【摘要】 通过对附加阻尼器的预应力装配式框架节点和现浇钢筋混凝土框架节点进行低周往复荷载试验,研究了现浇钢筋混凝土框架节点和附加阻尼器的预应力装配式框架节点的裂缝发展、破坏形态、滞回曲线及位移延性等抗震性能。试验表明:附加阻尼器的预应力装配式框架节点具有可观的耗能能力、较强的变形恢复能力和较好的位移延性,整体抗震性能良好,在抗震设防地区具有良好的应用前景。更多还原

【Abstract】 Based on low cyclic loading tests on the node of the prestressed assembly frame with additional dampers and the cast-in-situ reinforced concrete frame,seismic performances of two frames were studied including crack distribution,failure pattern,hysteresis curve and displacement ductility. The results show that the node of the prestressed assembly frame,which has good seismic dissipation ability,deformation recovery ability and good displacement ductility. The integrated structure has good seismic performance and can be popularized and applied in seismic precautionary zones.更多还原
