［摘要］采用新型單邊全螺栓連接的方形鋼管柱與H型鋼梁節(jié)點具有抗震性能好、安裝方便的優(yōu)點。設(shè)計兩個節(jié)點試件：采用普通全螺栓連接的H型鋼柱與H型鋼梁節(jié)點及采用新型單邊全螺栓連接的H型鋼柱與H型鋼梁節(jié)點。通過對兩組試件進行低周反復(fù)試驗，對比研究新型單邊全螺栓節(jié)點與普通全螺栓節(jié)點的破壞形態(tài)以及承載力、滯回性能、延性、耗能能力、剛度退化等抗震性能的異同，結(jié)果表明：兩組試件在破壞形態(tài)以及以上所有抗震性能方面基本接近，說明采用本課題組提出的新型單邊全螺栓連接在研究方面可采用普通全螺栓連接的相關(guān)方法和理論。

Abstract:The joint of square steel tube column and H-typed steel beam with the new type of unilateral all-bolt connection has the advantages of good seismic performance and convenient installation. Two joints were designed, including the joint of H-typed steel column and H-typed steel beam with ordinary all-bolt connection, and the joint of H-typed steel column and H-typed steel beam with new type of unilateral all-bolt connection. Low cyclic loading tests were conducted on the two specimens to compare the similarities and differences of performances of the joint with ordinary all-bolt connection and the joint with new type of unilateral all-bolt connection, including failure mode, bearing capacity, hysteretic behavior, ductility, energy dissipation and stiffness degeneration. The results show that two groups of specimens have the basically close performances in failure mode and all of the above seismic performances. It indicates that the research on proposed new type of unilateral all-bolt connection can adopt related method and theory for ordinary all-bolt connection.
Keywords:H-shaped steel; new type of unilateral all-bolt connection; failure mode; seismic performance
