Load Tests Sample Clauses
Load Tests. A. The load capacity and overall performance of ground anchors, including load-extension behavior, relaxation and creep, shall be evaluated for acceptance using pre-production tests, performance tests and proof tests in accordance with the requirements of PTI DC35.1.
B. Performance tests shall be carried out on a minimum of 5% of the production ground anchors to confirm the adequacy of the design, materials and method of construction.
1. The performance tests shall be carried out by cyclically and incrementally loading and unloading the ground anchor to a minimum test load of 1.33 times the design load in accordance with PTI DC35.1.
2. The performance tests shall be carried out on ground anchors constructed under methods and conditions identical to those used on the Project.
3. The frequency of performance tests shall be increased when sub-surface conditions are variable and/or the ground anchor load capacities are in question.
Load Tests. A. The load capacity and overall performance of ground anchors, including load-extension behavior, relaxation and creep, shall be evaluated for acceptance using pre-production tests, performance tests and proof tests in accordance with the requirements of PTI DC35.1.
B. A minimum of one pre-production test shall be performed in each anticipated major soil/rock strata at the location of each Structure. Pre-production tests shall satisfy the minimum requirements of the performance test. The test setup, testing procedures and results of pre- production tests shall be reviewed and accepted by the Engineer of Record prior to the installation of production ground anchors.
C. Performance tests shall be carried out on a minimum of 5% of the production ground anchors to confirm the adequacy of the design, materials, and method of construction.
1. The performance tests shall be carried out by cyclically and incrementally loading and unloading the ground anchor to a minimum test load of 1.33 times the design load in accordance with PTI DC35.1.
2. The performance tests shall be carried out on ground anchors constructed under methods and conditions identical to those used on the Project.
3. The frequency of performance tests shall be increased when sub-surface conditions are variable and/or the ground anchor load capacities are in question.
D. Proof tests shall be carried out on all production ground anchors not subjected to performance tests. The proof tests shall be conducted by incrementally loading the anchor up to 1.33 times the design load in accordance with PTI DC35.1.
E. After load testing has been completed, the load in the tendons after seating losses shall be within ± 5% of the specified lock-off load shown on the applicable Final Design.
F. After transferring the load to the anchorage, and prior to removing the jack, a lift-off test shall be carried out to confirm the magnitude of the load in the ground anchor tendon.
1. This load is determined by reapplying load to the tendon to lift off the wedge plate without unseating the wedges.
