摘　　要：近年来,随着全球气候变化的加剧和地壳运动的频繁,地震灾害频发。无黏结预应力混凝土剪力墙由于具有良好的抗震效果,被广泛用于工程抗震中,然而在面对强震的情况下,这种结构的墙脚部位极易损坏,使构件产生不可逆的损伤灾害,且由于预应力筋长度限制使它难以适用于高层建筑。为解决这一问题,众多学者提出内置碟簧自复位混凝土剪力墙,并在近年来得到广泛的研究,文中重点针对内置碟簧自复位混凝土剪力墙的发展进程进行详细的研究,总结分析不同内置碟簧自复位混凝土剪力墙的结构组成、工作机理以及抗震性能,并基于此提出内置碟簧自复位混凝土剪力墙当前存在的问题及未来的发展方向。In recent years,with the intensification of global climate change and frequent tectonic movements,earthquake disasters have become more prevalent.Unbonded prestressed concrete shear walls are widely used in engineering seismic resistance due to their excellent seismic performance.However,in the case of strong earthquakes,the wall's base is highly susceptible to damage,leading to irreversible structural damage.Moreover,the length limitation of the prestressing tendons makes these structures difficult to apply in high-rise buildings.To address this issue,many scholars have proposed the use of built-in disc spring self-resetting concrete shear walls,which have been extensively researched in recent years.This paper focuses on the development process of built-in disc spring self-resetting concrete shear walls,summarizing and analyzing their structural composition,working mechanism,and seismic performance.Based on this,the paper also highlights the current challenges of this technology and proposes directions for future development.
