II - Multiple Floors Moment Resisting Frame Real-time Hybrid Simulation

This experimental validation procedures follows the worst-case RTHS configuration, similarly as the single floor MRF test. The mass is primarily assumed computationally, but the stiffness is largely tested physically. A series of validation tests are configured by varying the computational mass on both floors. The input El-Centro earthquake intensity is scaled accordingly for each configuration (see table below), to accommodate the actuator force limit and stroke length constraints. The reference structure assumes Rayleigh damping of 2% for the first two modes in each configuration. Configuration 1, 2, 3, 4 m1(kg) 2000, 4000, 4000, 8000 m2(kg) 2000, 2000, 4000, 8000 Eq.Intensity 0.15, 0.15, 0.1, 0.07
