| Abstract: | Abstract ：Through comparing the difference of internal power through using Midas-Civil set up a three-dimensional model and standard calcula- tion. We found that the internal force that calculation from Midas-Civil set up a three-dimensional model of the spatial beam element is highest. So we think the best way to calculate deep-waterbridge high pier earthquake dynamic water pressure at the earthquake in the reservoir area is using Midas-Civil Set up a three-dimensional model. |
