Reliability assesment of real-time hybrid simulation with Newmark explicit algorithm

The purpose of this study is to conduct a reliability analysis of real-time hybrid\ud simulation results through a probabilistic approach. The first part of this research project\ud will analyze and compare actuator delay compensation methods for real-time hybrid\ud simulation. These methods include the N^-order polynomial, the linear acceleration\ud prediction method, the Newmark explicit prediction method and a newly developed dual\ud explicit prediction method. The discrete z transfer function method and sinusoidal\ud excitation method will be used to compare the amplitude magnification and phase shift\ud introduced by the compensation methods. The time delays can cause significant errors in\ud real-time hybrid simulation results and different compensation methods have been\ud developed for minimizing the effects of time delays. The second part of this research will\ud implement the compensation methods on the real-time hybrid simulation system in the\ud structural lab to experimentally evaluate the accuracy of the compensation methods. The\ud third part of this research will compare two type of the integration algorithms suited for\ud real-time testing. These algorithms are discrete z and Laplace transform function. A\ud probabilistic tool will be used for reliability analysis of real-time hybrid simulation\ud results
