Aschheim, Mark A. Inel, Mehmet 2015-09-25T21:03:24Z 2015-09-25T21:03:24Z 10000-01-01 2002 2002 The significant role of embankment flexibility has implications for the seismic design of the substructure columns. Existing procedures, based on force reduction factors, do not account for the significant role played by the embankments. A displacement-based approach for the design of the columns is proposed, in which smaller diameter columns, possibly with higher axial load ratios, are shown to result in improved performance relative to that computed for conventional designs. Guidelines are presented for proportioning the substructure columns to improve their seismic performance. Made available in DSpace on 2015-09-25T21:03:24Z (GMT).
