竹结构在生态、工业化程度、施工速度、保温节能和抗震性能等方面具有明显优势。对竹结构的关键性能进行了试验,包括竹框架整体结构的振动台试验、梁柱节点抗震性能的低周反复加载试验。结果表明:竹结构主体框架具有较好的耗能性能和优异的抗震性能,但侧移较大;经优化后的节点不仅用钢量最少而且承载力最高、耗能性能好。
Bamboo structure in the ecological, industrialization, construction speed, thermal insulation and seismic performance has obvious advantages. The key performance of the bamboo structure was tested, including the shaking table test of the whole structure of the bamboo frame and the low cycle repeated loading test of the seismic performance of the beam-column joints. The results show that the main frame of bamboo structure has better energy dissipation performance and excellent seismic performance, but the lateral displacement is larger. The optimized node not only has the least amount of steel but also has the highest bearing capacity and good energy dissipation performance.
