Abstract

In Japan, rockfall retaining walls as safety facilities of roads are designed as the gravity type with a plain concrete structure. In this paper, in order to investigate impact behavior of the structure, prototype impact tests are conducted by letting a steel weight with a predetermined velocity collide. Elasto-plastic impact analyses on the walls are also performed and an applicability of the proposed method is discussed comparing with the experimental results. From this study, the following results are obtained: 1) using the proposed numerical analysis method, weight impact force wave, rotation of the wall, and crack pattern can be precisely predicted; and 2) this analytical me
