Large-span arch bridge grading damping mechanism and grading damping method
The large-span arch bridge graded damping mechanism is used for being detachably installed between a main beam and a pier, a support is installed between the main beam and the pier, so that a gap is formed between the main beam and the pier, and the large-span arch bridge graded damping mechanism is located in the gap. Two ends are detachably mounted at the bottom of the main beam and the top of the pier respectively; the large-span arch bridge grading damping mechanism comprises a damper and a damping material, and the damping material is placed in a container; the container is of a barrel-shaped structure with an opening in one end, and correspondingly, the opening faces the top of a pier or the bottom of a girder; the damper and the container are oppositely arranged, and one end of the damper is correspondingly and detachably mounted at the top of the pier or the bottom of the main beam; the other end of the damper extends into the damping material through the opening; according to the large-span arch bridge grading damping mechanism, the three-level damping energy dissipation function can be achieved, the damping mechanism can be easily repaired after a small earthquake and can be repeatedly used, and the damping mechanism is easy to disassemble and replace after a large earthquake, simple in structure and easy and convenient to install.
本发明公开了一种大跨拱桥分级减震机构及分级减震方法，用于可拆卸的安装于主梁和桥墩之间，主梁和桥墩之间安装有支座，使得主梁和桥墩之间具有间隙，大跨拱桥分级减震机构位于间隙中，且两端分别可拆卸安装于主梁底部和桥墩顶部；大跨拱桥分级减震机构包括阻尼器和阻尼材料，阻尼材料放置于容器中；容器为一端具有开口的桶状结构，对应的，开口朝向桥墩顶部或主梁底部；阻尼器与容器对置设置，且阻尼器的一端对应可拆卸安装于桥墩顶部或主梁底部；阻尼器的另一端通过开口伸入阻尼材料中；本发明公开的大跨拱桥分级减震机构能够实现三级减震耗能的功能，能够实现小震后减震机构易于修复且可重复使用，大震后减震机构易于拆卸和更换，结构简单、安装简便。
