Concrete—steel bond under repeated loading

Magazine of Concrete Research, 2002
This article reports an experimental study to characterise the concrete–steel bond under repeated loading. Three loading patterns, namely partial unloading, full unloading and multiple unloading were performed. In addition, the non-linear bond behaviour of the concrete–steel interface was studied whereby the initial elastic bonding, non-linearity and ...

Bond under Repeated Loading

SP-180: Bond and Development of Reinforcement - A Tribute to Dr. Peter Gergely, 1998
Characteristic results of more than 100 cyclic pull-out tests are presented including various load histories (simulating realistic load spectra) like random loading or variable amplitude loading with increasing or decreasing tendencies in addition to the constant amplitude loading with different amplitudes.

Repeated compressive loading of a sand

Canadian Geotechnical Journal, 1979
Twelve repeated load drained triaxial tests to at least 105 cycles on a sand are reported. A threshold stress of about 50% of the static failure strength was found. Below the threshold stress, the permanent deformation and resilient modulus reached constant values. Above the threshold stress, the permanent deformation began to increase rapidly and the

Repeated Load Aggregate Degradation

2020
Degradation of a variety of aggregate types, commonly used as ballast by the CN and CP railroads in Canada, and a non-ballast, were evaluated in the laboratory under different gradings, applied stresses, and density conditions. The ballasts were subjected to the one-dimensional and triaxial repeated loading stress states, encompassing some of the ...

Embedment Anchors Subjected to Repeated Loading

Journal of the Geotechnical Engineering Division, 1978
In order to provide a reliable method of estimating the effects of repeated loading on the holding capacity of an anchorage for the purpose of designing embedment anchor systems for long-term use, tests were performed on circular plate anchors connected to a rigid tie shaft which were placed in a medium, uniform saturated sand.

[Repeated ergometric loading].

Vnitrni lekarstvi, 1989
The action of cardioactive substances is tested by repeated ergometric loads. The aim of the present work was to assess whether after previous loads in the organism certain adaptational changes persist, cardiovascular, respiratory or metabolic, which might influence the course of a subsequent load.

Repeated load testing of a granular material

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1974
Both the resilient and permanent strains were measured and shown to reach equilibrium values after some 10 4 stress cycles under drained test conditions. The effect of changes in both the mean level and the amplitude of the deviator stress were studied and samples were tested at various constant cell pressures.

Reinforced Concrete Beams under Repeated Loads

Journal of the Structural Division, 1969
This paper describes the results of an experimental program of the effect of repeated loads on the rotation and load carrying capacity of reinforced concrete beams. Comparing results obtained under repeated loading with results obtained on similar specimens under single loading showed that neither the rotation nor the load carrying capacity of a ...

Structural Safety Indices for Repeated Loads

Journal of the Engineering Mechanics Division, 1978
Approximations for the distribution functions of the extremes in a number of repetitions of a random variable are developed based on the crossing approach. Results are obtained for independent repetitions and Gauss-Markov correlated sequences and processes.
