FULL SCALE TEST AND NUMERICAL ANALYSIS OF BAMBOO TRUSS STRUCTURE WITH HAND-MADE ROPE JOINT

– Study on design of temporary building using bamboo as structural material –

Abstract

In our previous study, we proposed the joint-making method for constructing temporary emergency buildings in areas affected by hazards using gaffer tape and rope to construct bamboo structure and discussed the allowable strength of joints. However, we have not examined the precise restoring force properties of joints. In this study, we first construct a restoring force model for a single joint based on experimental results. Next, we apply the model to a simple full-scale truss and conduct numerical analysis. Finally, we discuss the validity of the model by comparing the numerical results with the experimental results on the actual truss.
