Influence of some rigidity-increased structures to the seismic stability of the concrete buttress dams

Abstract

    The buttress dams or abutment walls are slender structures in the line of damsite, so their ability to work under load, especially under seismic load in this direction is less effective than other directions. Therefore, the rigidity increasing of buttress dams in the line of damsite significantly improves their seismic resistance. This paper includes the analysis of the influence of some rigidityincreased structures like beams, arches, to the seismic stability of the concrete buttress dams.
