Tag: Shear Punching shear

Where a thin composite slab has to be designed to resist point lads (e.g. from a steel wheel of a loaded trolley), resistance to punching shear may be critical. Failure is assumed to occur on a ‘critical perimeter’, of length Cp, which is defined as for reinforced concrete slabs. For a loaded area ap by bp, remote from a free edge, and 45°spread

Tag: Shear The m-k or shear-bond test

The effectiveness of shear connection is studied by means of loading tests on simply by means of loading tests on simply-supported composite slabs, as sketched in Fig 2.19 Specifications for such tests are given in Section 10.3 of Eurocode4 and in BS 5950:Part 4.(27) The length of each shear span, Ls is usually L/4,where L is the span ,which is

Tag: Shear Properties of shear connectors

The property of shear connector most relevant to design is the relation-ship between the shear force transmitted, P, and the slip at the interface, s This load-slip curve should ideally be found from tests on composite beams, but in practice a simpler specimen is necessary Most of the data on connectors have been obtained from various types of push-out or

Tag: Shear Methods of analysis and design

The purpose of this section is to provide a preview of the principal methods of analysis used in this volume, and to show that most of them are straightforward applications of methods in common use for steel or for concrete structures. The steel designer will be familiar with the elementary elastic theory of bending, and the simple plastic theory in which the

Tag: Shear Bearing-Type Bolted Connections

When some slip, although very small, may occur between connected parts, the  fasteners are assumed to function in shear. The presence of paint on contact surfaces is therefore of no consequence. Fasteners may be A307 bolts or high-strength bolts or any other similar fastener not dependent on development of friction on the contact surfaces. Single shear occurs when opposing forces act on a

Tag: Shear Criteria for Composite Construction

In composite construction, a steel beam and a concrete slab act together to resist bending. The slab, in effect, serves as a cover plate and allows use of a lighter steel section. The AISC ASD and LRFD specifications for structural steel buildings treat two cases of composite members: (1) totally encased members that depend on the natural bond between the

Tag: Shear Combined Tension and Shear

Combined tension and shear stresses are of concern principally for fasteners, plate-girder webs, and ends of coped beams, gusset plates, and similar locations. Tension and Shear in Bolts The AISC ‘‘Load and Resistance Factor Design (LRFD) Specification for Structural Steel Buildings’’ contains interaction formulas for design of bolts subject to combined tension and shear in bearing-type connections. The specification stipulates that the tension

Tag: Shear Bracket Connections

Brackets are projections that carry loads. The connection of a bracket to a support has to transmit both shear and moment. Fasteners or welds may be used for the purpose. Connections may be made with fasteners or welds subjected only to shear or to combined shear and tension. Figure 5.46 shows a plate bracket connected with bolts in single shear.
