes and provide a dependable reference for seismic design.
