[提要]  結(jié)合一實(shí)際工程，進(jìn)行了兩榀框架梁式轉(zhuǎn)換層結(jié)構(gòu)1／5縮尺模型在水平低周反復(fù)荷載下的抗震性能試驗(yàn)，其中一榀的轉(zhuǎn)換梁和與其相連的框支柱采用了鋼骨混凝土結(jié)構(gòu)。試驗(yàn)結(jié)果表明，采用鋼骨混凝土的梁式轉(zhuǎn)換層結(jié)構(gòu)受力和抗震性能明顯優(yōu)于普通鋼筋混凝土梁式結(jié)構(gòu)。
[關(guān)鍵詞]  鋼骨混凝土 轉(zhuǎn)換層 抗震性能 試驗(yàn)研究

Based on the practical project, two scaled models of frame girder transfer floor, one is common reinforced concrete structure (RCTB model) and the other is steel reinforced concrete structure (SRCTB model), are tested subjected to vertical loading and horizontal reversed cyclic loading. The experimental results and preliminary conclusion are given. The experimental results show that the SRCTB modelis superior to RCTB model in mechanical and aseismic behaviour.
