由于Andalas大学牙科医院大楼的结构元件受到一些损坏，因此对大楼结构进行了评估。根据印尼标准规范SNI 03-1726-2012的结构评估，发现该建筑物不足以抵抗作用在结构上的组合荷载，特别是地震荷载。因此，结构应进行抗震加固。本研究提出并分析了两种加固方法：加套混凝土和剪力墙。混凝土套壳法是通过增大截面尺寸和在无法承受工作荷载的结构构件（梁和柱）上增加钢筋来进行的。采用混凝土套壳法加固，有许多结构构件需要加固。因此，提出了另一种加固方法，即增设混凝土剪力墙。剪力墙是建筑物中为抵抗地震力在墙体平面内产生的水平力而专门设计的结构墙。分析结果表明，两种加固方法均能有效地减小结构的内力和位移。考虑到加固效果和效率，建议采用剪力墙加固方法对口腔医院大楼进行加固。
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.
