Experimental Investigation Of Steel Pipe Pile To Concrete Cap Connections, Ryan S. Eastman
Experimental Investigation Of Steel Pipe Pile To Concrete Cap Connections, Ryan S. Eastman
Theses and Dissertations
Piles are often used to resist vertical and lateral loads when shallow foundations are inadequate or uneconomical. A critical part in designing pile foundations is the pile-to-cap connection. When a moment resisting connection is desired, reinforcement is typically used between the pile and the cap. A pile-to-cap connection with sufficient pile embedment depth, however, may provide similar results. One model that is currently used to determine the capacity of a pile-to-cap connection was developed by Marcakis and Mitchell for steel members embedded in concrete. This model considers an embedment mechanism that resists rotation at the connection. Recent testing has shown, …

The use of embedded pile elements provides a convenient approach that may save significant modelling time in the simulation of piled foundations. A back-analysis of an Osterberg-cell (O-Cell) load test on a 45 m long pile is presented to illustrate some of the advantages of using structural embedded elements. Comparisons with other modelling approaches for piled-raft foundations have showed good agreement. Three dimensional effects on shaft friction were also investigated in this paper. The simplified example indicates that, although the ultimate shaft friction developed along piles within a piled raft can be significantly greater than that for a single pile …
