Abstract (EN):
Reinforced concrete hollow piers are well known for the shear effects they so often reveal to be subjected to. This aspect is particularly true in the case of hollow piers where the failure modes usually relate to shear behavior. Very few studies have devoted their attention to the economic consequences of repairing and retrofitting the physical damages existing in RC hollow piers subjected to the seismic action. This information is deemed crucial when cost-benefit analysis is concerned for the definition of measures for repair and retrofit of seismic damage. Therefore, the present work intends to discuss adequate strengthening strategies and their costs, associated with each seismic physical limit state of damage. An extensive review of numerous cyclic experimental works on RC hollow piers conducted at the University of Porto will be performed, and in liaise with specialized construction companies, the repair costs will be estimated.
