Research Progress in Mechanics of hollow section RC bridge piers subjected to seismic dynamic load

The seismic performance of the bridge piers is a basic study in seismic analysis of bridges. Hollow section piers have high bending strength and stiffness, as well as reduced amount of reinforced concrete needed and thus good economic returns, which have been widely applied in the high-pier, large-span bridges in high-intensity area of western China. Current study status and future development trends about the seismic behavior of hollow section reinforced concrete piers were presented. The necessity of carrying out seismic performance studies of hollow section reinforced concrete bridge piers was also pointed out.
