A Simplified Procedure for Base Sliding Evaluation of Concrete Gravity Dams under Seismic Action

Table 8

Existing dams: spectral acceleration given by the Italian Code for the different limit states (SLO, SLD, SLV, SLC) for granite.

Dam	Period (s)	Rock type	SLO 𝑎(𝑇) (m/s^2)	SLD 𝑎(𝑇) (m/s^2)	SLV 𝑎(𝑇) (m/s^2)	SLC 𝑎(𝑇) (m/s^2)
2	0.23	granite	1.9	2.31	5.22	6.46
3	0.3		1.07	1.5	4.72	6.12
4	0.33		1.53	2	5.4	7.3
