[ 1 ] : 25 The tendons are not placed in direct contact with the concrete, but are encapsulated within a protective sleeve or duct which is either cast into the concrete structure or placed ...
The last are used in concrete-steel composite structures as shear connectors. [6] Other uses include anchoring machines to poured concrete floors [ 7 ] and buildings to their concrete foundations. Various typically disposable aids, mainly of plastic, are produced to secure and align cast-in-place anchors prior to concrete placement.
There are three main non-wood pole materials and structures on which the attachment hardware may be mounted: concrete, steel, and fiber-reinforced composite (FRC). Each material has intrinsic characteristics that need to be considered during the design and manufacture of the attachment hardware. Concrete poles; Several power poles made of concrete
Dragon – (rare) A corner post supporting a dragon beam in jetty framing. Gunstock, jowled, flared, teasel (rare) – A flared post, larger at the top than the bottom, most commonly found in the side walls but could be any location. Rarely a post may have an "integral bracket" [14] which is a mid-post
Unlike an I-beam, a T-beam lacks a bottom flange, which carries savings in terms of materials, but at the loss of resistance to tensile forces. [5] T- beam designs come in many sizes, lengths and widths to suit where they are to be used (eg highway bridge, underground parking garage) and how they have to resist the tension, compression and shear stresses associated with beam bending in their ...
Wood components, Long says, are "literally the worst possible product you could use" in the event of high winds, flooding, or fire since they burn (unlike concrete) and aren't as sturdy as, say ...
