竹结构关键性能试验研究

Experimental study for the key performance of the bamboo structure

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。

The bamboo structure shows obvious superiority in terms of ecology,industrialization degree,construction speed,energy-saving insulation and seismic performance,etc. Tests were performed to research key performance including vibration table test of bamboo frame structure and seismic performance of beam-column joints under low frequency cyclic loading test. The results shows that the bamboo frame structure has good dissipation ability and excellent seismic performance,but the lateral displacement is larger. The optimized nodes not only can save steel consumption,but also shows advantage of load capacity and dissipation ability.
