and displacements and therefore it is superior than other arrangements as a comparison to show the effectiveness of the functional switches as applied to the structure the same el centro earthquake record is used to calculate the displacement response of the frame with the functional switches applied it can be seen from fig1 a that the peak value of the displacement response is now 0 7 cm which is about 1 700 of the frame height this is a 70 improvement over the results shown in fig1 and it agrees with the preliminary design also to illustrate the difference between using simple bracing and the functional switches another treatment of the frame with simple bracing of 100 original stiffness is studied the corresponding displacement is given in fig1 b it is seen that the peak displacement is only reduced to about 1 6 cm this improvement is less than 20 while calculated results are shown in fig1 15a and 15b actual results comparable to those shown in fig1 and 15a are shown in fig1 in the application just discussed in connection with the structure shown in fig1 and 13 the functional switches have been used to dissipate energy and to modify the stiffness of the structure in a single plane however it should be obvious from fig3 that the functional switches may be used to dissipate energy in more than a single plane thus the functional switches 36 3 and 36 4 lie in differing planes.
