Fundamental Dynamics and Performance Assessment of Three-Dimensional Seismic Isolation
… response of a simplified model consisting of a rigid block resting on isolation bearings is studied. The overall structural response of the 3D isolated block is evaluated through drift ratio, vertical and horizontal displacement and acceleration amplification factors. A parametric study is …

The role of long-term tectonic deformation on present day seismicity in the Caribbean and Central America
… finite element grid that is comprised of block geometries defined from previous studies. Second, we isolate and remove anomalous signals that are inconsistent with rigid block motion from the latest open access community Global Navigation Satellite System (GNSS) velocity solution from …

Design of structurally-sound masonry buildings using 3D static analysis
… using a novel penalty formulation, assuming a rigid-block behavior of masonry. Two methods were developed that apply this model of feasibility to structural optimization. In the first approach, structural feasibility is introduced into procedural modeling of buildings. A set of designated free …

Impact of Jet Grouting on the Lateral Strength of Soil Surrounding Driven Pile Foundations
… of the jet-grout treated zones displaced as a rigid block. A majority of the increased lateral resistance came from the passive soil resistance acting on the face of the blocks and the adhesive soil resistance acting on the sides and bottom of the block as it displaced through the native soil. …

Morphology and structure of the accretionary prism offshore North Sumatra, Indonesia and offshore Kodiak Island, USA : a comparison to seek a link between prism formation and hazard potential
… common; for northern Sumatra, a seaward dipping rigid backstop may be the reason, which assists subsequent younger accreted sediment to form the observed zone. The prism toe region shows prominent mass failures presumably related to activation of thrust faults and/or the shaking in response to …

Dynamic identification of the Augusta hybrid base isolated building using data from full scale push and sudden release tests
… of the isolation system provided the mass of the rigid block, the bi-linear properties used in the mechanical representation of the rubber bearings and the sliding coefficient of friction for the Coulomb model used in the modelling of the sliders. The obtained parameters, showed that rubber …

The dynamic soil structure interaction of shallow foundations on dry sand beds
… and underlying soil. This results in a rigid coupling of the foundation with the soil and hence the full transmission of the seismic energy into the foundation. Consequently the structure located on the foundation either has to be isolated from the shaking through manufactured damping …

Macro-element nonlinear dynamic analysis for the assessment of the seismic vulnerability of masonry structures
… and simulating the rocking motion of a rigid block and the nonlinear hysteretic behaviour of masonry structures. After validation, this modelling approach was employed for the assessment of the out-of-plane behaviour of two unreinforced masonry structures previously tested by means of …

Analysis of the Stability and Response of Deep-Seated Landslides by Monitoring their Basal Temperature
… millions of cubic meters that move as a rigid block on top of a deep (below the roots of the trees and the groundwater level) basal layer of heavily deformed minerals. This kind of landslides geometrically shears as translational/rotational (depending on the stratigraphy of the area), …
