[摘要] 為了研究某鋼-混凝土組合結(jié)構(gòu)構(gòu)筑物關(guān)鍵節(jié)點(diǎn)的受力性能和破環(huán)機(jī)理，按照1:2.5的縮尺比模擬實(shí)際工程節(jié)點(diǎn)進(jìn)行了節(jié)點(diǎn)的低周反復(fù)加載試驗(yàn)。本文介紹了關(guān)鍵節(jié)點(diǎn)試驗(yàn)過(guò)程，分析了組合節(jié)點(diǎn)的強(qiáng)度、延性、骨架曲線和滯回性能，根據(jù)試驗(yàn)分析結(jié)果提出了組合結(jié)構(gòu)節(jié)點(diǎn)設(shè)計(jì)建議。

Abstract: In order to verify the mechanical properties of the key joints of a certain special engineering of steel-concrete composite structure system, specimens with 1:2.5 scale are designed based on the actual engineering and tested under cyclic loading. The results of experimental study and theory analysis indicate that the composite joints have enough bearing capacity and good ductility property. Some reasonable suggestions are presented for design of steel-concrete composite structure system and joints based on experimental study.
