Shape Control Techniques for Earthquakes Structures in Hospital Buildings Using ETABS Software

Earthquakes are a natural phenomenon that can cause damage to multi-storey buildings such as hospital buildings. The occurrence of earthquakes cannot be predicted, so deeper studies are needed to analyze building structures, especially to minimize ground movements when activities caused by tectonic earthquakes occur. Therefore, a structural analysis model was carried out to fulfill the protection requirements for buildings using the time history method based on Etabs V.18 software with the aim of analyzing the structure of safety requirements according to established standards and reviewing deviations between levels and ATC-40 by considering the total maximum speed. Implementation of the use of Etabs V.18 software in analyzing building structures using the time history method, then to support the analysis of this research, the building model parameters were reviewed using one earthquake accelerogram input. The research results show that in the X direction the largest inter-floor deviation is 50.90, and in the Y direction the largest inter-floor deviation is 50.90. Based on the ATC-40 measurement results, the building is included in the Immediate Occupancy (IO) performance level, with a maximum total deviation value below the limit of 0.01.
