000009490 520__ $$2eng$$aA Displacement-based seismic design procedure is proposed and elaborated for concrete bridges with continuous deck integral with the piers. It includes a simple estimation of inelastic deformation demands (chord or plastic hinge rotations in piers, curvatures for the deck) via elastic 5%-damped modal response spectrum analysis. The applicability of the equal displacement rule at the level of member deformations is checked through nonlinear dynamic analyses of eight representative bridges, regular or irregular, with three or five spans, all with a prestressed concrete box girder and piers of various cross-sections and about equal or very different heights. The procedure gives more cost-effective designs than the conventional force-based approach of Eurocode 8, without loss in seismic performance under ground motions well beyond the design motion.
