Indonesia is a country with a high level of earthquake vulnerability, thus demanding innovation in building structural engineering that is not only safe but also environmentally friendly. In the context of sustainable development, bamboo as an abundant local material is starting to gain attention as an alternative to conventional materials. Bamboo, when processed into composites in the form of fibers or in combination with thermoplastic and thermoset polymers, has been proven to have superior mechanical properties, including tensile strength, stiffness, and resistance to chemical degradation. In addition, the characteristics of water absorption that are controlled through certain treatments make bamboo composites more competitive compared to synthetic materials. The application of bamboo composites in construction is not only limited to new materials in structural elements, but also effective in retrofitting methods. For example, recent research shows the potential of bamboo composites in strengthening reinforced concrete beams and improving the performance of frame systems in earthquake-resistant structures. In line with this, seismic design regulations and standards such as the comparison between SNI 1726:2012 and SNI 1726:2019 demonstrate the importance of adapting structural designs to local seismic conditions. The integration of bamboo composite materials with structural capacity analysis, numerical simulation, and pushover analysis methods has yielded promising results for improving building resilience to dynamic loads. Beyond technical aspects, this approach also supports environmental objectives. Several studies have even developed eco-friendly home prototypes utilizing innovative material combinations, including geopolymer blocks and natural fibers. Thus, the use of bamboo composites not only provides a technical solution to earthquake challenges but also contributes to global efforts to reduce the carbon footprint of the construction sector.

Pushover analysis is a procedure to determine the collapse behavior of a building in an earthquake. The pushover analysis method is widely used by high-level building planners who rely on performance-based planning. The aim of this research is to become a reference in evaluating the collapse performance and behavior of buildings. This research was carried out using SAP2000 software where the structure was modeled in three dimensions. After carrying out the initial load analysis and stress examination, the analysis results showed that the behavior of the building structure was non-linear. This occurs under conditions of higher loads or significant deformation. So the results obtained in the X direction, the maximum displacement value obtained is 0,014410 m achieved with a base shear of 64.746,662 kN. In step 7, collapse (C) occurs in one of the structures marked with a yellow dot. Meanwhile in the Y direction, the displacement obtained is 0,15 m with a base shear of 58.897,495 kN. Based on the structural performance classification according to ATC-40, both in the X direction and Y direction, the building structure is included in the "Immediate Occupancy" category. This means that the structure is able to maintain its function without experiencing significant damage at the given load level. This level of performance is still well below the “Collapse Prevention (CP) limit, meaning that the structure is considered safe under these conditions.
