Abstract

A space frame structure with consistence mass system having six degrees of freedom (three translations along x, y, z-axes and three rotations about these axes) at each node resting on laminated rubber bearing and subjected EI Centro earthquake ground motion is analysed. A step-by-step Newmark method is adopted to solve the equation of dynamic equilibrium. The response of structure isolated at base is compared with the response of the structure fixed at base. The response of isolated system is found to be less in comparison to the corresponding response without isolation system, implying that the isolation is effective in reducing the response of the structure.
