Seismic safety
velocity-dependent energy dissipation devices (EDD
Construction; Seismic safety
Devices having mechanical characteristics such that the force in the device is dependent on the relative velocity in the device.
v-braced frame
Construction; Seismic safety
A concentric braced frame (CBF) in which a pair of diagonal braces located either above or below a beam is connected to a single point within the clear beam span. Where the diagonal braces are below ...
unreinforced masonry (URM) wall
Construction; Seismic safety
A masonry wall containing less than the minimum amounts of reinforcement as defined for masonry (RM) walls. An unreinforced wall is assumed to resist gravity and lateral loads solely through ...
ultimate bearing capacity
Construction; Seismic safety
Maximum possible foundation load or stress (strength); increase in deformation or strain results in no increase in load or stress.
transverse wall
Construction; Seismic safety
A wall that is oriented transverse to the in-plane shear walls, and resists lateral forces applied normal to its plane. Also known as an out-of-plane wall.
timbers
Construction; Seismic safety
Lumber of nominal five or more inches in smaller cross-section dimension.
tie-down system
Construction; Seismic safety
The collection of structural connections, components, and elements that provide restraint against uplift of the structure above the isolation system.
