Maximizing Displacements From The Controlled Underground Expansion Technique

点击翻译按钮获取中文摘要

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.
