Seismic Analysis of Peljeac Bridge

The construction of a new 2.4 km long bridge, crossing the sea strait between the Croatian mainland and the Peljeac Peninsula to provide the fixed road link between the whole of Croatia, has just begun. The bridge location is in a highly seismic zone with a design ground acceleration of 0.41g and on extremely bad soil. The 4-lane road bridge consists of 2 approach bridges and the main cable-stayed bridge with continuous steel trapezoidal box superstructure. Nonlinear modal time history analysis, based on superposition of Ritz vectors, but with coupled modal equations, was utilized for seismic design. Real earthquake accelerograms for earthquakes in the vicinity (Bar, Ulcinj, Ston) and also El Centro earthquake, as well as 72 artificial accelerograms, determined by seismic study for the specific bridge location, were analyzed. The analysis was carried out taking into account the proposed construction sequence.
