Analysis about Isolation Effect for Mega Frame with Rubber Bearing

Article Preview

Abstract:

According to Lagrange equation in dynamics the motion equation of the mega frame with rubber bearing isolation was established. Its solution was approched with MTALAB language programming. The calculation results show that the seismic isolation system can significantly reduce the seismic dynamic response of inter-story drift. When the first layer support and the second support stiffness coefficient of rubber bearing being 190000 kN/m, and the equivalent damping coefficient being about 20000kN.s/m, the isolation efficiency can reach as high as 50%~88%, which is the best combination.
