Introduction
bull 16 m high earth dam is of class III (SFOE guidelines)
=gt Replacement forces analysis can be conducted
bull Global horiz acceleration log(ah) = 026 IMSK + 019 in cms2
bull IMSK from seismic intensity maps Treturn = 1rsquo000 years
bull Here ah = 165 cms2 = 017g
bull av = 23ah = 011g (both upwards and (here) downwards)
