［摘要］對薄柔鋼框架中的延伸端板式梁柱節(jié)點進行了試驗。將節(jié)點置于足尺薄柔鋼框架中進行加載測試，使節(jié)點的邊界條件和受力狀態(tài)符合實際結構狀況。從結構剛度和節(jié)點區(qū)變形兩方面對節(jié)點抗彎剛度和節(jié)點域剪切剛度進行了分析，結果表明薄柔鋼框架中的端板式節(jié)點在一定條件下可以滿足剛性連接的要求。

Abstract:Extended end plate joint for beamcolumn connection in slender steel frame was tested to learn the rigidity of joint, and the tested joint was put into full size frame model to simulate its boundary condition and structural behavior closely to working condition. By the structural stiffness and joint distortion research, the bending and shear stiffness of joints were analyzed. The results show that for slender steel frames, the extended end plate joint can be considered as rigid connection in limited conditions.
Keywords:stiffness; slender steel frame; extended end plate connection; panel zone
