2) In Dalian University of Technology, Dynamic deformation properties of sand from small strains to large strains are tested on a medium and a small dynamic triaxial apparatus with testing set up for local axial strain at the stress level of max confining pressure from 0.
5) In order to reduce the seismic deformation of dam, it is better to study out reliable engineering measures in the aspects of high quality fill materials, enhancing fill density, increasing the confining pressure, and seepage control and reducing saturated water zoon.
Yamamuro and Lade (1998) found that the steady state line of silt under drainage condition and undrainage condition was the same line within the limit from 200 kPa to 1000 kPa confining pressure.
It has great influence for the factors: confining pressure, initial dry density, initial water content, shearing rate and drainage condition to the characteristics of stress-strain of soil.
However, fibre orientation (more than 0[degrees]) leads to the applying less confining pressure to concrete core and concrete specimens exhibit less axial stress.
Relationship between confining pressure, number of cyclic stress and cyclic deviator stress parameter on every sample.
Confining pressure used in cyclic triaxial test is limited by 25 kPa, 50 kPa, and 100 kPa on reconstituted sample of clayey sand.
Based on Figure 3, more increase confining pressure applied on every sample will enlarge cyclic deviator stress to liquefy the sample.
There were five assumptions made in the analysis: (1) plane sections before bending remain plane after bending; (2) the tensile strength of the concrete may be neglected; (3) there is no relative slip between concrete and steel reinforcement; (4) the concrete core is confined while the concrete cover is unconfined; (5) the confining pressure provided to the concrete core by confinement is assumed to be constant throughout the concrete compression zone.
co] was varied from 40 to 100 MPa, the confining pressure [f.
bo] for various concrete strengths and confining pressure are listed in Table 1 for different yield strength of tension steel (Ho et al.
