［摘要］竹結(jié)構(gòu)在生態(tài)、工業(yè)化程度、施工速度、保溫節(jié)能和抗震性能等方面具有明顯優(yōu)勢。對竹結(jié)構(gòu)的關(guān)鍵性能進(jìn)行了試驗(yàn),包括竹框架整體結(jié)構(gòu)的振動臺試驗(yàn)、梁柱節(jié)點(diǎn)抗震性能的低周反復(fù)加載試驗(yàn)。結(jié)果表明：竹結(jié)構(gòu)主體框架具有較好的耗能性能和優(yōu)異的抗震性能，但側(cè)移較大；經(jīng)優(yōu)化后的節(jié)點(diǎn)不僅用鋼量最少而且承載力最高、耗能性能好。

Abstract: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.
Keywords:load displacement relationship; vibration table test; node optimization; low frequency cyclic loading test
