Shaft Capacity Of Continuous Flight Auger Piles In Sand, Kenneth Gavin, David Cadogan, Patrick Casey Feb 2009

Shaft Capacity Of Continuous Flight Auger Piles In Sand, Kenneth Gavin, David Cadogan, Patrick Casey

Publications

This paper presents the results of a series of field experiments performed to study the development of shaft resistance on continuous flight auger piles installed in sand. The test piles were instrumented in order to separate the shaft and base resistance, and to allow the determination of the distribution of shaft resistance along the pile shaft. The tests highlighted the importance of accurate calculation of the shaft resistance for nondisplacement piles. At a typical maximum allowable pile head settlement of 25mm, more than 71% of the pile resistance was provided by shaft friction. Conventional methods of estimating shaft resistance were …

Structural Behaviour And Analysis Of A Steel-Concrete Balcony Bracket, Sean Carroll

Theses

For commonly used moment connections, such as the various types of beam to column endplates, a large amount of information in relation to testing data and suggested design methods exist. Engineers can use this information to safely design such connections. When developing new and unique types of connections however, usually no prior testing information is available to engineers due to the unique design. At the present time, the most effective method of designing and developing any structural element or connection is through testing. Testing and detailed analysis of the results gives factual information on the behaviour of the structure, which …
