Seismic response of a base isolated cable-stayed bridge under near-fault ground motion excitations / Ahad Javanmardi … [et al.].

Nowadays, development of cable-stayed bridges is increasing around the world. The mitigation of seismic forces to these bridges are obligatory to prevent damages or failure of its structural members. Herein, this paper aimed to determine the near-fault ground motion effect on an existing cablestayed...
