The Kauman Baru Public Health Center Building in Ponorogo Regency has an asymmetrical floor plan configuration, making it potentially susceptible to greater deformation under earthquake loading. This study aims to analyze the structural deformation of the building using the response spectrum method based on SNI 1726:2019. A quantitative research method was employed using secondary data, including construction drawings, technical data, and material specifications. Structural modeling and analysis were carried out using SAP 2000 software. The analysis results indicate that the maximum structural deformation due to earthquake loading is 0.0187 m, while the allowable deformation limit according to SNI 1726:2019 is 0.06 m. Therefore, the structural deformation remains below the allowable limit, indicating that the Kauman Baru Public Health Center Building in Ponorogo Regency satisfies the deformation requirements and is considered safe against earthquake loading.
