Influence of number of wire mesh layers on the behavior strengthened reinforced concrete columns

الملخص EN

The main objective of the present experimental program is to study the behavior of reinforced concrete short columns subjected to combined axial load and flexure strengthened with ferrocement.

To carry out the investigation, seven columns were tested.

Out of which, one is the control un-strengthened column tested to failure to find out their load carrying capacity, six columns strengthened with ferrocement.

The main objective of the present work is to investigate the effects of ferrocement thickness and number of wire meshes on the load capacity of those columns.

Increasing wire mesh layers from 2 to 5 causes an increase in the ultimate load of the strengthened column with ferrocement compared with the control column.

Using 20mm ferrocement thickness with a 5-wire mesh layers, the ultimate load increases 36.8% when compared with the control column.

Similarly, for 30mm ferrocement thickness with 5 wire mesh layers the increase is 48 %.
