ABSTRACT

The earthquake resilience of low-damage self-centering precast concrete frame connections (LDSCPC) is studied in this article. Cyclic load tests are carried out, and the results show that the overall damage of the precast beam of specimen LDSCPC1 at 3% drift is even less than that of specimen RC1 at 0.25% drift. The LDSCPC connections can still maintain the original performance to a large extent after the earthquake and almost wholly recover to the initial performance level after replacing the dampers. Based on maintaining similar bearing capacity and deformation ability with RC joint, LDSCPC connections have excellent earthquake resilience.

低损伤自定心预制混凝土框架连接抗震试验研究

摘要

本文研究了低损伤自定心预制混凝土框架连接（LDSCPC）的抗震性能。进行了循环荷载试验，结果表明，试件LDSCPC1预制梁在3%位移时的整体损伤甚至小于RC1试件在0.25%位移时的整体损伤。LDSCPC连接在地震后仍能在很大程度上保持原有性能，更换阻尼器后几乎完全恢复到初始性能水平。LDSCPC连接在保持与RC节点相似的承载能力和变形能力的基础上，具有出色的抗震能力。
