Numerical assessment of the influences of uplift pressure in joints on the seismic response of an arch dam having a jointed foundation

Joints, which are usually located in the abutments of dams, play a vital role seismic stability evaluation arch dams. This paper presents comprehensive numerical investigation influence uplift pressure joints on response an dam, with focus interaction between dam and rock wedges. For this study, Bakhtiari having one wedge at each abutment, was chosen as case three distinct finite element models were developed. Three components El Centro applied to dam's foundation, influences dam-rock crest displacement time history tensile damage investigated. Four different scenarios taken into account. The results indicated that taking account has important effects responsesWedge;Arch dam.
