Abstract
The Faculty of Nursing building is one of the administrative buildings at Andalas University. This building was designed by a planning consultant and began construction in 2013. However, during the construction period, it was found that the concrete quality was very low, that is fc'=14.32 MPa, so that the construction could not be continued because it was not in accordance with the planning quality, fc' =22.39 MPa. Therefore, it is necessary to evaluate the feasibility of the building structure before the construction is continued. In the structural analysis, the loads apllied are dead loads, live loads, and earthquake loads. The analysis was carried out using the application (software) ETABS. Based on the analysis results, it was found that the capacity of columns and beams of the building are not strong enough to withstand the loads acting on the structure. The inter story drift also does not meet the permit limit requirements according to the New Indonesian Earthquake Code, SNI 1726:2019. Therefore, it is necessary to retrofit (strengthen) the structure of the Nursing Faculty Building by re-designing the Detail Engineering Design (DED) on the beams and columns of the plan and jacketing the existing columns. Re-analysis results show that the retrofitted building structure has a strong enough capacity to carry loads acting on the structure and the inter story drift has met the permit limit requirements according to the SNI 1726:2019.

Summary
The Faculty of Nursing building is one of the administrative buildings at Andalas University. This building was designed by a planning consultant and began construction in 2013. During the construction period, it was found that the concrete quality was very low, that is fc'=14.32 Mpa, so that the construction could not be continued because it was not in accordance with the planning quality, fc' =22.39 MPa [1]. It is necessary to have an action to retrofit (strengthen) the structure so that the building can carry the working load. It is necessary to assess of the structure and design retrofitting the structure of the Nursing Faculty Building, Andalas University
