Self centering mechanisms
WebWhile considering self-centering base-shear mechanisms only, the differences in the mean absorbed energy E ¯ a b s ${\bar{E}}_{abs}$ between a mechanism with β V ${\beta }_V$ = 0.6 and with β V ${\beta }_V$ = 1 are minimal in most cases, suggesting that structures with β V ${\beta }_V$ = 0.6 exhibit similar energy dissipating capacity as ...
