A portal frame steel building under construction. Portal frame is a construction technique where vertical supports are connected to horizontal beams or trusses via fixed joints with designed-in moment-resisting capacity. [1] The result is wide spans and open floors. Portal frame structures can be constructed using a variety of materials and ...
The II-shaped frame, the inside of which forms the obverse surface, tympanum, and ktoba, is finished with an inscription above the lancet arch. The northern part of the niche portal is a limited gable wall with a doorway.

An anchor portal or H-frame tower is a gantry structure supporting overhead power lines in a switchyard. Their static function is similar to a dead-end tower . Anchor portals are almost always steel -tube or steel-framework constructions.
The frame synchronizer searches the incoming bit-stream for occurrences of the frame synchronization pattern. If the pattern persists for long enough that an accidental match is implausible, the synchronizer declares the data synchronized and available for decoding.
The 2,010-square-metre (21,600 sq ft), 34-metre-high (110 ft) vesica piscis-shaped building formed the frame with a glued-laminated timber beam and steel-rod skeleton covered with a glass skin. Considering the conventional mode of construction with steel or reinforced concrete moment-frame, this glulam-and-steel combination case is regarded as ...

Conventionally, it is a panel that fits into the doorway of a building, room, or vehicle. Doors are generally made of a material suited to the door's task.
