Building Performance Based on Seismic Conceptual Design in Temporary Housing Semeru Eruption 2021

Abstract Indonesia’s geographical location, which often experiences earthquakes, is important in disaster mitigation programs, especially for earthquake-resistant building planning. This study uses quantitative and case study methods to determine the seismic performance in the design of temporary housing for the 2021 Mount Semeru eruption based on the Seismic Conceptual Design of Buildings. The analysis used a scoring method to measure the similarity of the case study object to seismic theory. The damage caused by the eruption, relocation of settlements, and construction of new houses are very necessary. The 2000 temporary housing units were designed using fast materials, such as light steel and gypsum board, which is not suitable for the main structure of the building. However, with a building area of only 28.8 m2, the building span is shorter, and only one floor with room partitions inside makes the structure more solid. Each building is also given a distance from another building so that vibration waves that hit the building do not spread to other buildings. From the analysis results, the design of this temporary housing has a similarity of 65.9% with the seismic theory. This design has a fairly good building performance in terms of security and safety to reduce the risk of earthquake damage. However, more detailed drawings are needed, such as structural connection systems, technical specifications, and construction guidelines, and there must also be calculations of structural strength by experts.
