Abstract
Due to some damage to the structural elements of Andalas University Dental Hospital building, an evaluation of the building structure was carried out. Based on the structural evaluation using Indonesian standard code, SNI 03-1726-2012, it was found that the building is not strong enough to resist the combination loads acting on the structure, especially seismic load. Therefore, the structure should be seismically improved. In this study, there are two retrofitting methods are proposed and analysed: adding concrete jacketing and shear wall. The concrete jacketing method was conducted by enlarging the cross-sectional dimensions and adding reinforcement bar to the structural elements (beam and column) that are unable to resist the working loads. By using the concrete jacketing method, there are many structural components must be strengthened. Therefore, another retrofitting method is proposed, by adding the concrete shear wall. Shear wall is specially designed structural walls include in the buildings to resist the horizontal forces that induced in the plane of the wall due to earthquake forces. From the analysis, it is concluded that the two retrofitting methods are effective enough to reduce the internal forces and displacement of the building. Considering the more effective and efficient work, retrofitting method using shear wall was recommended for strengthening the Dental Hospital building.
