Design of Base-Isolated Structure with Rubber-Bearing

摘要

Base isolation design is a new technology on seismic control of structures. In this paper, the theories and steps of base-isolated structure with rubber-bearing design are introduced, then a practical example with isolating rubber-bearings and the corresponding design process are introduced and the simulation results are analyzed.The flexible connecting device of isolation layer design and a connection method of isolation bearing without top fixing plate are introduced. At last, the proposed isolated structure and the non-isolated structure are compared, the result shows the base isolation method can reduce the seismic response of structure evidently.
