Abstract
As a typical base isolation device, the friction pendulum bearing (FPB) was applied to the lattice grid structures in this paper. The isolation mechanism of FPBs was analyzed from two aspects of force and energy consumption, while the static and dynamic mechanical properties of lattice grid structures with FPBs were numerically investigated using two models of regular and oblique quadrangular pyramid framed structures. The physical models of FPBs with fictional coefficient of 0.1 and a curvature radius of 1.0 m was established and applied to the lattice grid structures. Moreover, the mechanical properties of these structures with FPBs ware studied. Numerical results indicate that the seismic response of structures is remarkably weakened by using FPBs, which means FPBs can be used to effectively control structural vibration.
