<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, ...
Reference: IAEG2006 Paper number 717
<p>In this paper a multi-surface plasticity model for cohesionless granular materials is developed, in which theLade-Duncan failure criterion is employed as the yield function.</p>
