Multi-stage buffering inhaul cable damping support
The invention relates to a multi-stage buffering inhaul cable damping support which comprises an upper cover plate, an upper seat plate, a support body, a lower seat plate, a lower cover plate, anchor bolts, SMA inhaul cables, CFRP inhaul cables and inhaul cable hole channels. The SMA inhaul cable and the CFRP inhaul cable penetrate through reserved inhaul cable hole channels in the upper base plate and the lower base plate of the support, and the ends of the SMA inhaul cable and the ends of the CFRP inhaul cable are connected through connectors to form a closed ring shape. The free path of the SMA inhaul cable is smaller than that of the CFRP inhaul cable, when the earthquake vibration intensity is small, the two inhaul cables do not work, and the inertia force of the upper structure is transmitted only through the support body; when the earthquake vibration intensity reaches medium, the SMA inhaul cable begins to work, dissipates part of energy and inhibits rapid growth of bridge earthquake response; when strong impact occurs, the SMA inhaul cable and the CFRP inhaul cable play a role at the same time, and the excessive displacement of the pier beam is limited. After an earthquake, the support can achieve self-resetting under the action of the superelastic SMA inhaul cable, and residual displacement is reduced. The support meets the damping requirement of a near-fault area, and is convenient to install, small in residual displacement and suitable for application and popularization.
本发明涉及一种多级缓冲拉索减震支座，包括上盖板、上座板、支座主体、下座板、下盖板、锚固螺栓、SMA拉索、CFRP拉索、拉索孔道。SMA拉索和CFRP拉索穿过支座上座板和下座板中的预留拉索孔道，端部以接头相连形成闭合的环状。SMA拉索的自由程要小于CFRP拉索，地震振动强度较小时两种拉索都不工作，仅靠支座主体传递上部结构的惯性力；当地震振动强度达到中等时，SMA拉索开始工作，并耗散部分能量，抑制桥梁地震响应的快速增长；当强冲击发生后，SMA拉索和CFRP拉索同时发挥作用，限制墩梁过大位移。震后在超弹性SMA拉索的作用下支座可实现自复位，减少残余位移。本发明支座适用于近断层区域的减震要求，安装方便，残余位移小，适合推广和应用。
