Abstract
The key point of this thesis is integrating the soil-structure interaction system into the response spectrum method. Base on the traditional response spectrum method then adding the soil-interaction elements to get closer to the true response.
The first purpose of simplified method is reducing the computation. Use the simple and convenient additional equivalent parameters to simulate the soil instead of the finite element method which is more complication. Get the additional mass, damping and stiffness parameters quickly and integrate into the combination system to modify the response of structure.
Use modified combination system and takes soil affect in to condition to simplify the response structure method. Then it can be easily used by the basic components of structure and secondary system, for example the first period, damping ratio and the structure which it is connected, and use the design spectrum directly. In the chapter 5, 3 calculating examples shows the process of simplified method and compared with the state space solution, to check the applicability of the simplified method.
