Energy Dissipation in Laminated Bamboo Hollow Section Beam and Column Connection Using Glued-In Rod and Bracket

Article Preview

Abstract:

The previous research on beam and column connections made of laminated bamboo with steel brackets has been tested under static loads. Furthermore, these connections need to be studied for their performance in terms of energy dissipation. The test specimens will be subjected to two-way lateral (cyclic) loading treatment. The testing and analysis standards used include ASTM E2126-11, AISC 360-16, Eurocode 1993-1-8, and Eurocode 1998-1. The results showed that the configuration of the number of thread rods used and the size of the thread rod cross-sectional area affected the moment values achieved. In addition, the trends formed in the curves show that the first loading cycle has a greater bending moment capacity than the second loading cycle. The results show that loading history, bracket usage, configuration, and thread rod cross-sectional area affect the dissipation energy values; the highest dissipation energy value is 527.89kJ for 10.6 configuration specimen and the smallest dissipation energy value is 159.80 kJ for 6.4 configuration specimen. Additional results show that test specimens with six thread rod configurations are classified as medium energy dissipation class (DCM), and test specimens with four thread rod configurations are classified as low energy dissipation class (DCL). Test specimens with configurations 6.4, 8.4, 8.6, 10.4, and 10.6 showed service failure.
