Abstract
This paper presents direct shear strength test results of tuff taken from Candi Ijo of Jogjakarta, Indonesia where the slopes are considered
in critical condition and need attention. Serial shear tests were conducted to find the normal loads appropriate for direct shear strength
test. The optimum set of normal loads on direct shear strength test for tuff from Candi Ijo were tried by analyzing Mohr & Coulomb
criterion against Hoek-Brown criterion. The study shows that excessive normal load may initiate crack caused by a failure on direct shear
strength test due to the generated shear stress as well as the normal stress. This can be indicated by the unacceptable high value of cohesion
(c)
and
the
low
internal
friction
angle
(ϕ).

Candi Ijo. This research work recommends applying normal loads for direct shear
strength test of tuff are 0.4 kN, 0.6 kN and 0.8 kN. This recommendation was also supported by the analysis using graph suitability of
Mohr & Coulomb criterion and Hoek-Brown criterion.
