| Abstract: | In high buildings,the deterioration of pillars rigidity will have a certain effect on the mode of structure.The author have made a mode analysis on high building in different deterioration conditions by using ANSYS,and researched the relation and variety trend of characteristic frequency with the change of position and degree of rigidity deterioration.At last,the author made a forecasting analysis on the results by using grey system theory,and established a forecasting model of rigidity deterioration.The forecasting results show that the model proposed in this paper is effective and accurate. |
