Tag: Welded Development, Anchorage, and Splices of Reinforcement

Steel reinforcement must be bonded to the concrete sufficiently so that the steel will yield before it is freed from the concrete. Despite assumptions made in the past to the contrary, bond stress between concrete and reinforcing bars is not uniform over a given length, not directly related to the perimeter of the bars, not equal in tension and compression, and may be affected

Tag: Welded Eccentrically Loaded Welded Connections

Welds are of two general types, fillet (Fig. 7.43a) and groove (Fig. 7.43b), with allowable stresses dependent on grade of weld and base steels. Since all forces on a fillet weld are resisted as shear on the effective throat (Art. 7.31), the strength of connections resisting direct tension, compression and shear are easily computed on the basis that a kip of fillet shear resists

Tag: Welded Fasteners

Two basic types of fasteners are typically used in construction, bolts and welds. Both are used in the fabricating shop and on the job site in connections joining individual members. Welds are also used to fasten together components of built-up members. Bolts, however, are more commonly used for field connections, and welds, for shop work. Rivets, which were once widely used for main

Tag: Welded Copper

The excellent corrosion resistance of copper makes it suitable for such applications as roofing, flashing, cornices, gutters, downspouts, leaders, fly screens, and similar applications. For roofing and flashing, soft-annealed copper is employed, because it is ductile and can easily be bent into various shapes. For gutters, leaders, downspouts, and similar applications, cold-rolled hard copper is employed, because its greater hardness and stiffness permit it to

Tag: Welded Welded Connections

Various types of welds may be used to joint cold-formed steel members such as groove welds in butt joints, fillet welds, flare groove welds, arc spot welds, arc seam welds, and  resistance welds. The nominal strength, Pn, for several of these weld types is given in this article. More complete information may be found in the AISI Specification. The provisions given are applicable

Tag: Welded Compression Splices

The requirements for strength of splice given in Art. 5.26 for tension splices apply also to compression splices. Compression members may be spliced with complete-penetration groove welds. As for tension splices, with such welds, it is desirable that splice plates not be used. Groove-welded compression splices may be designed for the basic allowable stresses for base metal. Fatigue does not control if

Tag: Welded Welded Studs

Fasteners with one end welded to a steel member frequently are used for connecting material. Shear connectors in composite construction are a common application. Welded studs also are used as anchors to attach wood, masonry, or concrete to steel. Types of studs and welding guns vary with manufacturers. Table 5.3 lists approximate allowable loads for Allowable Stress Design for several

Tag: Welded Welded Splices in Heavy Sections

Shrinkage during solidification of large welds in structural steel members causes, in adjacent restrained metal, strains that can exceed the yield-point strain. In thick material, triaxial stresses may develop because there is restraint in the thickness direction as well as in planar directions. Such conditions inhibit the ability of a steel to act in a ductile manner and increase the possibility of brittle fracture.
