Experimental study on compressive performance of the multiple-culm bamboo columns connected by bolts
Abstract The compressive performance of the multiple-culm bamboo columns (MCBCs) connected by bolts has been experimentally studied in this paper. The effects of distance of the bolts, length and cross-section of the columns on the load-bearing capacity of the specimens as well as the failure modes are reported. Also, the compressive behavior of the MCBC with and without truncated bamboo is discussed. The results show that the reasonable distance of the bolts of the MCBC has minor effect on the bearing capacity of the specimens, while the length and cross-section of the columns have obvious effect on it; both global and local instabilities are the common failure models of the MCBCs under axial loading. Moreover, the fabrication of the connection at the truncated location does not decrease the compressive resistance of the MCBCs compared with the specimens without connections. The bearing capacity of the MCBC calculated by the method from Wood Structure Design Standard is close to the test value when the slenderness ratio of it is large.
Highlights The effects of distance of the screws, length and cross-section on compressive performance of MCBCs are reported. The compressive behavior of MCBCs with and without truncated bamboo is assessed. The stable bearing capacity of MCBCs is studied.
