Shake Table Test of Long Span Cable-Stayed Bridge Subjected to Near-Fault Ground Motions Considering Velocity Pulse Effect and Non-Uniform Excitation

Applied Sciences, 2020
This paper presents the results of shake table tests of a scaled long span cable-stayed bridge (CSB). The design principles of the scaled CSB are first introduced. The first six in-plane modes are then identified by the stochastic subspace identification

SHAKING TABLE TEST ON REINFORCED SAND

Proceedings of geotextile symposium, 1987
Shaking table tests were conducted on saturated sand layer reinforced with wires in order to apply reinforced earth method to liquefaction countermeasure method.In this paper, the effects of placing direction, reinforcing range and stiffness of reinforced materials on the liquefaction resistance are investigated. Shown below are results of this tests.i)

Shake table tests of different seismic isolation systems on a large scale structure subjected to low to moderate earthquakes

Journal of Traffic and Transportation Engineering (English ed. Online), 2018
Seismic isolation systems designed for extreme events may likely experience low to moderate earthquakes during the design life of the structure rather than the extreme event itself.

Artic Determination of Dynamic Characteristics the Structure with ARX and ARMAX Estimation Methods

Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2020
In this study, the dynamic behavior of a single-span four-storey steel model structure is tried to determine by using 2 different methods. Connections between beams and columns are produced as rigid and the structure is connected to the shake table by a ...
