This chapter will present thebasic properties and requirements for bolts and welds. Connections are an intimate part of a steel structure and their propertreatment is essential for a safe and economic structure. An intuitiveknowledge of how a system will transmit loads the art of load paths ,and an understanding of structural mechanics the science of equilib-rium and limit states , are necessary to achieve connections which areboth safe and economic.

Chapter 2 will develop this material. The Aand A bolts are structural bolts and can be used for any buildingapplication. Twistoff-type tension control fasteners manufacturedunder ASTM F and F are also available and can be treated assubsets of A and A, respectively.

A bolts, which were referredto previously as common bolts, are also variously called machine bolts,ordinary bolts, and unfinished bolts. The use of these bolts is limited pri-marily to shear connections in nonfatigue applications. Structural bolts A and A can be installed pretensioned or snugtight.

Pretensioned means that the bolt is tightened until a tension forceapproximately equal to 70 percent of its minimum tensile strength isproduced in the bolt. Snug tight is the condition that exists when all pliesare in contact. It can be attained by a few impacts of an impact wrenchor the full effort of a man using an ordinary spud wrench. Common bolts A can be installed only to the snug-tight condition. There is no rec-ognized procedure for tightening these bolts beyond this point.

Pretensioned structural bolts must be used in certain locations. Section J1. Connections of all beams and girders to columns and any other beamsand girders on which the bracing of columns is dependent in struc-tures more than ft 38 m in height. In all structures carrying cranes of more than 5-ton 50 kN capac-ity: roof truss splices and connections of trusses to columns, columnsplices, column bracing, knee braces, and crane supports.

Connections for the support of machinery and other live loads thatproduce impact or reversal of load. In all other cases, A bolts and snug-tight A and A bolts can be used. This document, which is specific to A and A bolts,contains all of the information on design, installation, inspection, washeruse, compatible nuts, etc.

There is no comparable docu-ment for A bolts. The RCSC bolt spec. Many sizes of high-strength bolts are available, as shown in Table 1.

In general, a connection with a few large-diameter fasteners costs less thanone of the same capacity with many small-diameter fasteners. The fewerthe fasteners the fewer the number of holes to be formed and the lessinstallation work. Larger-diameter fasteners are generally favorable in con-nections, because the load capacity of a fastener varies with the square ofthe fastener diameter.

For practical reasons, however, and in-diameterfasteners are usually preferred. Shop and erection equipment is generallyset up for these sizes, and workers are familiar with them.

It is also advis-able to limit the diameter of bolts that must be pretensioned to in sincethis is the largest diameter tension control TC bolt available. Additionally, an ASTM F washer must be providedto cover the hole when a slotted hole occurs in an outer ply. Alternativelya in common plate washer can be used to cover the hole.

For other locations, snug-tight bolts should beused because they are cheaper with no reduction in strength. The vastmajority of shear connections in buildings can be snug tight, and shearconnections are the predominate connection in every building. Also, ifcommon bolts provide the required strength, they should be usedbecause they are less expensive than structural bolts. There is no dangerof interchanging the two types because all bolts are required to haveclear identifying marks, see Fig.

In bearing-type connections, boltthreads may be included in or excluded from the shear plane. Differentdesign strengths are used for each condition. Also, bearing-type connec-tions may be either pretensioned or snug-tight, subject to the limita-tions already discussed.

Snug-tight bolts are much more economical toinstall and should be used where permitted. The slip-critical connectionis the most expensive, because it requires that the faying surfaces be freeof paint, grease, and oil, or that a special paint be used.

Hence this typeof connection should be used only where required by the governing designspecification, for example, w. Post on Oct 1. Category: Documents 48 download.
