Rotational Components of Seismic Waves and Its Influence to the Seismic Response of Specially-Shaped Column Structure

摘要

In this article, the rotational components of Ninghe wave was obtained through the translational components of it using the procedure of Matlab software developed by author, and time history analysis was carried on when the rotational component and the translational components were input to the specially-shaped column frame's space elastoplasticity model which establishes through the ANSYS software simultaneously. The result indicated that the specially-shaped column structure is very sensitive to the rotational seismic component, the effect's enlargement by rotational components should be considered fully when the specially-shaped column structure was designed, and enlarge the frame's seismic safety.
