Shaking Table Tests on a Passive Equipment Isolation System for Earthquake Protection

Volume 8: Seismic Engineering, 2009
The present work refers to steel frame structures in industrial plants. A passive isolation system for seismic protection of a considerable equipment, already present on a frame support structure and rigidly constrained to it, is investigated through both numerical simulations (1+1 DOF system) and shaking table tests on a 1:5 scale two-story steel ...

Shake Table Testing: The Most Reliable Tool to Simulate Earthquakes

2017
Recent earthquakes have shown the vulnerability of our current infrastructure, as previous building standards have not been adequate to counter natural forces effectively. Shake tables are the most reliable testing method for evaluating seismic performance of structural models. In shake table testing, ground motion records from previous earthquakes can

Shake Table Response of RC Bridge Piers to Near-Fault Earthquake

IABSE Reports, 2009
<p>Near fault ground motion (NFGM) is a single long period velocity pulse of large magnitude. These earthquakes have caused severe and impulsive damage on various infrastructures because the epicentre is close to the urban area. These characteristics are unique compared to the far-fault ground motion (FFGM), upon which nearly all seismic design ...

NONLINEAR SHAKE TABLE IDENTIFICATION AND CONTROL FOR NEAR-FIELD EARTHQUAKE TESTING

Journal of Earthquake Engineering, 2005
The primary focus of a structural shake table system is the accurate reproduction of acceleration records for testing. However, many systems deliver variable and less than optimal performance, particularly when reproducing large near-field seismic events that require extreme table performance.

Oscillation Response of Museum Cultural Relics under Earthquake by Shaking Table Tests

Applied Mechanics and Materials, 2011
To protect movable cultural relics,by shaking table tests oscillation responses of museum free-standing cultural relics under earthquakes were studied.Based on actual sizes of a museum showcase,a 1:1 scale model was built whose bottom was fixed on the shaking table.A bronze cultural relic was put in the showcase by free-standing mode.By white noise ...

Design of Earthquake Shaking Table (EST) Using Ball Screw Guide Linear Actuator

2019 International Conference on Advanced Mechatronics, Intelligent Manufacture and Industrial Automation (ICAMIMIA), 2019
Earthquake shaking table is one of the tools used to simulate earthquake behavior and its effect for the structures. This research describes a process of designing a dual-axis shaking table using ball screw linear guide actuator as its main actuator. The system utilizes Bressenham algorithm for controlling both actuators synchronously.

Optical motion tracking in earthquake-simulation shake table testing: Preliminary results

2009 Conference Record of the Forty-Third Asilomar Conference on Signals, Systems and Computers, 2009
Sensors such accelerometers and displacement transducers are generally used in earthquake-simulation shake table testing to measure the induced motions. In particular the Anti-seismic Structure Laboratory at the Pontificia Universidad Catolica del Peru (PUCP) uses LVDT (linear variable differential transformer) sensors, which can achieve accurate ...

Shaking table test of utility tunnel under non-uniform earthquake wave excitation

Soil Dynamics and Earthquake Engineering, 2010
Abstract A series of shaking table tests were conducted on scaled utility tunnel models with and without construction joints under non-uniform input earthquake wave excitation. Details of experimental setup are first presented with particular focuses on: design and fabrication of double-axis laminar shear box with a rectangular hole opened on its ...
