Subway station laminated core column capable of being rapidly repaired after earthquake
The invention discloses a subway station laminated cored column capable of being rapidly repaired after an earthquake. The subway station laminated cored column comprises a core column, a detachable prefabricated hollow column section, an overall prefabricated hollow column section and a friction layer. The prefabricated hollow column section is vertically overlapped on the outer side of the core column, and the prefabricated hollow column section and the core column are mutually matched to coordinate deformation. When the structure generates horizontal interlayer deformation under the earthquake effect, the core column is bent and deformed within the deformation capacity range, the laminated column sections generate relative dislocation and bear less shearing force and bending moment, and the typical damage mode of the laminated column and the core column is local compression damage of the prefabricated hollow column sections at the two ends. According to the subway station laminated cored column capable of being rapidly repaired after the earthquake, the deformability of an anti-seismic key stand column of an underground structure is improved, meanwhile, the detachable prefabricated hollow column sections with the two ends prone to damage can be simply replaced, and it is guaranteed that the subway station structure has the capacity of rapidly recovering the function after the earthquake; and the anti-seismic toughness of urban lifeline engineering is further improved.
本发明公开了一种震后可快速修复的地铁车站叠层加芯柱，包括芯柱、可拆卸预制空心柱段、整体预制空心柱段和摩擦层。预制空心柱段竖向叠加在芯柱外侧，两者相互配合，协调变形。当结构在地震作用下产生水平层间变形时，芯柱在变形能力范围内发生弯曲变形，叠层柱段之间发生相对错动而较少承担剪力和弯矩，叠层加芯柱的典型破坏模式为两端预制空心柱段的局部受压破坏。本发明一种震后可快速修复的地铁车站叠层加芯柱在提高地下结构抗震关键立柱的变形能力的同时，能够实现两端易发生破坏的可拆卸预制空心柱段的简单替换，保证地铁车站结构具备震后功能可快速恢复的能力，进而提升城市生命线工程的抗震韧性。
