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 کاملFatigue Life of Repaired Welded Tubular Joints
In this study, the effect of repair on fatigue life of tubular joints is investigated. Six cracked specimens precedently subjected to fatigue loading undergone to weld repair. Two of those specimens were shot peened before primary fatigue loading. It is shown that repair gives rise to about 150% increase in fatigue life for original specimens while the increase of fatigue life for shot-peened ...
متن کاملتاثیر تعمیر مکرر بر ریزساختار، خواص مکانیکی و رفتار خوردگی مقاطع جوشکاری شده آلیاژ آلومینیم 321H-5083 به روش میگ پالسی
In the marine industries, defects in welded joints are repaired to improve the performance. It is possible that a welded joint is repaired once or twice. In this research, effect of repair on microstructure, mechanical properties and corrosion behavior of welded joints of 5083-H321 aluminum alloy using pulsed MIG process was investigated. The results show that excess heat due to increasing the ...
متن کاملCorrosion Fatigue of 17-4pH Stainless Steel in a Simulated Sea Water Solution
Since martensitic precipitation hardened 17-4pH stainless steel has been widely used in corrosive environments, evaluation of its corrosion fatigue behavior is important. In this research, after microstructural studies, mechanical, corrosion, fatigue and corrosion fatigue tests were performed on 17-4pH specimens. Fatigue and corrosion fatigue tests were carried out at the stress ratio of -1 an...
متن کاملThe Analysis of Longitudinal Shrinkage in Butt Weld Joint (TECHNICAL NOTE)
In this research longitudinal shrinkage of two steel plates with identical thickness that are joint together through butt welding and another steel plate with bead welding. This study begins withthe introduction of a model, in which the thermoelastoplastic zones near the weld line is simulated with a thermoelastoplastic flat bar, and full-elastic areas beyond the weld line is simulated with a f...
