Combined damper
The invention discloses a combined damper which comprises a damper body, the damper body comprises an upper steel plate, a lower steel plate and a combined damping mechanism, the combined damping mechanism is installed between the upper steel plate and the lower steel plate, the combined damping mechanism comprises a shape memory alloy outer ring and a soft steel inner ring, and the soft steel inner ring is installed in the shape memory alloy outer ring. After a local earthquake, a bridge body and a bridge generate horizontal displacement, a shape memory alloy outer ring and a soft steel inner ring are arranged, the soft steel inner ring is arranged in the shape memory alloy outer ring in a matched mode, plastic deformation of the soft steel inner ring can cause residual displacement of a structure, and then the post-earthquake function and post-earthquake recovery of the structure are affected. Residual deformation of the soft steel inner ring under the action of a strong earthquake can be limited through the shape memory alloy outer ring, the self-resetting capacity and the structural anti-seismic toughness of the damper are improved, earthquake energy can be dissipated in a graded mode, the self-resetting function is provided, therefore, horizontal displacement of a bridge structure is limited, and the earthquake resisting capacity of the bridge structure is improved.
本发明公开了一种组合式阻尼器，包括：阻尼器主体，该阻尼器主体包括上钢板、下钢板、组合阻尼机构，组合阻尼机构则安装在上钢板、下钢板之间，该组合阻尼机构包括形状记忆合金外圈、软钢内圈，而软钢内圈则安装在形状记忆合金外圈内的，当地震后使得桥体与桥梁发生水平位移，形状记忆合金外圈、软钢内圈的设置，在形状记忆合金外圈内配设软钢内圈，软钢内圈其自身的塑性变形可能会导致结构的残余位移，进而影响结构震后功能和震后恢复，通过形状记忆合金外圈可限制软钢内圈在强震作用下的残余变形，提升阻尼器自复位能力和结构抗震韧性，本发明可分级耗散地震能量并提供自复位功能，从而限制桥梁结构水平向位移，提高桥梁结构抵抗地震的能力。
