Experimental testing is an essential tool for understanding how structures respond to
extreme events. Methods currently used to determine the behavior of structural systems …

Compensation of delay and dynamic response of servo‐hydraulic actuators is critical for
stability and accuracy of hybrid experimental and numerical simulations of seismic response …

This paper presents a new method, called the equivalent force control method, for solving
the nonlinear equations of motion in a real‐time substructure test using an implicit time …

This paper presents a detailed analysis of a real‐time pseudodynamic test system using a
system transfer function. The analysis considers the actuator control scheme, the dynamics …

The purpose of earthquake simulators is to reproduce reference accelerations on a shake
table. However, acceleration control is extremely difficult in earthquake simulators due to an …

Shake tables provide a direct means by which to evaluate structural performance under
earthquake excitation. Because the entire structure is mounted on the base plate and …

An electrohydraulic shaking table is an essential experimental facility in many industrial
applications to real-time simulate actual vibration situations including structural vibration and …

This paper presents comparisons of the performances of three semiactive control algorithms
for use with multiple magnetorheological (MR) dampers. The three controllers are (1) the …

A new approach to dynamic force control of mechanical systems, applicable in particular to
frame structures, over frequency ranges spanning their resonant frequencies is presented …

The main objective of this paper is to investigate the tracking (signal reproduction) capability
of the UCSD-NEES shake table system through a series of broadband and harmonic …
