Embodiment Construction
[0018] Such as figure 1 and figure 2 The shown seismic-isolation bridge structure system containing buckling-constrained braces and seismic-isolation rubber bearings includes: pier 1, cover girder 2 fixed above pier 1, and main girder 3 on the upper end of cover girder 2; pier 1 is The double-column bent pier is composed of double-column bent pier, cover beam 2 and the ground, and the buckling constraint support 4 is installed in the diagonal direction, that is, the inclination direction of the fixed end connection line of the buckling constraint support 4 is the same as that of the double-column bent frame pier, The cover beam 2 and the ground form a rectangle with the same diagonal direction; the contact end surface of the cover beam 2 and the main beam 3 is provided with a vibration-isolation rubber bearing 5;
[0019] Adopt the above-mentioned structural system through the buckling constrained support 4 and the seismic isolation rubber bearing 5 to realize the improvemen...
