Retrofitting of Concrete Columns by Conventional Steel Method: Structural Rehabilitation Using Retrofitting Techniques for Damaged Structures Shoaib Afridi

This book gives an insight to check the capacity of retrofitted columns, which will help the designer to restrengthen the damaged structures of earth quake area professionally. The study title ?Restrengthening of Concrete Columns? covers intermediate columns of different concrete strength, with fixed reinforcement ratio and cross-sectional dimensions. Concrete strength varies from 2000 psi to 4000 psi with an interval of 1000 psi. Traditional method of restrengthening is employed by drilling holes and an additional cover is provided along with a cage of reinforcement. The results obtained illustrate remarkable increase (up to 50 %) in the load carrying capacity of retrofitted intermediate columns. This book is a useful tool for Civil engineers having interest in structures rehabilitation.
