Direct Shear Test Apparatus – Model TO-105-2

All buildings and structures impose loads on the soil supporting the foundation and this causes stress among the soil particles; failure of this stress results in the sliding of one body of soil relative to the surrounding mass. Tinius Olsen’s direct shear test apparatus is a motorized dead weight testing machine built for direct and residual shear testing on undisturbed and remolded soil specimens. The machine uses a 10:1 beam loading device to regulate confining pressures, a displacement transducer to measure shear and vertical displacement, and a load cell with readout measures shear pressure.
