联机结构实验的子结构技术及应用

本文讨论了联机结构实验中采用子结构技术的算法和应用问题，通过对框架结构的实际实验应用得到如下结论：（１）采用子结构技术使联机结构实验方法的应用领域进一步拓广；（２）在整体结构中取出一部分进行实验，其余部分计算机模拟，最终的实验结果可以反应整体结构的各项性能。

The Substructure Technique and Ii's Application In On-Line Structure Test

The theory and application of on-line Structure tacting with substructuretechnique is discussed.The testing results of frame structures show that:(1)Substructuretechniques enlarge the application field of on -line structure teSting;(2)Although a part ofstructure was t6sted,and the rest part of the structure was analized by computer, nevertheless,the testing results can be used to simulate the behavior of the whole Structure duringearthquake.
