<p>Cyclic1D is a nonlinear Finite Element program for one-dimensional (1D) lateral dynamic site-response simulations. The program operates in the time domain, allowing for linear (Hughes 1987) and nonlinear studies. Nonlinearity is simulated by incremental ...

<p>Soil-structure interaction may play a major role in the seismic response of a bridge structure. Specifically, soil layers of low stiffness and strength may result in permanent displacement of the abutments and foundations, thus imposing important kinematic ...

During a Tunnel Boring Machine (TBM) project in Kunming city, Southwestern China the engineering geological conditions encountered at a distance of 7km consisted of folded, faulted, weak rocks, high ground stress and groundwater problems. The problems of collapse, ...

<p>In this paper, a single pile embedded in mildly inclined, liquefiable soil deposit is analyzed under dynamic base shaking conditions.</p>

<p>A series of four dynamic centrifuge model tests was performed to investigate the effect of foundation densification on the seismic performance of a zoned earth dam with a saturated sand foundation. In these experiments, thickness of the densified foundation ...

<p>This paper presents the application of the PEER (Pacific Earthquake Engineering Research) PBEE (Performance-based earthquake engineering) methodology to one of the six PEER testbeds, namely the Humboldt Bay Middle Channel (HBMC) Bridge, one of three bridges ...

A series of centrifuge model tests were conducted at Rensselaer Polytechnic Institute to study the seismic response of a caisson-type waterfront quay wall system, and the liquefaction and deformation characteristics of the saturated cohesionless backfill. ...

A mechanism of sand boil development during liquefaction is briefly discussed. In particular, the impact of sand boils as potential excess pore-pressure relief mechanisms is investigated within a computational solid-fluid fully coupled effective-stress framework ...

<p>During liquefaction, a shear-induced dilatancy mechanism may be one of the major factors that dictate soil behavior. As shear strain accumulates, this dilative tendency results in instants of excess pore pressure drop, sharp acceleration spikes, and associated ...
