Abstract

Moso bamboos have attracted excessive attention as a renewable green building material to the concept of sustainable development. In this paper, the 20 bolted Moso bamboo connection specimens with embedded steel plates and grouting materials were designed according to connection configurations with different bolt diameters and end distance of bolt holes, and their bearing capacities and failure modes were analyzed by static tension tests. According to the test results of all connectors, the failure modes of the specimens are divided into four categories, and the effects of bolt diameter and bolt hole end distance on the connection bearing capacity and failure mode are analyzed. The test results show that the deformation and failure process can be divided into four stages. The main influence factor of connector bearing capacity is bolt diameter. Connectors can be divided into four failure modes, and brittle failure can be avoided by adopting certain structural measures. Filling with grouting material can improve the bearing capacity of joints. Due to the large variability of bamboo, further experiments are needed.
