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.
EN 1993-3-2 applies to the structural design of vertical steel chimneys of circular or conical section. It covers chimneys that are cantilevered, supported at intermediate levels or guyed. It is concerned only with the requirement for resistance (strength, stability and fatigue) of steel chimneys.
In the case of steel products such as sections, bolts and fabricated steelwork the CE Marking demonstrates that the product complies with the relevant harmonized standard. [7] For steel structures the main harmonized standards are: Steel sections and plate – EN 10025-1; Hollow sections – EN 10219-1 and EN 10210-1; Pre-loadable bolts – EN ...
In solid mechanics and structural engineering, section modulus is a geometric property of a given cross-section used in the design of beams or flexural members. Other geometric properties used in design include: area for tension and shear, radius of gyration for compression, and second moment of area and polar second moment of area for stiffness .
In the United Kingdom, these steel sections are commonly specified with a code consisting of the major dimension, usually the depth, -x-the minor dimension-x-the mass per metre-ending with the section type, all measurements being metric. Therefore, a 152x152x23UC would be a column section (UC = universal column) of approximately 152 mm (6.0 in ...

The connecting face of the flange is either square, circular or (particularly for large [1] or reduced-height rectangular waveguides), rectangular. The connection between a pair of flanges is usually made with four or more bolts , though alternative mechanisms, such as a threaded collar, may be used where there is a need for rapid assembly and ...
