چکیده

Experimental studies were conducted by some researchers to investigate the cyclic performance of CFSretrofitted columns; however there is a need to develop analytical methods which can simulate its hysteretic response. This study presents an analysis of the hysteretic behavior of CFS-retrofitted reinforced concrete circular columns. Fiber element analysis was conducted based on cyclic constitutive models of longitudinal reinforcement and concrete confined by both CFS and tie reinforcement. The analysis was verified based on available cyclic test data and analysis provides good agreement with the experimental results. Using the fiber element analysis, the effect of CFS retrofit on the seismic response of a prototype pier was also clarified.

Retrofitting of Existing Rc Square Bridge Columns Using Basalt Frp Rebars

Fiber-reinforced polymers (FRPs) have been widely utilized to improve the seismic performance of deficient reinforced concrete (RC) columns. In recent years, one of the emerging types of FRPs used is basalt fibers. In this study, the performance of existing columns was experimentally examined before and after applying near-surface mounted (NSM) basalt FRP (BFRP) rebars as a retrofitting techniq...

Probabilistic capacity models and fragility estimates for RC columns retrofitted with FRP composites

This paper proposes a probabilistic formulation to assess the effectiveness of the fiber reinforced polymer (FRP) retrofit schemes in enhancing the structural performance of reinforced concrete (RC) bridge columns. Two probabilistic models are proposed to predict the deformation capacities of retrofitted columns. One deformation model corresponds to the flexural failure and the other considers ...

Seismic Behavior of Substandard RC Columns Retrofitted with Embedded Aramid Fiber Reinforced Polymer (AFRP) Reinforcement

Many existing reinforced concrete structures were constructed with substandard characteristics. Low quality concrete, poor transverse reinforcement details and insufficient flexural strength are among the most common deficiencies. While substandard structures are in need of retrofitting, particularly in seismic areas, problems such as high costs and disturbance to occupants are major obstacles ...
