Influences of Cross Section Parameters on Bending Resistance of TSC Pile

Abstract:

Precast thin-wall steel and spun concrete composite pile (TSC pile) is a kind of new type of steel-concrete composite pile whose bearing performance is between steel pile and concrete pile. This article adopted FEM software to set up 3D TSC pile model to analyze its performance. Through the comparison with actual pure bending bearing experiment results, the model’s reliability was verified and the results showed that the model was reliable. Then lots of bending bearing capacity contrast calculations were conducted by using different cross section parameters (outside diameter, concrete pipe’s wall thickness and steel pipe’s wall thickness), and the influences of these parameters on bending resistance of TSC pile were discussed. The results showed that: with the increase of outside diameter, concrete pipe’s wall thickness and steel pipe’s wall thickness, TSC pile’s ultimate flexural bearing capacity increased. The influences of different parameters were not the same, outside diameter was the most important parameter, then concrete pipe’s wall thickness, and the last one was steel pipe’s wall thickness.
