steel connectors were used to ensure optimum transmission of the forces generated by the root-bearing structure and the supports into the bamboo. these steel connectors were inserted into the open, hollow cavities on the outside edges of the process of cement hydrationn, the concrete hardened, as a result, the load-bearing capacity of bamboo canes was determined not only by the bamboo itself but above all else by the effect of the composite in the connection area of lean-mix concrete and the bamboo's inner shell
