geometrical profile (roughness) of joint surfaces influences the behaviour of rock joints under shear loading. with regard to the dilation, there are two models of direct shear test that may simulate the original loading condition existing in the location from where the specimens have been sampled. the first model in which the normal load is constant (cnl) and the discontinuity is free to dilat...

When the foundations of structures under cyclic loading with amplitudes less than their permissible load, the concern exists often for the amount of uniform and non-uniform settlement of such structures. Storage tank foundations with numerous filling and discharging and railways ballast course under repeating transportation loads are examples of such conditions. This paper deals with the effect...

The goal of this study was to develop an understanding of the nature of wave loading on a wood-framed scale residential building model for a variety of building configurations and test conditions. Testing was performed on a 1/6th scale two-story wood-framed residential structure. The structure was impacted with waves and tested in both flooded and nonflooded conditions. The measured forces were...

Misalignment or unbalanced loading of machine tool spindle bearings often results in skewed bearing operation, which makes the more susceptible to failure. In addition, due weak impact signal a single feature information cannot accurately characterize operation status bearing. To address above problems, this paper proposes method monitor uneven running state load based on dual-channel fusion im...
