Note: Steel connections are assemblies that include, but are not limited to, welds, bolts, rivets, angles, and plates. Reinforced concrete connections are often integral, consisting of the concrete and the reinforcement at the end of one component and extending into the other.
Ductile connection — a connection that is capable of experiencing significant inelastic deformation before failure.
Daylight (unattached) film configuration — a film that is applied to the face of the glazing but not to the window frame.
Notes:
1) Daylight film application is only suitable for blast loads marginally larger than those required to foil the gloss, the pane (including the gloss and film) would be projected into the building as one large sheet rather than many small fragments.
2) Da ylight film applications do not significantly increase the loading on the window frame and structure, as the failure mechanism is still based on fracture of the glazing.
3) Daylight film applied to the inner pane of on insulated glass unit will not contain the glass fragments that are generated by the outer pane during a blast event.
Deflagration — a combustion reaction of a substance in which the reaction front advances into the unreacted substance at a speed that is less than the speed of sound in the unreacted material.
Deformation-controlled action — a load effect, such as moment, shear, or axial force, that results in ductile behaviour for a particular structural component type.
Design basis threat (DBT) — the threat that the building owner and/or the AHJ have determined from their threat assessment and/or available intelligence that will be used to determine the blast loads for the design and assessments of the building in question.
Detonation — a combustion reaction of a substance in which the reaction front advances into the unreacted substance at or greater than the speed of sound in the unreacted material.
Diaphragm — a horizontal or nearly horizontal structural system that acts to transmit lateral forces to the vertical resisting components.
Disproportionate collapse — a degree of structural collapse that is disproportionately large as compared to the loading event that initiated it, typically caused by a progressive collapse scenario.
Door — see Door system.
Door system — one or more leaves or panels contained within one master frame with a sill/threshold and with or without mullions or hardware. The operable panels are hinged or sliding. The hinged panels can swing inward or outward.CSA S850-12 pdf free download.
