examining the effective parameters of fuse in seismic behavior of low damage steel-braced frame systems

Past earthquakes experiences identifies the need for buildings which are less vulnerable to damage and easier to repair after a major earthquake. applying new types of structural systems which is known as low damage systems is promoted in framework of a resilience based design. these systems include components of rocking able frame, replaceable fuses and vertical post tensioning tendons to return the structure to its initial state. low damage system is a resisting system with high performance against earthquake. an important class of this systemhas controlled rocking frames and replaceable fuses that is combination of conventional steel braced frame characteristics and energy dissipating devices.
