TL;DR: In this article, a load-displacement relationship for single piles subjected to lateral load, embedded in sands, considering soil nonlinearity using subgrade reaction was developed to predict the load displacement relationship.
Abstract: A method has been developed to predict the load-displacement relationship for single piles subjected to lateral load, embedded in sands, considering soil nonlinearity using subgrade reaction. This is the first systematic study to develop lateral load-deflection curves using modulus degradation with strain. Based on the analysis of 14 full-scale lateral pile-load tests, an empirical equation of modulus degradation with strain and a range of k hmax values, i.e., k h at 0.002 strain at 1 m (3.28 ft) depth, has also been proposed. An example problem is included to demonstrate its use. Based on this method, the computed load deflections have been compared with the observed ones and with those based on p - y analysis. This method shows promise over the p - y solutions and predicts upper- and lower-bound load-deflection curves, which are valuable guides to making informed engineering decisions.

TL;DR: In this article, a mechanical cantilever resonator with passive integrated optics for motion detection is presented. But the resonator acts as a waveguide, and enables optical detection of deflection/displacement amplitude, including oscillations.
Abstract: A substrate incorporates a mechanical cantilever resonator with passive integrated optics for motion detection. The resonator acts as a waveguide, and enables optical detection of deflection/displacement amplitude, including oscillations. In one embodiment, the cantilever comprises a silicon waveguide suspended over a substrate. A reflector structure faces a free end of the suspending cantilever, or a waveguide is supported facing the free end of the suspended cantilever to receive light transmitted through the silicon waveguide cantilever. Deflection/displacement of the cantilever results in modulation of the light received from its free end that is representative of the displacement. Ring resonators may be used to couple different wavelength light to the waveguides, allowing formation of an array of cantilevers.
