Sentence examples for ssi system from inspiring English sources
Enhanced Frequency Domain Decomposition (EFDD) and Stochastic Subspace Identification (SSI), system identification methods, were applied.
It is also shown that using an EFSDOF oscillator is not appropriate for predicting the constant-ductility spectra when the initial damping ratio of the SSI system exceeds 10%.
An equivalent fixed-base single-degree-of-freedom oscillator is adopted to capture the salient features of an actual soil-structure interaction (SSI) system in order to facilitate the design process.
The wind load which caused the maximum base moment was applied to the SSI system and for this lateral load the base moment of chimney with flexible base was evaluated.
In this approach, ˜Cy is obtained as the unreduced seismic coefficient, C, of an equivalent fixed-base structure with natural period ˜T, the natural period of the elastic SSI system, and with inelastic reduction factor equal to the λ-root of the fixed-base reduction factor, where λ=˜T/T, and T is the elastic natural period of the structure ignoring SSI.
E. breviscapus exhibits an SSI system of SI as other Asteraceae species.
Several details are discussed, including the effect of simulation time step sizes, comparison of implicit and explicit methods, effects of increasing nonlinearity in the SSI system, and the nonlinear seismic responses of the SSI systems in cases of considering vs. not considering SSI effect.
