Flexural and shear rigidity of composite sheet piles
The flexural and shear rigidities of a pultruded fiberglass composite sheet pile panel were determined experimentally and analytically. The purpose of the experimental work was to simultaneously determine their flexural and shear rigidities of the sheet piling for deflection analysis of sheet pile wall. The Timoshenko's equation method was used to directly determine the rigidities. Independent results were obtained from three-point bending tests as well as four-point bending tests. The two values of the flexural rigidity determined from different test setups agreed very well with each other, indicating that the flexural rigidity so obtained was independent from the test span and setup, had no shear effect involved and as the largest possible value from bending tests. The multispan test method is suitable for being considered as a standard test method for flexural rigidity of composite sheet piling. However, the two shear rigidities varied significantly more than the flexural rigidity. This discrepancy was probably caused by the first order assumption used in Timoshenko beam theory. The flexural and shear rigidity of the composite sheet piling were also obtained analytically by programming the derived expressions in MS Visual Basic as a preliminary design tool.
