Static Load Testing of Driven Piles

As a continuing service to our clients, Atlas Tube routinely enlists the services of industry leaders in matters related to driven pipe piles. This is the sixth in a series of topics provided at our request by Wagner Komurka Geotechnical Group, Inc.

Driven pile test programs may include static load testing, which involves incrementally loading a pile while measuring (at a minimum) pile deflection. Static loads may be applied in axial compression (from the top down, or from the bottom up), in axial tension, or laterally. The most-common type of static load test is top-down axial compression. It is worth emphasizing that the main objective of static testing is to characterize soil behavior. In pile design, this is where the majority of uncertainty exists, as pile behavior can be predicted reasonable well. Static compression and tension load test piles may be instrumented to obtain load-transfer information (i.e., shaft resistance distribution) to correlate with static analyses and/or dynamic testing results, characterize set-up, estimate shaft resistance in scour, down force, or liquefiable zones, etc. Static lateral load test piles may be instrumented to obtain deflected-shape information to aid in refining lateral pile design software input parameters.

9 Interesting Facts about U.S. Infrastructure Spending

Public Spending on Transportation and Water Infrastructure 2014
Public Spending on Transportation and Water Infrastructure by category 2014
Fed Govt and State and Local govt shares of spending on infrastructure by category 2014
Federal Spending Infrastructure 2014

As 2015 comes to an end, we wanted to take some time to look at an area that has a significant impact on our pipe piles product division: infrastructure spending. An option for deep foundation support, our ERW straight seam pipe piling products have been used throughout the country in various infrastructure projects, including bridges and structures, as well as other DOT and US Army Corps of Engineers’ projects (if you’d like additional information about these projects, please contact us).

Dynamic Testing of Driven Piles

Dynamic Pile Testing
As a continuing service to our clients, Atlas Tube routinely enlists the services of industry leaders in matters related to driven pipe piles. This is the fourth in a series of topics provided at our request by Wagner Komurka Geotechnical Group, Inc.

Dynamic testing of driven piles is a valuable, cost-effective tool for the design and construction control of foundation projects which utilize driven piling. Testing is performed during the pile driving process, and consists of attaching strain gages and accelerometers to a pile near its head. The instrumentation system continuously records measured strains and accelerations in a pile, which are induced downward in the pile by high-strain impacts from each hammer blow, and are reflected upward in the pile by soil or rock resistance, or changes in pile impedance (changes in cross-section, or from the pile toe). The data collected by dynamic testing can be viewed in real time during driving, and for each hammer blow can provide such information as:

Seattle Transfer Station

On Tuesday, September 22, 2015, Atlas Tube participated in kicking off SteelDay from the Emerald City – Seattle, Washington. The focus of the event was the active construction site for the Seattle North Transfer station, a public works project for processing and transferring municipal solid waste (MSW), organic materials, and recyclables. Featuring 90 tons of ASTM A1085 hollow structural sections (HSS) for the long span roof trusses, the North Transfer Station is the largest ASTM A1085 project to date on the West Coast.
