Abstract : The connection is the most critical part in a wooden structure because it plays a direct role in transmitting forces between elements. This study analyzed the behavior of two Palapi wood (Heritiera simplicifolia.) joints using a single bolt based on the European Yield Model (EYM) method referring to SNI 7973:2013. The parameters reviewed included the physical properties of wood, mechanical properties, wood bearing strength, bolt flexural strength, and theoretical and experimental connection capacity. The test results showed an average water content of 11.50% and a density of 0.43 g/cm3. The average shear strength parallel to the grain reached 19.21 MPa, the compressive strength parallel to the grain was 25.63 MPa, and the wood bearing strength increased with increasing bolt diameter. Comparison of the theoretical EYM results and the experimental results showed a significant difference, mainly influenced by the failure of the wood bearing and the plastic deflection of the bolt. The results of this study are expected to be a reference in designing wood joints more safely and efficiently, especially for the use of local Palapi wood in construction.
