Accordingly, this study aims to identify the behavior of early aged CPB 2.5 hrs. 4.0 hrs, and 10.0 hrs during seismic loading using shaking table tests. The results of this research show that CPB samples cured to 2.5 hrs are susceptible to liquefaction under the studied seismic loading conditions, while CPB samples cured to 4.0 and 10.0 hrs ...
Shaking table tests on the seismic response characteristics of a reinforced concrete RC structure before and after retrofitting were conducted at Xian University of Architecture and Technology. The shaking table with the dimension of 4 m length 4 m width in plane can produce threedimensional and six degreeoffreedom motions.
Nov 01, 2020 A series of shaking table tests were performed to investigate the seismic performance of a prefabricated corrugated steel utility tunnel. The utility tunnel model, two kinds of pipeline models, and three different bracket models were designed and assembled based on actual tunnels and the similitude relationship.
shaking tables with programmable characteristics have been ... So ideally by introducing into the system software-shaking table the seismic signal of some historical ground motions it is ... an important instrument to study the dynamic response of a structure.
A series of modeling tests are implemented on shaking table instrument to reflect the mechanism of soil structure interaction and examine the validity of method of uplifting underground structural seismic resistance through strengthening central columns.
Oct 26, 2016 Shaking Table. A computer controlled servo hydraulic uniaxial horizontal shaking table facility has been used in simulating horizontal seismic action, associated with seismic or any other vibration conditions. The shaking table has a loading platform of 1 m 1 m size and the payload capacity is 1 ton.
Seismic retrofit and shaking table test of medical equipment in a hospital J.-F. Chai amp F.-R. Lin National Center for Research on Earthquake Engineering, Taipei, Taiwan ABSTRACT Due to the variety in the categorization of nonstructural components and medical equipment in a hospital, before embarking on seismic design, the critical andor
The seismic behaviour of typical unreinforced masonry URM brick houses that were common in early last century in NZ, and still common in many developing countries, is experimentally investigated in this research. A one half-scale model house was constructed and tested under earthquake ground motions on a shaking table.
Taking a bedding rock slope with weak structural plane as the prototype, a shaking table test with a similarity ratio of 110 is designed and carried out. By analyzing the acceleration and displacement responses at different positions of the slope, the seismic response and instability mechanism of rock bedding slope under different seismic amplitudes, frequencies, and
In the E-Defense shaking table testing facility, Suzuki et al. 7 carried out a shaking table test with a cylindrical laminar shear soil box, and identified the factors affecting the pile stress distribution in the seismic process. Through shaking table tests with a centrifuge, Hussien et al. 8 observed the dynamic responses of single piles ...
The 14 scale model for shaking table test was designed as a typical three-storey-office building strengthened with external steel reinforcement mesh mortar layer. The process of modeling was provided, including the relationship of model and proto structure, and the design principle of model components. The scheme of shaking table test was determined,...
