Direct Shear Apparatus as per IS-2720 (Part 13).

AMOUNT AS PER INQUARY

Direct Shear Apparatus as per IS-2720 (Part 13). The apparatus consists of a square box divided into two halves. The specimen contained in a box, is subjected to a constant normal load while increasing horizontal force is applied to one of the sections of the shear box. The force causes a shear failure along the juncture between the box sections. The shear force and normal load are measured directly. It is provided with a turret type gear box to get 12 different constant rates of strain i.e. 1.25, 0.625, 0.25, 0.125, 0.05,0.025, 0.01, 0.005, 0.002, 0.001, 0.0004, and 0.0002 mm/min The loading unit has V-strips on which the shear box assembly rests. The pre-calibrated load yoke helps counterbalance the loading system. The load yoke with direct and through level system for applying force up to 8kg/cm2 capacity, fixtures for proving ring, brackets for holding consolidation and strain dial gauges are provided. The lead screw connected to the shear box housing helps application of shear stress. The apparatus consists of shear box assembly, shear box, plate gripper plate, perforated gripper plate, porous stone, top loading pad, base plate, shear box housing, weights, proving ring and dial gauges.
