Instructional shake table for demonstrations in structural dynamics
Instructional Shake tables are an effective pedagogical tool for use in class room and lab, for teaching structural dynamics at advanced undergraduate and graduate level. A detailed study is carried out for a miniature shake table, currently used by the University Consortium of Instructional Shake …

Scale Model Shake Table Testing of Shallow Embedded Foundations in Soft Clay
<p>This research involves shake table testing of 1g scale models that mimic the coupled seismic response of a structure on a shallow mat foundation and foundation soil (known as soil-foundation-structural-interaction or SFSI). In previous research, SFSI effects have been quantified through …

Experimental Investigation into the Long-Term Seismic Performance of Dry Storage Casks
A series of eight shake table experiments were conducted to assess the long-term seismic performance of Dry Storage Casks (DSCs). Four scaled specimens were designed to cover a wide range of commercially available DSCs with emphasis on aspect ratios, the radius over the height of the center of mass …

Fatigue of Masonry Walls with CFRP Applied Externally for Out-of-Plane Loads
… in this thesis. With the use of an oscillating shake table to generate the out-of-plane loading, the walls were fixed at the base and cantilevered from the shake table. By determining the frequency and amplitude that generated the cracking moment in the baseline unreinforced wall, the remaining …

Preliminary investigation of the vibration characteristics of a slip table
The problem of analyzing a shake table is simplified to that of a bar of constant cross section with a weight attached at any point along the bar, all subjected to a sinuaoidal force at one end of the bar. The bar, suspended by wires, represents the table. The weight used in the experiment …
