The invention discloses a prefabricated assembly type self-resetting frame integral structure which comprises foundations, steel columns, cross beams, floor slabs, prefabricated filling wallboards andU-shaped clamps. The steel columns and the foundations form self-resetting column base structures; the steel columns and the cross beams connected with two sides thereof form self-resetting joint structures; when an earthquake comes, the self-resetting joint structures located at the beam-column joints dissipate earthquake energy firstly, and the horizontal bearing capacity of the structure is improved; secondly, the floor slabs and the prefabricated filling wallboards are not in direct contact with the steel columns; certain distances are reserved between the prefabricated filling wallboardsand the bottoms of the U-shaped clamps on the upper portion and the two sides, when the overall structure has the tendency of lateral overturning, the floor slabs and the prefabricated filling wallboards keep a normal stable state, it is guaranteed that the gravity center of the overall structure does not deviate substantially along with the earthquake action, and the overall structure has the self-resetting capacity after an earthquake. And finally, the self-resetting joint structures and the self-resetting column base structures play a role to jointly ensure that joints and column bases arenot greatly damaged, so that the energy consumption and the self-resetting function of the structure are realized.
本发明公开了一种预制装配式自复位框架整体结构，包括基础、钢柱、横梁、楼板、预制填充墙板和U型卡；钢柱与基础形成自复位柱脚结构；横梁与其两侧连接的横梁形成自复位节点结构；当地震来临时，位于梁柱节点的自复位节点结构首先耗散地震能量，提高结构的水平承载力；其次因为楼板和预制填充墙板不与钢柱直接接触，且预制填充墙板与上部和两侧的U型卡底部留有一定间距，当整体结构有侧向倾覆的趋势时，楼板和预制填充墙板保持正常的稳定状态，保证整体结构的重心不随地震作用而大幅偏移，且使得整体结构在震后有自复位的能力；最后，自复位节点结构和自复位柱脚结构发挥作用，共同确保节点和柱脚不受太大的损伤，实现结构的耗能与自复位功能。
