Abstract
DIAGNOSIS AND PERFORMANCE EVALUATION OF REINFORCED CONCRETE AND FRP RETROFITTED COLUMNS OF EXISTING BUILDINGS
Dr. Chandrakant B. Pol*
ABSTRACT
Structural Health Monitoring is relatively new concept across the worldwide and very recent for India. It has proved to be effective and fruitful in many countries, now being practices often, and has a great potential and usefulness for India. India has a rich cultural and historical background which is very well reflected in the varied amount of historical structures. These structures are very well built and have withstood the test of time. But due to their historical importance it becomes very important to assess health condition of these structures, so that appropriate steps may be taken before it is too late. In the present work, Structural Health Monitoring of 62 years old hostel building situated in Walchand College of Engineering, Sangli is carried out along with the performance analysis of building in ETABS and identifying defects in the structure which may cause the instability. This research work pertains to identify and retrofit the major structural components such as columns with the help of advanced techniques (CFRP Confinement). Furthermore, the provided CFRP confinement is validated through the FEA based (ABAQUS) simulation of columns. From, the result it is observed that strength and ductility of the column is increased by 30-50% by using such CFRP confinement.
