Interval Nonprobabilistic Reliability Analysis for Ancient Landslide considering Strain-Softening Behavior: A Case Study

Table 2

Interval variables in the case study.

Interval variables	Units	Range
	kPa	[12.5, 16.8]
	°	[17.9, 24.7]
	kPa	[3.1, 12.5]
	°	[10.6, 17.9]
	—	[0, 0.1]

Note: only the parameters of slip zones are considered with the strain-softening behavior and abstracted as interval variables.
