Influence of the anchorage shear hysteresis on the seismic response of nonstructural components in RC buildings

Abstract This article presents a numerical study on the influence of anchorage shear hysteresis seismic response nonstructural components (NSC) connected to multi-storey reinforced concrete (RC) buildings, and itself. To cover variety different types shapes, this contribution considered experimental results obtained for five post-installed anchors. The were used calibrating model connecting an ideal NSC with rigid fixture 12-storey RC building host-structure. Using suit 40 earthquake records assuming single at each storey level anchored by fastener, series non-linear dynamic analyses structure-fastener-nonstructural system was carried out. showed significant differences in terms maximum acceleration force anchorage, respectively, depending type anchor. These demands sometimes larger than those required reviewed code provisions NSC, but also most restrictive code-case flexible NSC. presented amounts scatter, mostly related size annular gap loading stiffness anchorage. It is shown that achieved directly peak relative velocity within region. concluded shape highly influences anchor itself should not be neglected practice.
