Abstract :
: In addition to the dynamic effects of faulting that cause earthquake wave propagation, large-scale deformation of faulting is a hazard for structures near the fault. Analytical and numerical studies have been conducted on fault rupture propagation through soil deposits and soilstructure interactions such as buried pipelines and buildings. However, evaluating the results is difficult because well-documented field case histories are limited. Researchers resort to physical modeling and laboratory tests to address this deficiency. Because full-scale modeling is time consuming and costly, centrifuge modeling is the best option. The first step for centrifuge modeling of faulting is to design and manufacture a fault simulator in a centrifuge. Inthispaper, allavailable information aboutfault simulatorsworldwideispresentedasanarchive forresearchers. Adetailedreport onthe design and manufacture of the new fault simulator at the Univ. of Tehran is also presented and the testing of a simulated buried continuous pipeline subjectedtonormalandreversesfaultingisdiscussed.Thefaultsimulatorresultswereshowntocorrespondtonaturalfaultingdeformation.
