| Abstract |
The purpose of this paper is to develop a vibration prediction program considering 2-D soil-structure interaction effect in the frequency domain. The program aims to directly apply to vertical vibration response analysis of building structures due to traffic loads. A combined analysis method of finite elements and boundary elements is adopted because it is considered to represent soil-structure interaction better than other methods. In this method, building structures and the near-field soil are modeled by the standard linear finite elements, while the half-space soil is represented using the linear boundary elements in the frequency domain. In order to verify this combined analysis method, experiments are carried out for building structures subject to ground vibration caused by traffic loads. The results from the experiments are analyzed by the program developed and then, compared with the previous experiments related to this subject conducted by the authors. Through the comparison of the results, it is concluded that the combined analysis method, the program developed in this paper, may be used for building structures in a precise manner. Also, graphic user interface is made by the object oriented programming to make an offer for the convenience of practical engineers and investigators. |
