Repeated loading on single piles in sand

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1980
Nondynamic repeated load tests were conducted on single friction piles embedded in a medium dense sand. The 19-mm (0.75-in.) diam pile was instrumented to measure the distribution of axial loads along the shaft. It was found that the response of the pile to repeated loads is governed by the: (1)Type of load; (2)amplitude of load; anf (3)number of ...

Repeated and Dynamic loading

1991
The response of deep foundations to repeated dynamic loading has been a subject of considerable interest in recent years in relation to the seismic design of important structures such as nucIear power plants, offshore structures and vibrating machines, etc, In spite of significant efforts on the part of theoretical and experimental researchers and 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.

Apparatus for Repeated Load Tests on Soils

1960
In recent years there has been a considerable awareness among soil engineers concerned with highway and airport construction of the need for studies of the behavior of soil under repeated loading. Studies conducted by the State of California Division of Highways (1)3 for example, have shown that highway pavements may fail by fatigue as a result of the ...

Trends in Deflection with Application of Repeated Loads

Transportation Research Record: Journal of the Transportation Research Board, 2008
Falling weight deflectometer (FWD) testing is now considered routine for the evaluation of pavement structures. Averaging of FWD load and deflection data collected at the same location and similar drop loads is common before further analysis. The stated reason for this averaging is to decrease the effect of the random error inherent in FWD deflection ...

Effects of Repeated structures Thermal Loading

Aircraft Engineering and Aerospace Technology, 1960
A very simple redundant structure is subjected to temperature cycling, primarily to determine the influence of the yield stress/temperature relation on its behaviour: the range and periodic time of the temperature cycle are included as subsidiary variables.

Strength of Aeroplanes in Relation to Repeated Loads

Aeronautical Quarterly, 1950
SummaryThe present position relating to the effect of repeated loads on aircraft structures is reviewed from the point of view of the capacity of aircraft structures to withstand such loads and also of their frequencies of occurrence in the life of the aircraft.A rough account is given of the statistical methods by which such frequencies can be ...

[Human tolerance to repeated +Gz loads].

Kosmicheskaia biologiia i aviakosmicheskaia meditsina, 1978
Centrifugation experiments were carried out to study human tolerance to repeated acceleration +Gz of 7.5 and 8.5 G as maximal and 1.2 and 3.0 G as minimal values. The exposures were no longer than II min with the onset rate of 0.3 to 0.8 G/sec. Repeated exposures to acceleration changed their tolerance by test subjects.
