  • Bearing Capacity Assessment Method - Independent

    2013-10-29 · In Christchurch here there is a method/guidance paper that is used to assess the bearing capacity for small structures. Its called the Stockwell Method. Attached is a copy of the paper. In summary, its based off Scala Penetrometer blows per 150mm which is plotted on a graph that gives an allowable bearing capacity.

  • Bearing capacity analysis using the method of ...

    2013-4-1 · Using the method of characteristics, the bearing capacity for a strip footing is analyzed. The method of characteristics leads to an exact true limit load when the calculations of the three terms in the bearing capacity formula are consistent with one collapse mechanism and the soil satisfies the associated flow rule. At the same time, the method of characteristics avoids the assumption of ...

  • OPTIMISATION OF BEARING DIAGNOSTIC

    2000-9-1 · Abstract. In this paper, bearing fault vibrations are modelled as a series of impulse responses of a single-degree-of-freedom system. The model incorporates slight random variations in the time between pulses so as to resemble actual vibration signals. Although the bearing fault harmonics in the raw spectrum are caused by the random fluctuations to ...

  • Curvature enhanced bearing fault diagnosis method

    2020-5-30 · As a novel representation method, two dimensional (2D) segmentation is gaining ground as an effective condition monitoring method due to its high-level information descriptional ability. However, the accuracy of extracting frequency information is still limited by the finite gray-level and the extraction ability of distinguishable texture for each fault.
