【摘要】：梭柱節(jié)點是傳統(tǒng)風格建筑的特點之一,通過對采用矩形型鋼混凝土柱與鋼筋混凝土圓柱(SRC-RC)梭柱節(jié)點和方鋼管混凝土柱與鋼筋混凝土圓柱(CFST-RC)梭柱節(jié)點兩種不同梭柱節(jié)點的低周反復荷載試驗,比較了不同類型梭柱節(jié)點在不同軸壓比下的受力性能,研究了其承載能力、破壞形態(tài)、滯回性能、耗能能力、變形及延性。試驗結果表明:SRC-RC梭柱節(jié)點和CFST-RC梭柱節(jié)點在試驗過程中均發(fā)生彎剪破壞;各組構件的滯回曲線均比較飽滿,在試驗過程中均表現出良好的滯回性能及耗能能力,抗震性能優(yōu)于普通鋼筋混凝土梭柱節(jié)點;軸壓比的變化對于梭柱節(jié)點的極限承載力和延性有一定影響;CFST-RC梭柱節(jié)點比SRC-RC梭柱節(jié)點具有更好的抗震性能。
[Abstract]:The node of shuttle post is one of the characteristics of traditional architecture. The low cycle cyclic loading tests were carried out on the joints of rectangular steel reinforced concrete column and reinforced concrete column (SRC-RC) shuttle column and square steel tubular column and reinforced concrete column (CFST-RC) shuttle column. The load-bearing capacity, failure mode, hysteretic performance, energy dissipation capacity, deformation and ductility of different types of shuttle column joints under different axial compression ratios were studied. The experimental results show that both SRC-RC shuttle column joints and CFST-RC shuttle column joints are subjected to flexural shear failure during the test. The hysteretic curves of each group of members are full, the hysteretic performance and energy dissipation capacity are good in the test process, and the seismic performance is better than that of ordinary reinforced concrete shuttle column joints. The variation of axial compression ratio has certain influence on ultimate bearing capacity and ductility of shuttle column joints, and CFST-RC shuttle column joints have better seismic performance than SRC-RC shuttle column joints.
