2) Cyclic Loading - Refer to Beard (1980) for details 

 of cyclic capacity prediction scheme developed by 

 Herrmann (1980). 



- Caused by wave induced forces and cable strumming. 



Cyclic loads < 5% static capacity of no concern, 

 therefore, cable strumming can be ignored. 



Cyclically loaded anchors designed to preclude failure 

 from liquefaction or cyclic creep. 



Characterized by 

 strength loss and 

 sudden anchor 

 instability 



Accumulation of 

 small movements 

 that reduce anchor 

 depth until pull 

 out occurs. 



Strength Loss During Cyclic Loading 



The following procedure excludes soils such as uniform fine 

 sand, coarse silts, and some clean oozes which are susceptible to 

 true liquefaction failure. Use of plate anchors in these soils 

 under cyclic loading is not recommended at this time.
