This study introduces the first application of nonlinear signal-based control (NSBC) to shake table experiments with sliding masses. NSBC utilising a signal was specifically developed for system control. In steel structure, it realised seismic acceleration record on near 100% accuracy even when structure displayed characteristics due yielding its components. Regarding severity, is stronger than...

In earthquake engineering, structural models are validated by performing a time history analysis and comparing its maximum to the response obtained shake table test. It has been shown that this is sufficient (but not necessary) precondition accept numerical model. Numerical can fail predict planar rocking of rigid block, but may succeed in predicting statistics an ensemble ground motions. As se...

There is great enthusiasm about the potential of computers for enhancing student learning in science and engineering. The Structural Engineering Department at the University of California, San Diego (UCSD) has initiated the Webshaker Pilot Project with the goal of facilitating accessibility to live, on-demand, experimental testing earthquake engineering applications. The project is presented in...
