A three-stories hospital existing reinforced concrete building in the city of Khartoum-Sudan, subjected to seismic loads ,was analysed .The Sudan is not free from earthquakes , it has experienced many earthquakes during the recent history, and the previous studies on this field demonstrated this argument. This paper is focused on the study of seismic performance of the existing hospital buildings in the Sudan. Plastic hinge is used to represent the failure mode in the beams and columns when the member yields. The pushover analysis was performed on the building using SAP2000 software (Ver.14) [1] and equivalent static method according to UBC 97 [2]. The principles of Performance Based Seismic Engineering are used to govern the analysis, where inelastic structural analysis is combined with the seismic hazard to calculate expected seismic performance of a structure. Base shear versus tip displacement curve of the structure, called pushover curve, is an essential outcomes of pushover analysis. The pushover analysis is carried out in both X and Y directions. Default hinge properties, available in some programs based on the FEMA -356 [3] and Applied Technology Council (ATC-40) [4] guidelines are used for each member. One case study has been chosen for this purpose. The evaluation has proved that the three stories hospital building is seismically safe.
