通过对附加阻尼器的预应力装配式框架结构节点和现浇框架节点的低周反复荷载试验,研究了钢筋混凝土框架结构和附加阻尼器的预应力装配式框架结构节点的裂缝分布、破坏形态、滞回曲线及位移延性等抗震性能。试验结果表明:附加阻尼器的预应力装配式框架结构抗震性能良好,在抗震设防地区具有良好的应用前景。
Through the low-cycle repeated loading tests of prestressed fabricated frame structure joints and cast-in-place frame joints with additional dampers, the crack distribution and failure modes of prestressed fabricated frame structure joints of reinforced concrete frame structure and additional damper are studied. Hysteresis curve and displacement ductility and other seismic performance. The experimental results show that the prestressed fabricated frame with additional damper has good seismic performance and good application prospect in the fortified area.
