ANALISIS KEKUATAN KOLOM BETON BERTULANG YANG DIPERKUAT DENGAN METODE CONCRETE JACKETING

The December 2004 earthquake and tsunami in Aceh still have an impact on buildings. Korem 012/TU Mess Building Ujong Karang Meulaboh, Province is one of the buildings affected. Structural strengthening required by comparing strength existing building with planned building. structural method used this research concrete jacketing construction method. This study aims to evaluate compare how much column capacity, internal force floor deviation before after reinforced There were several loads assigned structure, i.e., dead, live, wind, loads. As for analysis, load combinations considered. graphical tabular analysis analyzed using SAP2000 Version 22 software making 2 models plans, reinforcement system carried out 1st columns totaling 14 columns. resulted maximum moment, shear force, axial a percentage increase 31%, 23%, 35% respectively. between floors "Y" direction that occurred was 9.686 mm. From it can be seen capacity 3257.30 kN compared 1299.54 strengthening, so there difference 1957.76 capacity.
