［摘要］傳統(tǒng)風(fēng)格建筑結(jié)構(gòu)中關(guān)鍵節(jié)點(diǎn)的性能對結(jié)構(gòu)性能的影響至關(guān)重要，分別進(jìn)行了2組節(jié)點(diǎn)試驗(yàn)，區(qū)分考慮斗拱構(gòu)件對節(jié)點(diǎn)性能的影響，且每組試驗(yàn)有2個試件，軸壓比分別為0-3和0-6。試驗(yàn)結(jié)果表明：未考慮斗拱作用節(jié)點(diǎn)（ZL1系列）的破壞主要集中于上下柱交接焊縫區(qū)域，而考慮斗拱作用節(jié)點(diǎn)（YL1系列）的破壞主要集中于上下柱櫨斗處和節(jié)點(diǎn)短柱區(qū)域，且櫨斗部位破壞較早，變形較大；ZL1系列試件相比YL1系列試件節(jié)點(diǎn)承載力低，剛度與強(qiáng)度退化慢；在此基礎(chǔ)上給出工程設(shè)計(jì)建議和加強(qiáng)構(gòu)造措施。

Abstract:The performance of key joints in the traditional building structure has an important influence on the performance of the whole structure. Therefore, two series of tests were conducted to discriminatively consider the influence of brackets component on performance of joint, and each series of tests have two specimens with axial compression ratio 0.3 and 0.6 respectively. The experimental results show that without considering the effect of node brackets (ZL1 series) damage mainly concentrated in cap block at the upper and lower column or short column node region, and considering the effect of node brackets (YL1 series) damage mainly concentrated in the upper and lower column and short column node region, and brackets parts damage early, deformation is large. Compared with YL1 series, the joint bearing capacity of ZL1 series is relatively lower, the brightness and strength degrade more slowly. Based on the mentioned above, some key joint strengthening methods and design recommendations were given during a construction procedure.
Keywords:traditional style building; key joint; bracket component; construction measure
