Eave
The line that is usually parallel to the ridge line formed by the intersection of the planes
of the roof and wall.
Eave Gutter
See "Gutter".
Eave Height
The vertical dimension from finished floor to the eave.
Eave Strut
A structural member located at the eave of a building that supports roof and wall
paneling and may act as a strut to transfer bracing loads to frames.
Edge Strip
The surface area of a building at the edges of the roof and at the wall intersections
where the wind loads on components and cladding are greater than at other areas of the
building.
Edge Venting
The practice of providing regularly spaced or continuous openings along a roof edge or
perimeter, used as part of a ventilation system to dissipate heat and water vapor.
Effective Wind Area
The area used to determine the wind coefficient. The effective wind area may be
greater than or equal to the tributary area.
Elastic Design
A design concept utilizing the proportional behavior of materials when all stresses are
limited to specified allowable values in the elastic range.
Electric Operated Crane
A crane in which the bridge, hoist or trolley is operated by electric power.
Electric Overhead Traveling Crane
An electrically-operated machine for lifting, lowering and transporting loads,
consisting of a movable bridge carrying a fixed or movable hoisting mechanism and
traveling on an overhead runway structure.
End Approach
The minimum horizontal distance, parallel to the runway, between the outermost
extremities of the crane and the centerline of the hook.
End Bay
The bays adjacent to the endwalls of a building. Usually the distance from the endwall
to the first interior main frame measured normal to the endwall.
End Frame
A frame located at the endwall of a building that supports the loads from a portion of
the end bay.
End Post
See "End Wall Column".
End Stop
A device attached to a crane runway or rail to provide a safety stop at the end of a
runway.
End Truck
The unit consisting of truck frame, wheels, bearings, axles, etc., which supports the
bridge girders.
End Wall
An exterior wall that is parallel to the interior main frame of the building.
End Wall Column
A vertical member located at the endwall of a building that supports the girts. In beam
and column end frames, endwall columns also support the beam.
End Wall Overhang
The projection of the roof beyond the plane of the endwall.
End Zone
The surface area of a building along the roof at the endwall and at the corners of walls.
Energy Cost
The total estimated annual cost for purchased energy for the building, including any
demand charges, fuel adjustment factors and delivery charges applicable to the
building.
Engineer/Architect of Record
The engineer or architect who is responsible for the overall design of the building
project. The manufacturer’s engineer is typically not the Engineer of Record.
EPDM
Ethylene Propylene Diene Monomer. A Synthetic thermoset rubber that is popular for
membrane roofing and flashings, and as gasketing material for the head of weather
sealing screw fasteners.
Erection
The on-site assembling of fabricated Metal Building System components to form a
completed structure.
Erection Bracing
Materials used by erectors to stabilize the building system during erection.
Erection Drawings
Roof and wall erection (framing) drawings that identify individual components and
accessories furnished by the manufacturer in sufficient detail to permit proper erection
of the Metal Building System.
Erector
A party who assembles or erects a Metal Building System.
Expansion Cleat
A cleat designed to accommodate thermal movement of the metal roof panels.
Expansion Joint
A break or space in construction to allow for thermal expansion and contraction of the
materials used in the structure.
Exterior Framed
A wall framing system where the girts are mounted on the outside of the columns.
