Abstract

In the current paper, different methods of repairing a pre-cracked reinforced concrete beam (RCB) were reviewed and described briefly. Afterward, the near-surface mounted (NSM) technique was used to simulate reinforcement of a pre-cracked RCB using carbon fiber reinforced polymer (CFRP) laminated layer. To do this end, Firstly, based on previous experimental and analytical studies the limitations of the dimensions were specified, and then using Minitab software, Taguchi L9 orthogonal array design of experiment (DoE) was applied to optimize the number of simulations and find the best dimensions for the reinforcement. Subsequently, ABAQUS software was used to analyze the flexural behavior of the NSM-CFRP Pre-cracked RCB. Finally, Force-deflection curves were exported from the simulation results and the best reinforcing pattern was selected

Abstract

Bu makalede, önceden çatlamış bir betonarme kirişin (RCB) onarımı için farklı yöntemler gözden geçirilmiş ve kısaca açıklanmıştır. Daha sonra, karbon fiber takviyeli polimer (CFRP) lamine katman kullanılarak önceden çatlamış bir RCB’nin takviyesini simüle etmek için yüzeye monte (NSM) tekniği kullanıldı. Bu amaçla, öncelikle önceki deneysel ve analitik çalışmalara dayalı olarak boyutların sınırlamaları belirlenmiş ve ardından Minitab yazılımı kullanılarak, simülasyon sayısını optimize etmek ve en iyi boyutları bulmak için Taguchi L9 ortogonal deney tasarımı (DoE) uygulanmıştır. Daha sonra, ABAQUS yazılımı, NSM-CFRP Pre-cracked RCB’nin eğilme davranışını analiz etmek için kullanıldı. Son olarak, simülasyon sonuçlarından Kuvvet-sapma eğrileri dışa aktarıldı ve en iyi takviye modeli seçildi.
