[摘要] 為研究端板豎放門(mén)式剛架輕型房屋鋼結(jié)構(gòu)抗震性能，對(duì)3個(gè)半榀比例為1/2且端板豎放門(mén)式剛架試件進(jìn)行水平循環(huán)荷載試驗(yàn)研究，分析了端板厚度，螺栓直徑，螺栓排布等因素對(duì)節(jié)點(diǎn)承載力、轉(zhuǎn)動(dòng)剛度、轉(zhuǎn)動(dòng)能力和極限破壞狀態(tài)的影響和門(mén)式剛架在水平循環(huán)荷載作用下的滯回性能。試驗(yàn)結(jié)果表明端板豎放節(jié)點(diǎn)的門(mén)式鋼架耗能不好，滯回曲線不飽滿，并且其破壞模式不同于一般鋼框架，端板厚度，螺栓直徑，螺栓排布等因素對(duì)門(mén)式鋼架滯回性能影響很小。

Abstract: Horizontal Cyclic loading test of 3 half-scale vertical end-plate connections of single storey factory building were carried to investigate their seismic behavior. The influences of end-plate thickness, bolt diameter, bolt numbers on the loading-carrying capacity, rotational stiffness, rotational capacity, ductility, ultimate failure modes and energy dissipation have been analyzed. These speciment showed not well hysteretic behavior and energy dissipation under cyclic loads. what's more the load- displacement curve is not full, and then the ultimate failure modes is different from steel frame, at last there is a little influences of end-plate thickness, bolt diameter, bolt number on the behavior of ductility and energy dissipation.
