The techniques of passive HVSR seismic are aimed to define the mechanical properties

The techniques of passive seismic HVSR are aimed to define the mechanical properties of the subsoil starting from measurements of the field of environmental vibrations generated from uncontrolled sources of different kinds. The environmental noise has by nature an irregular trend. Passive seismic methods are based on the observation of a wave field physically linked…

Bearing capacity check for shallow foundations (SLU)

The vertical bearing capacity of the foundation soil is verified according to the theory of limit states using the following inequality: σ ≤ Rd/γRV or based on the factor of safety as: Rd/σ ≥ SFv where: σ-extreme design contact stress at the footing bottom Rd-design bearing capacity of foundation soil γRV-coefficient of vertical bearing capacity…

Ultimate Bearing Capacity of Footings Resting on Stratified Deposits of Soil, Meyerhof and Hanna 1978

Meyerhof Hanna 1978: Ultimate Bearing Capacity of Footings Resting on Stratified Deposits of Soil: All the theoretical analysis dealt with so far is based on the assumption that the subsoil is isotropic and homogeneous to a considerable depth. In nature, soil is generally non-homogeneous with mixtures of sand, silt and clay in different proportions. In…
