| Abstract: | The Maattanen Model used only for single-legged structures cannot express the features of multilegged structures.The latest results of studies on ice forces acting upon multilegged structures are introduced into the method in appying the Maattanen model to a multi-legged structure. According to the method,a computer program for analysis of ice excited vibrations of multi-legged structures is compiled and used in analyzing a practical engineering example.The results are in good agreement with the full scale test results,showing that it is a practical tool in the analysis of ice-induced vibrations for engineering purposes. |
