This study evaluates the structural performance of J-Bolt connections made from Kawayan Tinik (Bambusa blumeana), focusing on the effects of varying bolt diameters and the presence of mortar infill. Using laboratory experiments and finite element analysis (FEA) via ANSYS software, the research addresses the growing demand for sustainable construction materials amid a projected global population of 9.7 billion by 2050. Bamboo, with its rapid growth cycle and reduced environmental impact, presents a viable alternative to carbon-intensive materials like steel and concrete, particularly in the Philippines, where housing demand and natural disasters pose challenges. A quantitative approach was adopted, testing six T-Joint bamboo samples across various bolt diameters, with a total of 36 samples. Compressive and tensile strengths were evaluated per ASTM D5652-21 and ISO 6892-1 standards. Results revealed that bolt diameter significantly influences the tensile and compressive strengths of T-Joint bamboo connections. While splitting failures were observed in all bolt sizes, 12 mm diameter bolts exhibited superior performance, with reduced likelihood of punching shear failure and no bearing failure, achieving the highest ultimate compressive load capacity (34.28 kN). The findings affirm bamboo's potential as a sustainable building material, aligning with green construction principles. ANSYS
simulations closely mirrored laboratory observations, validating the structural behavior of J- Bolt connections. It is recommended to use 12 mm bolts with mortar infill for optimal
performance. Future research should explore the long-term durability of bamboo connections under diverse environmental conditions and the integration of other sustainable materials for resilient and eco-friendly infrastructure.
