A hollow structural section (HSS) is a type of metal profile with a hollow cross section. The term is used predominantly in the United States, or other countries which follow US construction or engineering terminology. HSS members can be circular, square, or rectangular sections, although other shapes such as elliptical are also available.
Plate, metal sheets thicker than 6 mm or 1 ⁄ 4 in. Open web steel joist; While many sections are made by hot or cold rolling, others are made by welding together flat or bent plates (for example, the largest circular hollow sections are made from flat plate bent into a circle and seam-welded). [2]
The bending rigidity and strength of the frame members is therefore the primary source of lateral stiffness and strength for the entire frame. [1] The 1994 Northridge earthquake revealed a common flaw in steel-frame construction — poorly welded moment connections — and building codes were revised to strengthen them. [2]
Metal fabrication is the creation of metal structures by cutting, bending and assembling processes. It is a value-added [1] process involving the creation of machines, parts, and structures from various raw materials. Typically, a fabrication shop bids on a job, usually based on engineering drawings, and if awarded the contract, builds the ...
It displays videos on two LED screens, each encapsulated in a glass brick tower measuring 50 by 23 by 16 feet (15.2 by 7.0 by 4.9 m). [1] The firm designed a special stainless steel T-frame both to bear the load of the walls, which are 50 feet (15 m) high, and to withstand lateral wind forces. The frame holds all the glass blocks and transfers ...
