CONSIDERATION ON APPLICABILITY TO REAL-TIME HYBRID SIMULATION OF THE CONTINUOUS HYBRID SIMULATION ALGORITHM

Abstract

 Real-time hybrid simulation (RTHS), in which loading tests and numerical analysis are conducted simultaneously, is considered to be one of the most effective methods for evaluating the dynamic performance of large-scale structures. On the other hand, an increase in calculation-task may affect the Continuous Hybrid Simulation Algorithm, which guarantees the smoothly actuator behaviour in RTHS, and may degrade the accuracy of simulation. In this study, we examined the effect of increased calculation-task on the accuracy of the RTHS, using theoretical equations and evaluating a virtual RTHS, and discussed the applicability of the Continuous Hybrid Simulation Algorithm to the RTHS. The results showed that even a slight increase in calculation-task significantly reduces simulation accuracy, and that calculation-task can be an important parameter of analytical model design in RTHS.
