Column base joint with additional grid type damper capable of being replaced after earthquake
The invention relates to a column base joint with an additional grid type damper capable of being replaced after an earthquake, and belongs to the technical field of structural engineering earthquake resistance. The column base joint with the additional grid type damper capable of being replaced after the earthquake comprises an upper column, a lower column, a bowl-shaped support positioned in an axial center of the upper column and the lower column and the grid type damper arranged around the bowl-shaped support. The end faces of an upper bowl-shaped support and a lower bowl-shaped support are provided with arc-shaped protrusions and arc-shaped grooves respectively, and a plurality of wave springs are additionally arranged between the arc-shaped protrusions and the arc-shaped grooves, or the peripheries of the bowl-shaped supports are sleeved with a plurality of disc springs. The grid type damper is a steel structural part and comprises frames and grids interwoven in the frames, and an upper frame and a lower frame are detachably connected with steel end plates of the upper column and the lower column respectively. According to the column base joint with the additional grid type damper capable of being replaced after the earthquake, force transmission is clear, the bowl-shaped support can bear axial force and shearing force, and rotation in all directions can be achieved during the earthquake. The grid type damper can dissipate earthquake energy, improves anti-seismic capacity, and is convenient to replace and maintain after the earthquake.
本发明涉及一种附加震后可更换的网格型阻尼器的柱脚节点，属于结构工程抗震技术领域，包括上下柱、位于上下柱轴向中心的碗状支座和围设在碗状支座四周的网格型阻尼器；上下两个碗状支座的端面分别具有弧形凸起和弧形凹槽，二者之间加设和多个波形弹簧，或者在碗状支座的外周套装多个碟簧；网格型阻尼器为钢结构件，包括边框和交织在边框内的网格，上下边框分别与上柱和下柱的钢端板可拆卸连接。传力明确，碗状支座可以承担轴力和剪力，地震时可以实现各个方向的转动。网格型阻尼器可以耗散地震能量，提高抗震能力，震后更换、维修方便。
