چکیده
This paper performed compressive tests on corroded reinforced concrete (RC) columns with externally confined ultra-high performance (UHPC) jacket. The studied parameters in this testing program was the corrosion ratio of specimens. influences parameter behavior by UHPC jacket reported and discussed. test results revealed that when rust rate less than 20%, axial cracking typical failure mode unreinforced specimens, cracks rusted area gradually increased increase rate. When reached 30%, protective layer fell off significantly, longitudinal reinforcement also yielded. ultimate load peak displacement specimens were significantly improved, improvement rates two more 80% respectively. specimen a 30% changed to layer. An analytical model proposed predict RC strengthening validations predictions against confirmed accuracy model.

Time-Dependent Structural Behavior of Repaired Corroded RC Columns Located in a Marine Site
The chloride corrosion of reinforcing steel in reinforced concrete (RC) structures is a significant reason for premature deterioration and failure of RC structures in aggressive environments such as Persian Gulf region. This is one of the most important sources of engineering and economic problems in developed countries. So, the repair and maintenance of RC structures exposed to corrosive envir...
متن کاملBehavior Comparison of Uniaxial Cylindrical Columns Strengthened with CFRP
In recent years application of CFRP sheets in the strengthening of the concrete circular column has increased numerously. Knowing the exact behavior of concrete cylindrical columns confined with CFRP is of the first order of importance. ISIS Code of Canada has given relations for strength increase of circular columns confined with CFRP sheets, these relations are defined for a specified range o...
متن کاملFatigue Assessment Model of Corroded RC Beams Strengthened with Prestressed CFRP Sheets
This paper presents a fatigue assessment model that was developed for corroded reinforced concrete (RC) beams strengthened using prestressed carbon fiber-reinforced polymer (CFRP) sheets. The proposed model considers the fatigue properties of the constituent materials as well as the section equilibrium. The model provides a rational approach that can be used to explicitly assess the failure mod...
متن کاملPerformance of Strengthened Non-Uniformly Corroded Reinforced SCC-RAP Members
Abstract: This research examines the performance of strengthened non-uniformly corroded reinforced self-consolidating concrete (SCC) members. This paper focuses on three aspects of concrete including corrosion, concrete cover loss, and repair technique. Up to a 50% corrosion level is considered in this study. Corrosion was experimentally induced and was simulated in other cases. Twenty-six rein...
