Pullout Tests of Piles In Sand

Offshore Technology Conference, 1976
ABSTRACT Pullout tests on two instrumented piles were performed in a deep deposit of sand at Mustang Island, Texas. Three pullout tests were conducted to determine the tension capacity of a pile, and to assess effects of lateral loading on pullout resistance.

Modeling of The Pullout Test Through the Cell Method

, 2004
The Cell Method (CM) code with auto-matic remeshing for crack propagation analysis [6] is here used for modelling the pullout test. Particular emphasis is given to the analysis in the Mohr-Coulomb plane, since previous numerical models were not decisive in describing failure mechanism in pullout tests.

Fracture analysis of the pullout test

Materials and Structures, 1985
Pullout tests are increasingly being used to determine thein situ strength of concrete. Several studies have shown that a close correlation exists between the maximum pullout load and compressive strength of concrete. However, the failure mechanism of the pullout test is yet not understood.

Tube Pullout Testing Experience

Volume 2: Plant Systems, Structures, and Components; Safety and Security; Next Generation Systems; Heat Exchangers and Cooling Systems, 2012
This paper provides an overview of the use of pullout testing to determine the optimum parameters for assuring reliable tube to tubesheet joints in condensers and heat exchangers. The test is described with typical test methods, equipment and test precautions.

Pullout Tests of Grouted Piles in Stiff Clay

Journal of Petroleum Technology, 1976
This paper describes pullout tests that were conducted in stiff clay near Austin, Tex., to determine the tension capacity of grouted piles and to assess the effect of lateral loading on pullout resistance. In some tests, failures occurred at the pile-grout interface with maximum shearing stresses of 30 psi. In most tests, failures occurred at the grout-

Pullout test model for extensible reinforcement

International Journal for Numerical and Analytical Methods in Geomechanics, 1999
A formulation for the analysis of pullout test on highly extensible planar reinforcement is presented. The non-linear differential equation for pullout mechanism was expressed in non-dimensional form and solved numerically using the Gauss–Siedel technique.

On In-Place Strength of Concrete and Pullout Tests

Cement, Concrete, and Aggregates, 1984
Abstract The current status of in-place strength evaluation of concrete is discussed. A literature survey regarding the controversy surrounding the assessment of concrete strength through field-cast laboratory-cured cylinder tests is presented.

Size Effect in Pullout Tests

ACI Materials Journal, 1988
The results of tests of the pullout strength of reinforcing bars embedded in concrete are reported. The test specimens are 1.5, 3, and 6-in. cubes with geometrically similar bars. The results are found to be consistent with Bazant's size effect law for the nominal stress at softening failures due to disturbed cracking.

Performance of curaua fibers in pullout tests

Journal of Materials Science, 2007
Natural lignocellulosic fibers are successfully replacing synthetic fibers as the reinforcement phase of composite materials in many engineering applications, including automobile parts. In addition to well-known conventional lignocellulosic fibers, others with promising properties, like that obtained from the leaves of the curaua plant (Ananas ...

Rapid Pullout Test of Soil Nail

Journal of Geotechnical and Geoenvironmental Engineering, 2008
This technical paper describes the rapid pullout response of soil nail embedded in dry clean sand. In the rapid pullout test, soil nail is pullout by a tensile impulse load with loading duration that is long enough to eliminate the influence of the stress wave propagation phenomenon. The results of these experiments showed the influence of loading rate
