Culverts can be constructed of a variety of materials including cast-in-place or precast concrete (reinforced or non-reinforced), galvanized steel, aluminum, or plastic (typically high-density polyethylene). Two or more materials may be combined to form composite structures. For example, open-bottom corrugated steel structures are often built ...
Designed by Sir Edwin Airey to the Ministry of Works Emergency Factory Made housing programme, it features a frame of prefabricated concrete columns reinforced with tubing recycled from the canvas tilt frames of military trucks. A series of shiplap style concrete panels, tied back to the columns, form the external envelope. [1]
The precast concrete slab has tubular voids extending the full length of the slab, typically with a diameter equal to the 2/3–3/4 the thickness of the slab. This makes the slab much lighter than a massive solid concrete floor slab of equal thickness or strength. The reduced weight also lowers material and transportation costs.
A box girder bridge, or box section bridge, is a bridge in which the main beams comprise girders in the shape of a hollow box. The box girder normally comprises prestressed concrete, structural steel, or a composite of steel and reinforced concrete. The box is typically rectangular or trapezoidal in cross-section.
Tekla Structures is used in the construction industry for steel and concrete detailing, precast and cast in-situ. The software enables users to create and manage 3D structural models in concrete or steel, and guides them through the process from concept to fabrication. [8] The process of shop drawing creation is automated. It is available in ...
The design was produced in Scotland by the Orlit Company, resulting in most houses being located in Scotland and Ulster. On-site construction was based on a foundation which supported storey-high precast concrete columns at fixed intervals, supporting concrete beams fixed to the columns, resulting in a virtually monolithic frame.
Panelized homes (also referred to as system built homes), construct the structural components, or "panels", of a home (walls, roof and floor systems) in an off site factory where the panels are cut via automated saws and laser cutters from large wooden sheets, allowing for lower amount of waste compared to site-built construction.
