ANALYSIS OF MEMBER END LOADS ON LAMINATED RUBBER BEARINGS SUBJECTED TO END ROTATION

Abstract

The purpose of this analysis is to show the transition of member end loads of laminated rubber bearings with end rotations and to analyze the stress influenced by displacement and rotation angle. We analyze member end loads of laminated rubber bearings by using a formula that expanded stiffness matrix of laminated rubber bearings are simplified. In this study, analysis is performed by using a coupled model assumed base isolated buildings with inclination of pile top. In addition, we analyze the movement of the inflection point of bending moment distribution of the laminated rubber bearings.
