On Earthquake Ground Motion and Structural Response in Alluvial Valleys

  title={On Earthquake Ground Motion and Structural Response in Alluvial Valleys},
  author={Jacobo Bielak and Jifeng Xu and Omar Ghattas},
This paper is concerned with the problem of soil ampli cation and structural damage due to local site conditions in sedimentary valleys during earthquakes. It focuses on a small valley in Kirovakan, for which one dimensional (1D) wave propagation analyses have failed to provide adequate answers for the large extent and spatial distribution of damage during the 1988 Armenia Earthquake. A more realistic two-dimensional nite element analysis is performed herein in search of an explanation for the… CONTINUE READING
