SEISMIC RESPONSE OF A LARGE SPAN STRUCTURE SUBJECTED TO OBLIQUE INCIDENT WAVE
|
´˜^i‰pjF
The large span structure constructed above other facilities or buildings is effective for utilization of limited space in city. But because of its scale, it is necessary to consider the differential input motion to its base under earthquake. We performed seismic response analyses of a 100m span structure subjected to oblique incident wave using substructure method. From the result of the analyses, we found some characteristic responses of structure under the condition of oblique incident, and we confirmed the importance of consideration for the differential input motion to the large span structure.
