| Abstract: | The joint action of building, pile and board foundation and soil is studied by finite element method. The vibration control ability of pile and board foundation to different frequency excitation is obtained. A processing method for damping is established when structure dynamics is analyzed with direct integration method. Simulating methods of soil in finite element method are discussed. Selecting principles of transition element for small oscillation problem are suggested. |
