Company Profile:
The value of the lateral force in the isolation system, or an element thereof, divided by the corresponding lateral displacement.
Industry:Construction
The value of equivalent viscous damping corresponding to energy dissipated during cyclic response of the isolation system.
Industry:Construction
A diaphragm or shear wall boundary element parallel to the applied load that collects and transfers diaphragm shear forces to the vertical-forceresisting elements or distributes forces within the diaphragm or shear wall. A drag strut often is an extension of a boundary element that transfers forces into the diaphragm or shear wall.
Industry:Construction
A collection of structural elements that limits lateral displacement of seismically isolated structures due to maximum considered earthquake ground shaking.
Industry:Construction
The maximum considered earthquake lateral displacement, including additional displacement due to actual and accidental torsion, required for verification of the stability of the isolation system or elements thereof, design of structure separations, and vertical load testing of isolator unit prototypes.
Industry:Construction
The design earthquake lateral displacement, including additional displacement due to actual and accidental torsion, required for design of the isolation system or an element thereof.
Industry:Construction
The design earthquake lateral displacement, excluding additional displacement due to actual and accidental torsion, required for design of the isolation system.
Industry:Construction
A diaphragm boundary element perpendicular to the applied load that is assumed to take axial stresses due to the diaphragm moment in a manner analogous to the flanges of a beam. Also applies to shear walls.
Industry:Construction
A location where shear is transferred into or out of the diaphragm sheathing. Transfer is either to a boundary element or to another force-resisting element.
Industry:Construction
A diaphragm in which all sheathing edges not occurring on a framing member are supported on and fastened to blocking.
