With the development of demand of exploiting offshore oil reserves, the Jacket platform structure’ span and depth is more and more large, so the seismic analysis of the jacket structure will become more and more complicated. In the dynamic analysis of long-span structures, multiple support excitation may be accounted is necessary. For big jacket structure, it is more accurate and reasonable by multiple support excitation than by uniform excitation. The objective of the research described herein is to develop a simplified method to investigate the effect of multiple support excitation on the jacket structure.

The effect of incoherency of seismic waves and wave travel on the displacement and force response of jacket structure are investigated from the maximum force, reaction force, the displacement, and so on. The conclusions illustrate it is necessary to consider the effect of multiple support excitation. The research of the differences of seismic response under multiple support excitation from uniform excitation presents the theoretical foundation on aseismatic projects for long span space structures such as jacket.

Random Seismic Response

Based on the orthogonal expansion method of stochastic processes, seismic acceleration processes can be represented as a linear combination of deterministic functions modulated by a set of mutually independent random variables. In conjunction with the probability density evolution method, the random seismic response of bridge structures can be successfully researched. A long-span bridge structure is taken as an example. The probabilistic information of the response of a long-span bridge structure in different control under earthquake excitations is investigated. The investigation provides a new approach to the random seismic response analysis of long-span bridge structures.
