Seismic Response Analysis and Test of Derailment of Container Crane

Abstract

The 1995 Hyogoken Nanbu Earthquake caused enormous damage to Container Crane of Kobe Harbor. It was reported that a behavior of container crane under strong earthquakes involved uplifting and slipping of their legs. However, such behavior is not taken into consideration in the seismic design of crane, because of difficulty due to its nonlinearly. The purpose of this study is to establish the method of the seismic design of container crane by verifying the analysis method which are compared the result of vibration test of 1/15 scale model. This report describe the seismic isolation method to make verification by the nonlinear transient analysis of 3-D FEM model and vibration test.
