Seismic behavior of chilean bridges with seismic protection devices

Several bridges with seismic protection systems have been built in the last decade in Chile. Accelerometer networks have been installed in some of them. Seismic records have been obtained by these instruments for moderate and severe earthquakes. In this paper, records registered at Marga Marga Bridg...
