TL;DR: In this article, a simplified formulation for Levy plates composed of interlocking girders endowed with exact stiffness, geometric stiffness, and consistent mass matrices is presented for bending, buckling, and free vibration problems for rectangular Levy plates supported on elastic foundations.
Abstract: In many engineering problems the need for accurate and rapid computation of stresses and deformations in Levy plates on 2-parameter foundations is encountered. The challenge may be met in a simplified way by resorting to a finite grid model of intersecting beams on generalized elastic foundations. The simplified formulation in this article is based on the discretized representation for plates composed of interlocking girders endowed with exact stiffness, geometric stiffness, and consistent mass matrices. These have been obtained through the use of exact shape functions. Sample problems of bending, buckling, and free vibration problems for rectangular Levy plates supported on elastic foundations are solved. Comparisons with known analytical solutions and other numerical solutions are presented.

TL;DR: In this paper, the authors present the results of characterization physical, mechanical and hydro-mechanical behavior of silty soils in such training, in order to evaluate the possible causes of the movement.
Abstract: In April of 2014 arose a movement mass of soils which make up the terrace of the municipality of Olaya (Department of Antioquia). This document presents the results of characterization physical, mechanical and hydro-mechanical behavior of silty soils in such training, in order to evaluate the possible causes of the movement. Were confronted the hypothesis raised by the competent entities that once evaluated the problem and was determined from this research that the soil, for the conditions on the ground, experiences an apparent cohesion as a result of the generation of pore pressures negative, however, when the material comes in contact with water, this cohesion is lost quickly leads to the shear resistance of the material only depend on the angle of internal friction.
TL;DR: In this paper, a probe is designed to measure the in-place value of internal friction angle for cohesionless soils and the behavior of the probe is similar to that of a rough footing forced into the soil.
Abstract: A probe is designed to measure the in-place value of internal friction angle for cohesionless soils. The behavior of the blunt probe is similar to that of a rough footing forced into the soil. The face of the probe is split and capable of measuring shear forces which vary with the internal friction angle of the soil. A series of static penetration tests in dry sand show the variation of the ratio of shear and normal forces on the probe face (R/N) with soil friction angle φ.
