Peak Sliding Demands on Unanchored Equipment and Contents in Base-Isolated Buildings under Pulse Excitation

Unanchored equipment and contents (EC) in buildings are of primary concern during an earthquake because not only can they contribute to substantial nonstructural losses but also pose a serious safety risk to building occupants. Base isolation is widely considered to be an effective technique for reducing seismic demands on nonstructural components, but recent research has noted situations, under broadband ground motions, where isolating a …
