本文对拟动力试验模拟结构地震反应的能力进行了研究。首先，介绍了改进PSD测试中位移控制的算法。其次，用一个两层钢框架结构模型检验了振动台试验和PSD试验之间的相关性。结果发现，整体相关性是好的，但恢复力是在振动台试验比PSD试验中更大。补充试验证实，加载速率的影响是恢复力差异的原因。第三，实验误差行为进行了检查的基础上，弹性PSD测试应用于全尺寸六层钢结构。分析了位移误差对PSD响应的影响，指出位移误差是PSD响应中产生高阶模态振动的主要原因，并研究了位移误差的特性及其对PSD响应的影响。
This paper presents investigations into the capacity of the pseudo-dynamic (PSD) test to simulate the earthquake response of structures. First, algorithms developed for improving the displacement control in the PSD test are introduced. Second, the correlation between shake table and PSD tests is examined using a two story steel frame. It is found that the overall correlation is good, but that the restoring force is larger in the shake table test than in the PSD test. A supplemental test verified that the effect of loading rate is responsible for the difference in the restoring force. Third, experimental error behavior is examined based on an elastic PSD test applied to the full-scale six story steel structure. The displacement error is found to be the major source that promotes higher mode vibration in the PSD response, and characteristics of the displacement error as well as its effects on the PSD response are investigated.
