crushing failure of concrete column

Sep 13, 2014· Based on the slenderness ratio of thecolumn, there are three modes offailureof reinforcedconcrete columns. Thecolumnsare assumed to be centrally loaded (no eccentric loads). Mode – 1:Column Failuredue to Pure Compression: When reinforcedconcrete columnsare axially loaded, the reinforcement steel andconcreteexperiences stresses.

Dec 06, 2014· Rankin’s formula is also known as Rankin Gordon Formula. It gives the ultimate load thatcolumncan bear beforefailure. Ifcolumnis short, calculated load will be known ascrushingload. And load will be buckling or crippling load, in case of longcolumn. This formula only gives the ultimate load, butcolumnsare design on safe load.

2- BucklingFailure. 3- ShearFailure. 1- CompressionFailure. Whencolumnsare axially loaded, theconcreteand steel will experience some stresses. When the loads are greater in amount compared to the cross-sectional area of thecolumn, theconcreteand steel will reach the yield stress andfailurewill be starting without any later deformation.

Dec 10, 2014·Failurepattern of shortcolumnis totally different than longcolumnpatterns. Shortcolumndirectly fails at the maximum value of direct stress it can take. In result of this,columnmaterial fails and get crushed. Longcolumnbuckles on the application of load. Bending stress produces in result of buckling which results incolumn failure.
