Towards the numerical simulation of seismic excitation [PDF]
Nuclear Engineering and Design, 2000 Recent advances in the numerical simulation of the rupture process in solids, namely mode I fracture propagation, are extended to account for sliding with friction along pre-existing fracture surfaces, with the final objective of analyzing seismic fault motions.

Nonstationary Random Critical Seismic Excitations [PDF]
Journal of Engineering Mechanics, 1987 A method is presented to find nonstationary random seismic excitations with a constraint on mean square value such that the response variance of a given linear system is maximized. It is also possible to incorporate the dominant input frequency into the analysis.

3D IDENTIFICATION OF BUILDINGS SEISMICALLY EXCITED
IFAC Proceedings Volumes, 2005 Abstract An algorithm to identify the parameters of a 3D model of a building subjected to two orthogonal components of seismic excitation is presented. A convenient reparameterization is proposed for a least-squares algorithm that allows an important reduction in the order of the covariance matrix, when compared with the standard formulation.
