LI Yuan-yin, JIN Xian-long, LI Gen-guo, et al. Application of precise integration method to analysis of foundation vibration response[J]. 2008, 29(8).DOI:
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.
