Behaviour of earth dams during earthquakes
Dynamic stresses and displacements in dams due to horizontal and vertical components of earthquake accelerations are determined; effects of various foundation conditions on magnitudes of dynamic stresses are evaluated; among other things, studies show danger of cracking of dams on relatively soft foundations under earthquake loading (cracks initiating at base of dam) and importance of ratio of fundamental period of dam to that of earthquake acceleration record; it is clear that specifying design earthquake involves specifying both suitable magnitude and frequency; incorporation of dynamic results in seismic design is discussed.
