  • In addition, the decrease rate is higher for lower values Confining pressure (MPa)measures averageVolume (mm3)of pressure, where the volumes decrease rapidly between 0 and 10 MPa, and then decrease slowly for higher confining pressures.

  • Confining pressure appears to show little effect in terms of resilient modulus output for these specimens.

  • Confining pressure is the laboratory equivalent of a lithostatic stress field.

  • Confining pressure q equation can be explicated in the form q=q(εc), so that at each axial strain εc the confining pressure q exerted on concrete by the FRP jacket is associated:tual peak confined concrete compressive strain (evaluated for the actual confining pressure q) is εcc.
