| Abstract: | Dynamic load effect of ice-cone interaction is studied by using an improved rigid beam model; a formula of dynamic load factor is presented. Some results of the analysis examples are close to those obtained by the model tests and numerical analysis. According to this analysis model, regular patterns obtained by the early stage tests are proved and demonstrated. A distinguishing formula for quasi-static condition is presented also. |
