[提要] 就兩個不同梁柱剛度比、內置實腹I字鋼的鋼骨高強混凝土(>C75)梁柱十字節(jié)點試件分別進行了低周反復加載試驗,就高強混凝土的作用,型鋼腹板、箍筋、翼緣框等對節(jié)點的抗剪能力貢獻進行了分析,對不同梁柱剛度比的抗剪能力做了對比,并提出了這種結構的節(jié)點抗剪承載力公式。
[關鍵詞] 鋼骨高強混凝土 十字節(jié)點 抗剪The tests of two steel reinforced high strength concrete(>C75) beam-column joints under the cyclic re-
versed loading have been carried out, which vary in the stiffness ratio of beam to column. Shear effect of each part that consists of joint core including high strength concrete, steel web, band and flange frame is analyzed in detail. Shear capacity of joints with different stiffness ratio of beam to column is compared as well. As a result, an equation calculating shear capacity of such joint is proposed.
Keywords: steel reinforced high strength concrete; joint; shear capcity
