These include consideration of (1) Effects of earthquake input mechanism and radiation damping due to infinite canyon; (2) Effects of nonlinearity of contraction joint opening; (3) Effects of damage and fracture behaviors in dams and strengthening; (4) Effects of dam-reservoir interaction; (5) Earthquake stability of arch dam-abutment system. Procedures for considering the above factors are outlined. In Part II, engineering applications to high arch dams with a case study on the Dagangshan Arch Dam to resist the design earthquake are demonstrated and some concluding remarks are given.
