A flexural capacity test is presented of a long precast concrete sheetpile system, intended as a protection wall for a water storage canal bank in soft-ground conditions, for a nursing college in Penang, Malaysia. The precast concrete sheetpile with a length of 7 m and a maximum exposed corrugated-section height of 1.8 m, was designed at Ultimate Limit State (ULS) bending moment of 175 kNm. A total of 2 specimens of precast concrete sheetpiles were tested in the Heavy Structure Laboratory at School of Civil Engineering, Universiti Sains Malaysia. The test method specified in Malaysian Standard MS 1314 was adopted. The results showed that the capacity of Specimens 1 and 2 were respectively 1.49 and 1.48 times higher than the designed capacity at ULS. The test set-up, to reflect the practical behavior of precast concrete sheetpile, and the test procedures are also described.
