| Abstract: | The seismic isolation spherical bearing that used for the fourth Qianjiang bridge is the largest one in Asia with its bearing capacity greatly exceeding the scope which is specified under the "Technical Specifications for Spherical Bearing".This article studied on the large tonnage seismic isolation spherical bearing of the fourth Qianjiang bridge by finite element analysis through the static force calculation,modal analysis and dynamic analysis ,to find out the interaction pattern between the elements to guarante the reliability of the bearing.It is concluded that the stress and strain of the main members meet with the specification. |
