This project deals with the problems of the effects of differential             (phased) ground motion to the response of bridge structures.  Multiple-         support excitation is considered.  Records from dense instrument arrays         and synthetic ground motions are used.  Emphasis is placed on the               stochastic method of dynamic analysis.                                                                                                                          The results of this research is expected to have practical impact on the        practice:  to be incorporated in the seismic analysis computer programs         such as SEISAB and the general guidelines for the seismic analysis and          design of bridges.                                                                                                                                              This is the second-year research of a 2-year continuing project                 originally initiated at the Princeton University.
