Indonesia is a country that has earthquake-prone areas or has a high risk of earthquake disasters. West Java has the largest proportion of the population in Indonesia that is traversed by megathrust, and there are 3 major faults namely the Cimandiri Fault, Lembang Fault, and the Baribis Fault with the Java Megathrust subduction. Vital buildings in Indonesia are expected to withstand earthquakes, including hospital buildings. The concept of earthquake resistant building is the physical strength of the building which consists of structural elements and non-structural elements, especially architectural elements that needs to have small risk of damage. The ceiling construction component is part of the architectural elements. Damage to the components of the ceiling construction due to the earthquake affected the damage to the ceiling construction and the safety of the lives of inpatients. Ceiling construction components can fall on inpatients. There is a possibility that the components of the ceiling construction are sharp, pointed, heavy, which can endanger the lives of inpatients. Damage to the ceiling construction includes minor damage but is a risk to the safety of the patient being treated. Limitations to escape during an earthquake due to the equipment attached to the patient's body and limitations in movement, so the ceiling architectural elements must be earthquake resistant. Hospitalized patients cannot save themselves because of their weak physical condition and unable to move without assistance. When an earthquake occurs, the patient cannot carry out the move independently as a person with normal physical condition. This dissertation research is developing an assessment model for the resistance of non-structural elements to earthquakes in hospital buildings in earthquake-prone areas in Southern West Java. This research is very important and currently there is no research on the development of a performance assessment model for the resilience of sky construction with a patient life safety scheme. Research questions are about how to model the resilience of ceiling construction in hospital buildings in earthquake-prone areas in Southern West Java. The first objective of this study is to identify the level of non-structural damage caused by the earthquake and to analyze the relationship between the level of structural damage and non-structural damage to hospital buildings. The second objective is to identify the pattern of damage to the ceiling construction due to the earthquake and the types of damage that affect the value of the damage to the ceiling construction of the hospital building. The third objective is to formulate an assessment model for the resilience of ceiling construction to earthquakes in hospital buildings. There are three stages of research, namely: correlational-correspondence description analysis, experimental analysis, and correlational analysis. Description analysis is to see the distribution of damage to structural elements, damage to non-structural elements - architectural, and the level of damage to buildings. Correspondence analysis is to identify the identification of building damage due to the earthquake and the level of building damage. Furthermore, at the same stage, a relationship was sought between the degree of damage to structural elements and the level of damage to non-structural elements and the relationship between the level of damage to structural elements and the level of damage to non-structural elements in the physical factors of a particular type and shape of the building. In the second stage, a quasi-experimental analysis method was used to see the effect of the independent variable (independent) on the value of damage to components of the ceiling construction on the dependent variable, namely the value of ceiling damage. The floor deviation values between levels were obtained from the simulation of the SAP 2000 version 24 program based on the modeling of the inpatient buildings of Dr Slamet Hospital and Dr Soekardjo Hospital. This computer simulation is used to see that the inpatient buildings in the two case study hospitals are quite resistant to earthquakes. There is a significant relationship between the level of structural damage and the level of non-structural damage at the previous stage. Although the building is sufficiently resistant to earthquakes, it is not good enough for the non-structural elements of the architecture. There is a shift in the construction of the ceiling due to the movement of the earthquake force. The shift in the construction of the ceiling affects the damage pattern of the construction. The formulation of the results from the quasi-experimental analysis is used as data from the correlational analysis to obtain the effect value of the damage to the ceiling construction components on the damage to the ceiling construction. The assessment model for the resilience of ceiling construction uses several important references in addition to reputable journal articles in preparing this assessment model. The results of this study are 1) there is an effect of the level of damage to structural elements on the level of damage to nonstructural elements due to earthquakes in multi-storey buildings, 2) there is a pattern of damage to ceiling construction due to earthquakes and factors that influence the value of damage to components of hospital building ceilings , and 3) formulation of the assessment model for the durability of ceiling construction components. The assessment model is reflected into the ceiling component damage assessment instrument. The hospital building is the boundary of the building to be assessed. The shape of the building and the type of structure used are also the limits of the assessment. Factors that affect earthquake resistance are used as recommendations for the preparation of instruments in the non-structural element resistance assessment models, especially ceiling construction in hospital buildings. There are 2 novelties and originalities in this research, namely: development of an assessment model for ceiling construction and recommendations for components and ceiling construction for inpatient buildings in earthquake-prone areas.
