EVALUATION OF THE PERFORMANCE OF BIOCOMPOSITE MATERIALS FOR EARTHQUAKE-RESISTANT BUILDING STRUCTURE APPLICATIONS IN DISASTER-PRONE AREAS

Abstract

This study aims to evaluate the performance of biocomposite materials as alternative materials in the application of earthquake-resistant building structures in disaster-prone areas. The research method used is a qualitative approach with a controlled experimental research design, which was chosen to gain an in-depth understanding of the mechanical response and dynamic behavior of biocomposite materials. The research was carried out at the Structure and Materials Laboratory, Department of Civil Engineering, Faculty of Engineering, Gadjah Mada University, Yogyakarta. The research informants consisted of three people, consisting of structural engineering academics, materials researchers, and civil engineering practitioners, who were selected based on their competence and relevance in validating the process and interpretation of research results. The results show that biocomposites have mechanical stability and controlled deformation ability under dynamic loading representing earthquake conditions of medium intensity. These findings suggest that biocomposites have the potential to reduce inertial forces and improve the seismic performance of lightweight buildings. This study recommends further development through higher earthquake intensity testing, integration of numerical modeling, and the development of technical standards to support the application of biocomposites in earthquake-resistant construction.
