    This paper presents the results of field lateral load tests made on four instrumented timber piles in Morgan City, La. The test piles were instrumented, calibrated, driven, and tested under lateral loads during February and March 1966 at two sites adjacent to the Morgan City floodwall. Each test pile was instrumented with nine pairs of electrical SR-4 strain gages. The two test piles at each site were tested simultaneously by jacking the piles apart. Cyclic and repetitive load tests were made on the test piles. The following conclusions were made from the results of these tests and comparison of measured moments and pile head slopes with those computed based on the theoretical expressions: (1) timber piles are capable of supporting lateral loads, (2) the behavior of, and stresses in, timber piles under lateral loads can be evaluated using the theoretical solutions presently available, and (3) repeated loading causes an increase in the pile head deflection at a given load level. The ratio of the deflection after repeated loading to that of the first cycle loading increases with the increase in applied repetitive load.
