Ductility of Retrofit Column Using Wire Mesh and Self Compacting Concrete Due to Lateral Cyclic Load

Abstract

Poor construction and ductility are the causes of structural damage and failure in earthquakes. Retrofitting is a way of repairing the damage and increasing the ductility of the column. Selection of wire mesh and self-compacting concrete as retrofit material, as it is easy to process and easy to obtain. The test specimen consisted of 3 columns with a size of 300x300 mm, consisting of a control column (KK), a completely retrofitted column (KR-1) and a retrofitted column in the approximate plastic hinge area (KR-2). The samples were cyclically tested based on the displacement control method. The test results show that the retrofitted with wire mesh and self-compacting concrete has a higher ductility value on the approximate plastic hinge area (KR-2). In addition, the retrofitted column has a higher load-bearing capacity than the column that has not been retrofitted.
