  2. Precast concrete lifting anchor system - Wikipedia

    en.wikipedia.org/wiki/Precast_concrete_lifting...

    and assuming the test data is taken from a statistically valid test method, the data is to be determined via statistical means to derive the Load resistance model, for the anchor. There are adequate load case coefficients available to estimate sling angle load amplification , suction from the casting bed , and various dynamic transportation ...

  5. Flexural modulus - Wikipedia

    en.wikipedia.org/wiki/Flexural_modulus

    For a 3-point test of a rectangular beam behaving as an isotropic linear material, where w and h are the width and height of the beam, I is the second moment of area of the beam's cross-section, L is the distance between the two outer supports, and d is the deflection due to the load F applied at the middle of the beam, the flexural modulus: [1]

  6. Lifting beam - Wikipedia

    en.wikipedia.org/wiki/Lifting_beam

    The lifting beam (also known as traverse, spreader beam) is a steel beam that is attached to the hook of the crane in order to spread the slings from one end of an elongated load (like a wall panel) to another. The bottom of the beam has multiple connection points for hanging the load. [1] H-shaped traverse. The lifting beams are used in ...

  7. Concrete slump test - Wikipedia

    en.wikipedia.org/wiki/Concrete_slump_test

    The ASTM standards also regulate the rigidity of the cone. It states in the procedure that when the cone is removed, it should be lifted up vertically, without any rotational movement at all. [6] The concrete slump test is known as "Standard Test Method for Slump of Hydraulic-Cement Concrete" and carries the code (ASTM C 143) or (AASHTO T 119).

  8. Static load testing - Wikipedia

    en.wikipedia.org/wiki/Static_load_testing

    Kentledge load testing in Haikou, Hainan, China. 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.

  9. Airy points - Wikipedia

    en.wikipedia.org/wiki/Airy_points

    A beam supported at its Airy points has parallel ends. Vertical and angular deflection of a beam supported at its Airy points. Supporting a uniform beam at the Airy points produces zero angular deflection of the ends. [2] [3] The Airy points are symmetrically arranged around the centre of the length standard and are separated by a distance equal to
