Shake table testing of unbonded post-tensioned concrete walls with and without additional energy dissipation

Soil Dynamics and Earthquake Engineering, 2019
Recently an innovative unbonded Post-Tensioned (PT) concrete wall system was developed that consists of a Precast Wall with End Columns (PreWEC). Dynamic testing was conducted to better understand the seismic response of PreWEC systems and to provide ...

Improvements for seismometers testing on shake table

2019 14th IEEE International Conference on Electronic Measurement & Instruments (ICEMI), 2019
This study aims to design fixtures used on the horizontal and vertical shake tables to improve measuring accuracy for the seismometer under test. Based on ANSYS, the model analysis is applied with finite element method. After multiple calculations and calibrations, optimization models are finalized, and then material objects are manufactured basing on ...

Scaled shaking table testing of higher‐mode effects on the seismic response of tall and slender structures

Earthquake Engineering & Structural Dynamics, 2022
As structures are built taller and more slender, their response becomes increasingly sensitive to dynamic loads that are induced by the buildings’ higher‐frequency vibration modes.

Shake table testing of an open rectangular water tank with water sloshing

Journal of Fluids and Structures, 2018
Liquid storage tanks are widely used structures in industry. Their safety during an earthquake is important because damage to or the collapse of these structures can cause substantial material damage and human losses.

Shake table model testing and its application

The Structural Design of Tall and Special Buildings, 2007
AbstractThis paper presents a study of shake table testing for aseismic design of structure systems. Two reinforced concrete structure models of different scales were used first to implement and demonstrate the similitude concept using available testing equipment.

Shaking Table Test of Rock Slopes

2016
As it is known to all that the most direct and reliable way to study the response characteristics of rock slope seismic action is to conduct field test through seismic array network, which could intuitively reflect the motion features and seismic dynamic characteristics of rock slopes so as to provide precious original data for the future work.

Shake table tests on prestressed concrete frames

Materials and Structures, 1998
Results from small scale models of prestressed concrete frames, tested by a shake table simulating earthquake forces are presented. The primary curves (horizontal force-displacement relationships) and the hysteretic loops are determined experimentally. Concrete strength is approximately between 32 and 84 MPa, and two types of effective prestresses are ...

Shaking table testing of retrofitted 3-storey building

2013
The paper investigates the seismic performance of an existing 3-storey structure, built in the 70's. Not complying with capacity design principles, the structure is prone to soft-storey collapse, calling for retrofit through addition of shear walls. Two alternatives are considered with respect to the foundation: (a) conventional design; and (b) rocking

Shake table testing of museum display cases

Canadian Journal of Civil Engineering, 2008
Throughout history, objects of art have been damaged and sometimes destroyed in earthquakes. Research was undertaken to investigate the seismic vulnerability of art objects exhibited on display cases, and museum floor motions representative of Montreal seismic hazards were simulated for that purpose. Particular attention was paid to the effects on art
