Some Observations on Reliability-Based Design of Rock Footings

This paper continues our development of a simplified reliability-based design method for rock footings in an LRFD format. Two issues are addressed herein: the robustness of the empirical model and the proper approach to evaluate the rock strength variability. Results of simulations using three calculation models indicate that the empirical model is reasonably conservative and that the strength variability to be used in the calculations is that of the rock mass, not the intact rock.
