Application of the Pseudo-Excitation Method with Spatial Coherence in Random Vibration Analysis of Long-Span Space Structures
The pseudo-excitation method is applied for the random seismic response analysis of long-span space structures in this paper. The differences and their orderliness of the structural responses are studied generally under multiple support excitation and simple support excitation from two aspects, i.e. the displacement response variance and the acceleration power spectrum, for four types of structures, such as space truss, shell, cable net and cable dome. Furthermore, the effects of pseudo static response on the above structures are discussed. Some important conclusions are drawn which present the theoretical foundation on aseismatic projects for long span space structures. On the other hand, it shows the pseudo excitation method is efficient and precise and is applicable to the random seismic response analysis of the complicated structure under multiple support excitations, such as long span space truss, shell and cable.
