- Company Profile:
A structural system included in buildings with the following features:
* An essentially complete space frame provides support for gravity loads.
* Resistance to lateral load is provided by concrete or steel shear walls, steel eccentrically braced frames (EBF), or concentrically braced frames (CBF) along with moment-resisting frames (Special Moment Frames, or Ordinary Moment Frames) that are capable of resisting at least 25% of the lateral loads.
* Each system is also designed to resist the total lateral load in proportion to its relative rigidity.
Industry:Construction
Structures wherein the maximum equilibrium moisture content does not exceed 19%.
Industry:Construction
The dimensions of lumber after surfacing with a planing machine. Usually 1/2 to 3/4 inch less than nominal size.
Industry:Construction
A component parallel to the applied load that collects and transfers diaphragm shear forces to the vertical lateral-force-resisting components or elements, or distributes forces within a diaphragm. Also called collector, diaphragm strut, or tie.
Industry:Construction
Includes bolts, lag screws, wood screws, nails, and spikes.
Industry:Construction
The maximum compression strength of wood or wood-based products when subjected to bearing by a steel dowel or bolt of specific diameter.
Industry:Construction
Devices having mechanical properties such that the force in the device is related to the relative displacement in the device.
Industry:Construction
Collection of structural components and elements that limit lateral displacement of seismically-isolated buildings during the BSE-2.
Industry:Construction
The total movement, typically horizontal, of a component or element or node.
Industry:Construction
