Performance of Rocking Systems on Shallow Improved Sand: Shaking Table Testing
Recent studies have highlighted the potential benefits of inelastic foundation response during seismic shaking. According to an emerging seismic design scheme, termed rocking isolation, the foundation is intentionally under-designed to promote rocking and limit the inertia transmitted to the structure. Such reversal of capacity design may improve the seismic performance, drastically increasing ...
متن کاملShaking a Box of Sand
– We present a simple model of a vibrated box of sand, and discuss its dynamics in terms of two parameters reflecting static and dynamic disorder respectively. The fluidised, intermediate and frozen (‘glassy’) dynamical regimes are extensively probed by analysing the response of the packing fraction to steady, as well as cyclic, shaking, and indicators of the onset of glassy behaviour are analy...
متن کاملTHE SHAKING TABLE CONCENTRATOR: INFLUENCE OF TABLE PARAMETERS ON MANGANESE CONCENTRATION
Abstract: point of view. In this study, a shaking-table was used for concentrating a manganese ore sample from the Ghasem Abadarea in Kerman, Iran. Experiments were designed by using LThe influence of each variable and their interactions on the operation of the device was studied. The variables underinvestigation were: table slope, table frequency, water flowrate, feed rate, and particle size. ...
متن کاملBidirectional Shaking Table Tests of a One-fourth Scale Reinforced Concrete Space Frame
Shaking table tests on the 1/4th-scale three-story reinforced concrete frames were carried out to investigate the effects of bidirectional earthquake motions on overall nonlinear response of reinforced concrete frame buildings. Two identical models were constructed and one was subjected to bidirectional horizontal earthquake motions and the other was subjected to unidirectional one. A series of...
متن کاملAn Expert System for Shaking Table Diagnostics
An expert system, for fault diagnosis of shaking table operations, is presented. The system is designed as one element of an integrated, computer-based method for plant enhancement, for application in the mineral processing industry. The relationship between expert and conventional software techniques is discussed. The system is based on prod uc tion rule s and has been wri tten in the PROLOGla...
