In Eqns (9) and (10), the unknown parameter is only the confining pressure, and it can be deduced by an analysis of steel tube subsequently.
Meanwhile, the confining pressure on the concrete coming from circular steel tube can be written as:
The mechanical behavior of Anvil Points oil shale at elevated temperatures and confining pressures
// Canadian Geotechnical Journal.
Findings based on large scale triaxial testing indicate that a small increase in confining pressure ([[sigma]'.
Effect of confining pressure on the degradation of ballast under cyclic loading", Geotechnique, Vol.
As a result, there is a good bonding action exist between the CFRP strips and steel tube and also external bonding of CFRP strips considerably provided the confining pressure
to the column were proved.
The cyclic shear stress depends on confining pressure at relative higher density.
1) China Institute of Water Resources and Hydropower Research (IWHR) developed the wave velocity testing apparatus and testing demarcates technique of laboratory large-scale triaxial apparatus, which improved the testing precision up to 10-4s to 10-6s, and also improved and perfected the testing method for dynamic deformation properties of coarse granular soil from a range of small strain to large strain under max confining pressure, 1Mpa with the wave velocity testing apparatus of large-scale dynamic triaxial test combined with testing large-scale samples, proposed in the 7th 5-year plan period,
The bigger the confining pressure
is, the bigger the shearing strength is.
With increasing of the number of layers, lateral confining pressure
Influence of confining pressure
and cyclic deviator stress on liquefaction based on reconstituted samples between natural sand and caolinite clay.
Based on the results, it was found that the deformability of RC beams increases as the degree of reinforcement decreases or confining pressure
So the reduced confining pressure
in a square section due to the concentration of stresses at the corners is solved by using a square section with circular corners.
The lower density bands appeared in the centre of specimen at a lower confining pressure
and spread to the edge due to the weak internal coherence.
This is because the reinforcement provides a continuous confining pressure
around the circumference of the circular section and results in the increased concrete strength and ultimate strain.
