| Abstract: | The precise integration method is a high precision algorithm for structural dynamic response. The method is applied to foundation vibration response. In order to reduce storage requirement, matrix-vector multiplication that saves storage, and series solution are adopted; moreover, the precision of precise integration method isn’t affected. A corresponding program is developed for analysis of foundation vibration response. A building foundation of an important project is analyzed. The results are compared with the results of Nastran, a famous finite element analysis software; and correctness of above-mentioned methods and program is validated. |
