This paper presents an analytical approach on the load carrying capacity of steel pipe beams with flange joints against boulder impact by changing the impact position of boulder. First, this method was validated by comparing with the static and dynamic test results. Second, the load carrying capacities of steel pipe beams (fixed and cantilever beams) with flange joints were investigated by changing the impact positions of boulder using the static and dynamic elastic-plastic FEM analyses.
