An Applied Compute Method for Mutual Action of Box Frame and Spring Foundation

This paper according to the direct harmonic displacement between the Colum foot of box frame and foundation, also from the result of paper 2 , providing a Semi-analysis Semi-discrete method Compute the mutual action of box frame and Spring foundation. Giving out three relative closing formula compute the reaction of colum foot and displacement of colum foot and the foundation's re ction, Made the entir Work of computing evidently.
