Full size testing of sheet pile walls
conference paper
Azobé (Lophira alata) is widely used in timber sheet pile walls in the Netherlands. The boards in these walls are coupled and therefore load-sharing can be expected. A simulation model based on the finite element method DIANA (DIANA, 1992) was developed and load-sharing could be calculated. To check these simulations full size tests on single boards and on sheet pile walls containing five boards were performed. The test programme so far has shown that load-sharing exists and that the characteristic strength of the sheet pile walls tested is about 23% higher then the characteristic strength of the single boards. The simulation model predicted a load-sharing factor of 1.15 based on brittle material behaviour. Tests on single boards showed a more plastic behaviour. After completion of the tests and an adaption of the model other geometries will be calculated to see whether the load-sharing factor obtained from the tests is allo applicable for other gcometries and species.
