Frame type pier transverse anti-seismic structure

Abstract

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.

Description

technical field [0001] The invention relates to bridges, in particular to a frame-type bridge pier transverse seismic structure. Background technique [0002] In recent years, my country's frequent earthquakes have brought huge economic losses to human beings. After the Wenchuan Earthquake, people's attention has gradually been paid to the earthquake resistance of bridges. The longitudinal anti-seismic performance of bridges is weaker than that of the horizontal ones. Therefore, there are many researches on the longitudinal anti-seismic properties of bridges, and many anti-seismic devices have been developed. Under the large lateral displacement. [0003] The existing anti-seismic damping design at home and abroad is mostly aimed at the longitudinal seismic action of the bridge, but not the lateral seismic action of the bridge. In the transverse direction, there are only some structural treatments, and there is no special shock-absorbing and energy-absorbing device, so it c...

[0003] The existing anti-seismic damping design at home and abroad is mostly aimed at the longitudinal seismic action of the bridge, but not the lateral seismic action of the bridge. In the transverse direction, there are only some structural treatments, and there is no special shock-absorbing and energy-absorbing device, so it cannot be fundamentally reduced.
