A series of large-scale shaking table tests is conducted for a high-rise building structure subjected to long-period ground motions. A test method is developed to preserve the original dimensions of structural members of a prototype building that has 21 stories with a total height of 80 m.
Shaking Table Foundations. It is a comparatively simple matter to build foundations substantial enough so that they will not have a tendency to shake or vibrate as a result of the motion of the tables. A reinforced-concrete slab need not be more than 6 or 7 in. thick to provide a perfectly rigid foundation, even at a considerable height above ...
Shaking table separation is the gravity concentration process in which the combined action of the asymmetric reciprocating motion of the table and the water flow on the thin inclined layer separates the mineral particles according to their densities on a wide inclined table. Shaking table separation is suitable for separation of fine particle ...
These relations can be used as guidelines in planning of future seismic tests on the UCSD-NEES shake table or on large shake tables with similar controllers. The third objective is to evaluate the effectiveness of the existing iterative correction/tuning procedure for the UCSD-NEES shake table.
In order to study the seismic performance of corroded steel frame structures under the acidic atmosphere environment, two five-layer steel frame structures (S1, S2)with different corrosion ratios were designed. The test of S2 was implemented accelerated corrosion by aerosol corrosion box (S1 as the contrast test with no corrosion), and then shaking …
UC's shake table will be the largest outdoor shaking table and the second largest in the world after Japan's indoor E-Defense table. It's a pretty impressive feat and you can live stream the construction process along the way. It's not much to look at now, but closer to the October 2021 launch, it certainly will be.
These tables allow manufacturers to portion out delicate food items like chips or candy. With integrated sensors, a vibration table can assess when a portion has reached the right weight and then shake the product into the packaging. Food and beverage operations can also use vibration tables to remove air bubbles from products like chocolate.
