...-tensioned cross-laminated timber rocking walls. A suite of 22 far-field ground motions were used for nonlinear time history (NLTH) analysis. Truncated incremental dynamic analysis was used to scale the ground motions, and results of the NLTH analyses were used to develop cumulative distribution functions...

... the earthquake. Field surveys revealed that the coseismic surface ruptures were characterized by left-lateral offset, en echelon tensional cracks, mole tracks within a narrow zone, and large areas of sand liquefaction that increased the damage and losses. We measured the coseismic displacements along surface...

... source pressure ( P o ) to drive host-rock failure, but without tectonic stress. Here we present axisymmetric finite-element simulations of radially propagating sills for a range of tectonic stress (σ r ) conditions, from horizontal tension (σ r < 0) to horizontal compression (0 < σ r ). Response...

...) are well-documented phenomena. In shallow reservoirs such as in the Champion East field in offshore Brunei Darussalam ( van Kessel, 2002 ) and the Duri field in Indonesia ( Waite et al., 1997 ), faults are affected by very small differential stresses or are even in a tensional stress state. These stress...
