Statnamic pile load test is a Rapid Load Test method directly measuring applied pile loads and displacements which provides user-independent load test results. We conduct Statnamic load test in Singapore, Malaysia, Taiwan according to CP4 (Singapore), EN 22477-10 and ASTM-D7383 standards.
Developed jointly by Bermingham Foundation Solutions of Canada and TNO Building and Construction Research of the Netherlands, the STATNAMIC load test has been designed to meet the construction industry's demand for an accurate and cost-effective method of determining the load bearing capacity of caissons and high-capacity piles. The method is able to increase the overall productivity of the construction by shortening the time frame required for pile testing.
In STATNAMIC testing, solid fuel is burned within a pressure chamber. As the pressure increases, an upward force is exerted on a set of reaction masses while an equal and opposite force pushes downward on the pile. Loading is perfectly axial and the relatively slow application and release of compressive forces eliminates tensile stresses, compressing the pile and the soil as a single unit, allowing an accurate measurement of the load-displacement behavior.
The STATNAMIC load test can be utilized on almost any type of pile with little to no prior planning required and no reaction piles are required. Incredibly, several STATNAMIC load tests can be completed for the same cost as a single traditional static load test and multiple STATNAMIC load tests can be performed in a single shift.
Statnamic Testing for the Taipei Financial Center
In 1999 Diagnostic Engineering Consultants Ltd. (DECL) of Taipei undertook one of the most ambitious foundation load testing programs in Taiwan. The project was the high-profile Taipei Financial Center, planned as a 110-storey, 508m (1666ft) building the tallest in the world. Although the height of the building was later reduced, the foundations were designed and constructed based on the 110-storey proposal.
The foundation of this massive building was comprised of 546 large-diameter bored piles installed by the Reverse Circulation Drilling Method. Pile lengths varied from 62m (203ft) to 80m (262ft), with diameters of 1500mm (59in) and 2000mm (79in). The shafts typically penetrated the rock layer from 15-20m (49-66ft). DECL performed six Statnamic load tests with peak test loads ranging from 20.1MN to 21.4MN.
Four of the Statnamic tests were performed at the site ground elevation and two Statnamic tests were performed at the final cut-off elevation of 20m (-66ft). All of the Statnamic tests were performed with DECL's new 20MN Statnamic device, supplied to DECL in 1998 by Berminghammer. Due to physical restrictions, the Statnamic method was the only method possible for load testing at the 20m (-66ft) cutoff elevation.
DECL also performed three static compression load tests (35.3MN, 29.4MN, and 23.9MN) at the site ground elevation, as well as two static tension tests (20.0MN and 20.6MN) also performed at the site ground elevation. Both the static and Statnamic load tests were performed on fully instrumented piles, with some piles having as many as 30 embedded strain gauges. With this information DECL were able to determine the load distribution within each test shaft. The correlations between the Statnamic and static load tests were excellent.
The success of the Statnamic load testing at the Taipei Financial Center has further encouraged the use of Statnamic load testing in Taiwan, and the region.
