Eave

The line along the sidewall 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 (the line along the sidewall formed by intersection of the planes of the roof and wall).

Eave Strut

A structural member located at the eave of a building which supports roof and wall paneling.

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.

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 end-walls of a building. Usually the distance from the end-wall to the first interior main frame measured normal to the end-wall.

End Frame

A frame located at the end-wall of a building which 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 which is parallel to the interior main frame of the building.

End Wall Column

A vertical member located at the end-wall of a building which supports the girts. In beam and column end frames, end-wall 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 end-wall and at the corners of walls.

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.

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 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.
