Description: | Miscellaneous Paper Abstract: A method is proposed to predict the response of piles in sand subjected to cyclic horizontal loading on the basis of cyclic pressuremeter tests. This method is an extension of the pressuremeter method proposed for piles subjected to monotonic horizontal loading. The pressuremeter-derived monotonic P-y curve is reduced by a multiplier N⁻ª to obtain the cyclic PN⁻ª- y curve. The parameter a is obtained readily from cyclic pressuremeter tests. This pressuremeter method was used to predict the response of a 10.75-in.-diam pipe pile embedded in 9.5 ft of sand and subjected to two-way cyclic horizontal loads with full reversal of loading. This pressurernet er method was also used to predict the response of 12 model pile tests in sand subjected to one-way and two-way cyclic horizontal loads. In addition, a data base of full-scale cyclic horizontal load tests was analyzed. The results show that (A.) two-way cyclic horizontal loading of piles in sand leads to minimal if not negligible degradation, (B.) one-way cyclic horizontal loading of piles in sand leads to significant degradation, (C.) the proposed method predicts with very good accuracy the degradation of piles in sand subjected to one-way cyclic horizontal loads, and (D.) the proposed method cannot predict the degradation (or lack of it) of piles in sand subjected to two-way cyclic horizontal loads because the pressuremeter is a one-way cyclic test.
