Abstract

Abstract

Frame beams in slope protection are often analyzed for internal forces using the Winkler model. Designers usually overlook the frictional force between the frame beam and the slope. Even though the frictional resistance is much smaller than the pre-stress of an anchor bolt, it does exist. Therefore, it should not be ignored in a non-pre-stressed anchor bolt frame. This paper introduces a simple and effective method for calculating internal force with a case study. The results show that this method can help optimize design of the frame beam.
