Abstract

 The seismic performance of a multiple steel pipes bridge pier integrated by pile foundation without a footing is evaluated both experimentally and analytically, and a design method using a “beam-spring” frame model with columns and pile foundations as an integrated structure is proposed. On the other hand, in the field of road bridge foundations, research has been conducted for some time to take into account the variation of geotechnical properties due to differences in soil types and geotechnical investigation methods in design methods.

 In this paper, the effects of geotechnical uncertainties on the design of a multiple steel pipes bridge pier integrated by pile foundation without a footing are evaluated and compared with those of conventional RC piers and steel piers. The results show that the influence of the ground variation is comparable to that of the conventional pier type.
