Abstract

Timber Instant House (RIKA) is one of the recommended earthquake-resistant houses during the post-disaster reconstruction project. However, in practice, this instant house faces problems with timber material availability. One solution that can be offered is to use Finger Joint Laminated Board (FJLB) material as a structural component. For the design of earthquake-resistant buildings, one of the components that need to be reviewed carefully is the connection component. In this study, the lateral resistance of the FJLB connection with steel will be reviewed. The connection tool used is a bolt. The joints are tested using a monotonic load in the direction parallel to the grain and perpendicular to the grain. The test results on 12 test objects with the ASTM D-5764-97a standard were then compared with the results of manual calculations using the European Yield Model (EYM) theory listed in Eurocode 5. From the test, the average value of the lateral resistance per bolt was 18.63 kN (parallel to the grain) and 15.22 kN (perpendicular to the grain). The ratio between the value of lateral resistance of the test results and theoretical using EYM is close to a value of 1, where most of the connection failure modes from the test results are close to the theoretical connection failure modes. Thus, it can be concluded that applying the EYM theory to the FJLB connection with steel using a bolt connection is still relevant and gives results that are quite close to the test results.
