[摘要]為解決型鋼混凝土梁柱節(jié)點(diǎn)處構(gòu)造復(fù)雜與施工困難的問題,提出了構(gòu)造簡單且便于施工的節(jié)點(diǎn)核心區(qū)采用U形拉結(jié)筋和梁端型鋼腹板開矩形孔的兩種型鋼混凝土梁柱節(jié)點(diǎn)。為考察兩種新型型鋼混凝土梁柱節(jié)點(diǎn)和普通型鋼混凝土梁柱節(jié)點(diǎn)抗震性能的區(qū)別,對3種不同形式的9個型鋼混凝土梁柱節(jié)點(diǎn)試件進(jìn)行了低周往復(fù)荷載作用下的擬靜力試驗,分析各種節(jié)點(diǎn)的承載力、耗能性能、滯回特性等。試驗結(jié)果表明:各試件均發(fā)生了梁端塑性鉸破壞;與普通型鋼混凝土梁柱節(jié)點(diǎn)相比,核心區(qū)采用U形拉結(jié)筋的節(jié)點(diǎn)的承載力、延性及耗能性能基本相同,而梁端型鋼腹板開矩形孔的節(jié)點(diǎn)則降低較多。

Abstract:In order to solve the problems of the construction difficulty and complex structural details in steel reinforced concrete beamcolumn joints, two new types of steel reinforced concrete beamcolumn joints were proposed with Ushaped bars in joint core area and rectangular hole at beam end web respectively which were convenient for construction with simple structural details. In order to investigate differences of the seismic behaviors of the steel reinforced concrete beamcolumn joint and common steel reinforced concrete beamcolumn joint, the pseudostatic tests under low cyclic loading were carried out on nine specimens of three different types to study the loading capacity, energy dissipation capacity, and hysteretic characteristics. The results show that the plastic hinge failures appear at beam ends of all specimens. Compared with the common steel reinforced concrete beamcolumn joint, the bearing capacity, ductility and energy dissipation capacity of steel reinforced concrete beamcolumn joint using Ushaped bars in joint core area are almost the same, but steel reinforced concrete beamcolumn joint with rectangular hole at beam end web experiences a significant decrease in the  above properties.

Keywords:steel reinforced concrete; beamcolumn joint; Ushaped bar; beam end web with rectangular hole; seismic behavior
