DIRECT SHEAR
Information of Shear values plays an important role the design of
sub-structures in determining bearing capacity of soils, design of
retaining walls, instability calculation earth slopes etc. Various Shear
Apparatus are available and Direct Shear Apparatus is one of them.
In Direct Shear test specimen contained in a box is subjected to a
constant normal load and increasing horizontal load is applied to the
upper section of the specimen. Shear force and load are directly
measured.
Direct Shear Apparatus (Manually) (SL-GT-050)
AS PER IS: 2720 (Part-VIII), ASTM D-3080

For determination of the direct shear strength of soils on specimen
size 60 mm x 60 mm x 25 mm.
Specification: The apparatus comprises of the following:
Loading Unit: Supplied with load yoke with direct and lever system
for applying load. Normal stress capacity 8kg/sq.cm. Load is applied
either directly of through a counter balanced detachable lever.
Provision is made for load to be applied either through a steel ball
recessed in the loading pad or direct through a boss on the pre
calibrated loading yoke. The loading unit is provided with V strips
and roller strips for frictionless movement of shear box housing.

stones, one top loading pad. Shear box housing: Accommodates the
Direct Shear Box assembly. Complete with two ball roller strips.
Specimen Cutter: For cutting 60 x 60 x 25 mm specimen from larger
samples. Set of weights to give a normal stress of 3 kg/sq.cm.
