Title:
CONSTRUCTION METHOD FOR IMPROVING EARTHQUAKE RESISTANCE OF EXISTING SLUICE GATE PILLARS PROVIDED TO DAM, AND EARTHQUAKE-PROOF BRIDGE FOR DAM
Document Type and Number:
WIPO Patent Application WO/2011/059072
Kind Code:
A1
Abstract:
Existing sluice gate pillars (31-35) are structures which are located on both sides of gates (G1, G2), and support an existing operational bridge (40) which comprises steel main beams (50A, 50B) and the gates (G1, G2). Disclosed is a method for improving the earthquake resistance of the existing sluice gate pillars (31-35) provided to a dam. This method includes a process wherein, in all spans of the existing operational bridge (40), those ends of the main beams (50A, 50B) at which movable bearing structures are located, are connected, by means of high damping dampers (70) having high first-order rigidity hysteresis characteristics, to the tops of those existing sluice gate pillars (31-35) at which the movable bearing structures are located; and a process wherein the yield load value of the aforementioned high damping dampers at a seismic velocity is set to a value higher than a maximum seismic force generated by a large-scale earthquake in the bridge axis direction of the high damping dampers. The aforementioned maximum seismic force generated by the large-scale earthquake in the bridge axis direction of the high damping dampers is received in regions of high first-order rigidity prior to a stage where the hysteresis damping characteristics of the high damping dampers come into play.
