Research on Seismic Response Calculation Method for Rocking Column

Abstract

Damage investigation showed that the rocking column structures, such as stone pillars and Petroleum cracking towers, are easier rock, even collapse, under big earthquake. Focusing on this type of rocking column structure, their seismic responses are analyzed, in which the soil-structure interaction is considered by contact elements. And the results of the calculation and shaking table test results were compared and analyzed. Research results showed that: (1) The frequency characteristics of the model established in this paper are consistent with the experimental data, which can be used for the subsequent transient analysis; (2) Although the calculation results in amplitude is slightly different with the test results, seismic response rules between calculated results and the experimental results are consistent each other z1on the whole, which indicates that the calculation method used in this paper is reasonable. The research results in the paper can provide some references for seismic design of rocking column structure.
