Abstract

The principle of isolating a structural system ITom ground motion has been understood for many years, whereas numerous successful implementations have been applied in bridges or buildings that are mounted as a bearing. One of these devices appears as the laminated steeVelastomer bearing. Structural Earthquake Engineering Research (SEER) has being developing the hollow base isolator in order to reduce the horizontal stiffness of the isolator and to increase the effectiveness of the original one. The existing advanced computer programs used a finite element method based on the mechanic behaviour of elastomeric bearing under compressions and shear loads. The previous programs assumed the isolator as an elastic material. In contrast, the isolator is made ITom elastomeric rubber bearing which is not an elastic material. Therefore, the previous programs should be clarified or modified to obtain more reliable results. This paper describes the aspects of this research
