Design charts for seismic pressures against rigid walls subjected to horizontal earthquake shaking are presented for both uniform and nonuniform backfills. Solutions are based on a simplified model of soil response which gives results that agree almost exactly with rigorous solutions. Peak seismic thrusts are presented for three different soil profiles. For each profile, 250 combinations of gro...

A performance-based seismic design (PBSD) method is aimed at controlling the structural damage based on precise estimations of proper response parameters. PBSD method evaluates the performance of a building frame for any seismic hazard, the building may experience. Use of this method for vertical irregular building is verified with comparison of conventional method. Vertical irregular frame is ...

In seismic interferometry the response to a virtual source is created from responses to sequential transient or simultaneous noise sources. Most methods use crosscorrelation, but recently seismic interferometry by multidimensional deconvolution (MDD) has been proposed as well. In the simultaneous-source method (also known as blended acquisition), overlapping responses to sources with small time...
