Abstract

A new design was proposed in which the Engineered Cementitious Composites (ECC) was used to improve the seismic behavior of the reinforced concrete hollow bridge piers. The ECC jacket was used both in and out of the cross section of the hollow bridge piers to improve the strength and ductility of the reinforced concrete hollow bridge piers. Also, the ECC would increase the anti-cracking behavior of hollow bridge piers, which would be of particular importance for the durability of the bridge piers. A numerical analysis model for the reinforced concrete hollow bridge piers retrofit with ECC was built, and the seismic behavior of the piers was studied. It is found that the strength and ductility of the piers could be increased by using ECC, which indicates effectiveness of the ECC jacket for seismic retrofit of hollow bridge piers.
