Numerical Study of the Strength of Laminated Bamboo Hollow Section Beam and Column Connection Using Glued-In Rod-Steel Box

Article Preview

Abstract:

Previous research on beam and column connections made of laminated bamboo using UNP profiles bracket produced results that were less robust and less rigid. This research was conducted, in which the shape of the coupling steel was altered from a UNP profile to a steel box without a front side. Accordingly, this study aims to ascertain the mechanical performance in the connection of hollow section laminated bamboo beams and columns using glue-in-rod connections anchored by steel boxes. The research employed finite element analysis with the aid of ANSYS software. The results suggest that the moment-rotation relationship curve did not exhibit a peak due to the steel material definition using a bi-linier curve, resulting in the strength value being taken at the yield point across the threaded rod cross-section. The results demonstrate that the strength of the connection is directly proportional to the diameter and number of threaded rods used in conjunction with the steel coupling box. The highest yield strength value, 12.178kNm, was observed in specimen B10-6. In test specimens, B6-4, B8-4, B10-4, and B6-6, the predominant failure mode was a break in the threaded rod. In contrast, test specimens B8-6 and B10-6 exhibited a serviceability failure.This template explains and demonstrates how to prepare your camera-ready paper for Trans Tech Publications.
