[提要] 鋼梁-鋼筋混凝土柱節(jié)點(diǎn)是鋼-混凝土框架結(jié)構(gòu)的主要傳力部件，認(rèn)識節(jié)點(diǎn)的受力性能對結(jié)構(gòu)設(shè)計(jì)是至關(guān)重要的。通過四個(gè)受反復(fù)荷載作用，軸壓比、節(jié)點(diǎn)構(gòu)造和截面尺寸不同的鋼梁-鋼筋混凝土柱節(jié)點(diǎn)的試驗(yàn)，研究了節(jié)點(diǎn)的強(qiáng)度和變形性能。通過試驗(yàn)研究，使我們對鋼梁-鋼筋混凝土柱節(jié)點(diǎn)在反復(fù)荷載作用下的力學(xué)性能有了初步的認(rèn)識。
[關(guān)鍵詞] 組合結(jié)構(gòu) 節(jié)點(diǎn) 反復(fù)荷載 鋼梁 混凝土柱The mechanical characteristic of the joint of the steel beam-reinforced concrete column has scarcely been studied at home. As the main transfer of the force of the frame structure, the joint takes the important role in the steel-concrete composite structure. Four steel beam-reinforced concrete column joints are tested under the reversed loading. The axial compression ratio, the climension of the reinforced concrete column and the construction of the joint are examined.
Keywords: composite structure; joint; reversed load; steel beam; reinforced concrete column
