| description | Shear failure is very dangerous because it is brittle and can lead to sudden
structural collapse, so it needs to be solved immediately. The aims of the study is to
determine shear strength from original column and the column retrofit with normal
concrete and resin concrete, increasing of lateral load capacity, stiffness, ductility,
drift ratio, and cracks pattern of the column. Polyester resin concrete is used in this
study as a repairing and strengthening material of columns that have shear failure.
Specimen consists of three pieces column with dimensions of 150 mm x 150
mm, 700 mm high with 8 D 10 longitudinal reinforcement and stirrups � 6-120 mm.
The early stages of testing done by giving a constant axial load of 109 KN and cyclic
lateral load based on ACI T1-1-01 with boundary longitudinal reinforcement
approaching yield and crack width has reached 0.4 mm . After that the column was
repaired and reloaded until it colapse.
The result is resin concrete which contained 20% of resin better than 10% and
15 %. Lateral load capacity of concrete columns retrofit resin increased 1.23 and 1.27
times the lateral load capacity of normal concrete columns retrofit. Drift ratio of
retrofit column is 2.245 %, 2.69 % and 1.963 %, which meets the requirements of
ASCE 7-05 � / L � 1.5 %. Rigidity of retrofit column of 20 % resin is 1.044 times of
retrofit with normal concrete. Ductility factor of resin concrete retrofit decreased 1.13
and 1.21 times lower of normal concrete retrofit. Crack pattern that occur in the
column before and after retrofitting is shear failure. In conclusion, based on
acceptance criteria of ACI T1 - 1-01, column can be used in systems with
intermediate moment frame bearers R ( response modification factor ) maximum 6 . |
