The tension failure loads predicted by the CCD method fits experimental results over a wide range of embedment depth (e.g. 100 – 600 mm). [2] Anchor load bearing capacity provided by ACI 349 does not consider size effect, thus an underestimated value for the load-carrying capacity is obtained for large embedment depths.
where the first term represents the load carried by the concrete and the second term represents the load carried by the steel. Because the yield strength of steel is an order of magnitude larger than that of concrete, a small addition of steel will greatly increase the strength of the column. [1]
Anchor capacity, or load resistance, should be considered for tensile loads (axial), sling angle (angular) and shear loads (transverse). Consideration of different load combinations may result in wide variations required from the lifting insert. The load directions during production, transport and placement should be considered carefully.
Static load testing is an in situ type of load testing used in geotechnical investigation to determine the bearing capacity of deep foundations prior to the construction of a building. It differs from the statnamic load test and dynamic load testing in that the pressure applied to the pile is slower.
Dynamic load testing (or dynamic loading) is a method to assess a pile's bearing capacity by applying a dynamic load to the pile head (a falling mass) while recording acceleration and strain on the pile head. Dynamic load testing is a high strain dynamic test which can be applied after pile installation for concrete piles. For steel or timber ...
In structural and mechanical engineering, the shear strength of a component is important for designing the dimensions and materials to be used for the manufacture or construction of the component (e.g. beams, plates, or bolts). In a reinforced concrete beam, the main purpose of reinforcing bar (rebar) stirrups is to increase the shear strength.
The aim of plate theory is to calculate the deformation and stresses in a plate subjected to loads. Of the numerous plate theories that have been developed since the late 19th century, two are widely accepted and used in engineering. These are the Kirchhoff–Love theory of plates (classical plate theory)
A crane's rated load is its Safe Working Load (SWL) and the design load (DL) is, (p 90) [1] = The dynamic lift factor for offshore cranes in the range 10 kN < SWL ≤ 2500 kN is not less than =.(p 84) [1] Thus for a crane with a SWL of 2000 kN (~200 tonne) its design load is not less than, = = The minimum breaking load (MBL) for the combined capacity of reeves of a steel wire hoisting rope ...
