Seismic performance of the inpatient building of Goeteng Hospital, Purbalingga, Indonesia

Abstract

The inpatient building of Goeteng Hospital, Purbalingga, Indonesia, which was built in 2012, is a building with risk category IV. Due to the irregular configuration of the structure, this building has considerable earthquake vulnerability. This study aims to evaluate the symmetrical performance of the Goeteng Hospital inpatient building using pushover analysis. The results of the study show that the basic shear force received by the inpatient building of Goeteng Hospital is equal to 10064.421 and 5655.626 kN in the X and Y directions, respectively. The structure deviation ratio that occurs below 1% is 0.17% for the X direction and 0.24% for the Y direction. Thus, the seismic performance of the Goeteng Hospital inpatient building is categorized as immediate occupancy, where it is predicted that there is no damage, meaning that its structure, strength, and stiffness are about the same as the conditions before the earthquake. Non-structural components are still in place and most are still functioning if the utility is available. The building can still function without the need for repair work.
