| 摘 要： | 基于预应力与非预应力高性能混凝土震损框架的低周反复荷载试验，对其受力过程、破坏形态、滞回曲线、骨架曲线、恢复力模型、变形恢复能力、刚度退化、耗能能力等抗震性能进行较为深入的研究与分析。研究表明：高性能混凝土震损框架的抗震性能较震损前有明显的降低，但仍具有一定的抗震能力。

| Abstract: | Based on experiments of prestressed and non-prestressed HPC damaged frames under low reversed cyclic loading, failure pattern, hysteresis curves, skeleton curves, restoring force model, deformation restoring behaviors, rigidity degeneration and energy dissipation etc, are studied systematically. And studies show that HPC damaged frames have worse seismic performance than HPC frames, but can also behave with a certain extent of seismic performance. |

| Keywords: | HPC damaged frame prestressing seismic performance |
