Fig. 7 Friction pendulum used for the earthquake isolation of the building
For the seismic isolation of the building presented in Fig. 2, we use a friction
pendulum shown in Fig. 7.
Because the contact surface between the sliding and pivotal concave surface is
subject to both frictional and crushing forces, the surface area is given by:
A s = 2 · π · R · h s
(8)
And the crushing pressure is given by:
P ef =
G
N s · A s
(9)
N s the number of the pillars of the buildings.
4 Conclusions
Using the calculation of forces and moments which acts on the friction pendulum,
used for the seismic isolation of the building, we reached to the geometry presented
in the paper.
The simple friction pendulum presented is the optimal solution from a technological and financial point of view. Friction pendulum is more often used because
