TYPES OF CRACKS IN R.C.C COLUMNS
Columns are load transferring member of structure. It transfers load from slab and beam to foundation. When an excess loads are activated on column or due to poor quality of concrete or workmanship, it results in a several cracks in column. Types of cracks develop in column are given below : 1. Diagonal crack 2. Horizontal crack 3. Corrosion crack 4. Splitting crack 1. Diagonal crack : This type of crack developed in the column due to insufficient reinforcement and inadequate cross section of column. The main cause for developing diagonal cracks poor load carrying capacity of column. Diagonal crack can affect the soundness of structure hence it needs to be handle properly. 2. Horizontal crack : Horizontal crack in reinforced concrete column is generally found at the beam-column joint, and on column face where tensile stress is massive. Columns with insufficient moment resistance strength, inadequate reinforcements, or disposition of installed reinforcement may l
