Frame type pier transverse anti-seismic structure
The invention discloses a transverse anti-seismic structure of a frame type bridge pier, which is used for remarkably improving the transverse anti-seismic performance of the frame type bridge pier and is convenient to construct. The structure is composed of a pier cover beam, a left side pier column and a right side pier column, wherein a single-rod bidirectional viscous damper is fixedly arranged on the lower edge of the middle span of the pier cover beam, and the axis of a piston rod of the single-rod bidirectional viscous damper extends in the longitudinal direction of the pier cover beam.Inhaul cable steering devices are vertically arranged on the left side pier column and the right side pier column at intervals, and inhaul cable fixing devices are fixed to the lower ends of the inhaul cable steering devices. The two ends of the piston rod are connected with a left inhaul cable and a right inhaul cable respectively, the left inhaul cable and the right inhaul cable are crossed between the left pier stud and the right pier stud through the corresponding inhaul cable steering devices, and the lower ends of the left inhaul cable and the right inhaul cable are connected to the inhaul cable fixing devices.
一种框架式桥墩横向抗震构造，以显著提高框架式桥墩的横向抗震性能，且施工方便。包括由桥墩盖梁和左侧桥墩墩柱、右侧桥墩墩柱构成的框架式桥墩，所述桥墩盖梁跨中下缘上固定设置单杆双向式粘滞阻尼器，该单杆双向式粘滞阻尼器的活塞杆的轴线沿桥墩盖梁的纵向延伸。所述左侧桥墩墩柱、右侧桥墩墩柱上竖向间隔设置拉索转向装置，且在其下端固定拉索固定装置。所述活塞杆的两端分别连接左侧拉索、右侧拉索，左侧拉索、右侧拉索经过对应的拉索转向装置在左侧桥墩墩柱、右侧桥墩墩柱之间形成交叉，其下端连接在拉索固定装置上。
