Applications of Trench and Trajectory Friction Pendulum Systems to Seismic Mitigation of Structures
To promote earthquake resistance capability of structures and simply the manufacturing processes of an isolator, two new base isolation systems called the trench friction pendulum system (TFPS) and the trajectory friction pendulum system (TFPS) are proposed and investigated to address their mechanical characteristics and performance in seismic mitigation through a series of shaking table tests in this study. The TFPS isolators can provide different natural periods, displacement capacity and damping effect in any two independent directions. Results from the shaking table tests of a scaled three-story structure isolated with TFPS isolators illustrate that the proposed TFPS isolators can isolate most seismic energy trying to impart to the structure and provide good protection for structures from earthquake damage. In addition, comparisons between experimental results and numerical analyses by the derived mathematical formulation demonstrate that the proposed mathematical model can predict the response of a structure isolated with TFPS isolators with high accuracy.
