Maximizing Displacements From The Controlled Underground Expansion Technique

结构模型和足尺结构的试验对于了解结构在地震荷载作用下的行为是重要的。振动台试验、拟动力试验和静力试验等技术在过去曾被用于各种应用，并取得了一定程度的成功。这项研究项目将检验控制地下膨胀技术，将其用作将地震类型的地面运动诱导到模型结构中的设施。重点将放在实现地面位移达到10英寸。本研究结果可直接应用于结构动力学研究的现场实验装置的设计。

Experiments on structural models and full-scale structures are important to understanding the behavior of structures subjected to earthquake loadings. Techniques such as shake table experimentation, pseudo-dynamic experimentation, and static experimentation have been used in the past for various applications with some degree of success. This research project will examine the controlled underground expansion technique for use as a facility for inducing earthquake-type ground motion into model structures. Emphasis will be placed on achieving ground displacements up to 10 inches. The results of this research are directly applicable to the design of an in situ experimentation facility for use in structural dynamics research.
