	Buttress dams were constructed mainly in early 20th century when labor was cheap and materials were expensive. Buttress dams reduced the concrete required to build a typical gravity dam by as much as 60 percent. For [[stability]], these relatively light structures required upstream sloping water barriers resulting in the water force acting downward. These structures were designed to carry load in ~~stream~~ direction, but typically did not consider [[seismic]] or other loadings in the cross-stream direction and are therefore vulnerable to these conditions.<ref name="Buttress">[https://www.usbr.gov/ssle/damsafety/risk/BestPractices/Presentations/E5-ButtressDamsPP.pdf Buttress Dams (United States Bureau of Reclamation, 2019)]</ref>		[[Buttress Dams\|Buttress dams]] were constructed mainly in early 20th century when labor was cheap and materials were expensive.

	Finite element analyses of an entire buttress structure is needed to understand the [[structural]] response. Cracking or yielding of reinforced concrete members does not necessarily equal dam failure for buttress-type structures.<ref name="Buttress"/>		Finite element analyses of an entire buttress structure is needed to understand the [[structural]] response.
