Development of Low-friction Factor Sliding Isolation Device
Sliding bearings with low coefficient of friction enable the base isolation system with longer natural period than previous ones and to be effective even for small to medium earthquakes. This paper introduces the sliding bearings with low coefficient of friction, which is almost under 0.03. It is shown that newly developed materials for the sliding bearings contribute to reduce coefficient of f...
متن کاملControl of structures with friction controllable sliding isolation bearings
A friction controllable sliding isolation system was developed and experimentally and analytically investigated by Feng et al. (Feng, Q., Shinozuka, M. & Fujii, S. A. friction controllable sliding isolation system. J. Eng. Mech., ASCE, 1993, 119(6), in press), the control algorithm having been developed based on a key assumption that the structural motion is always in the sliding phase. However...
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 کاملOn the Optimum Placement of Dissipators in a Steel Model Building Subjected to Shaking-Table Tests
The following research presents the numerical and experimental results obtained on a reduced scale steel model of a medium-rise building structure dynamically protected with energy dissipaters. The steel-steel friction dissipates energy as the structure undergoes interstory drifts. A preliminary numerical analysis is performed to determine the best position of the friction dampers in the longit...
