“…Moens and Hanns (2011) provided a state of the art for the interval analysis. More recently, the interval analysis using Taylor series expansion was proposed in the references (Chen et al, 2002(Chen et al, , 2009Chen and Wu, 2004;Fujita and Takewaki, 2011;Fujita et al, 2015;Okada et al, 2016).…”

An evaluation method of robustness of base-isolation building-connection hybrid controlled building structures is developed by introducing a measure for robustness (robustness function) and considering shallow and deep ground uncertainties. The earthquake ground-motion amplitude at the earthquake bedrock is evaluated by the Boore's stochastic method including the fault rupture and the wave propagation into the earthquake bedrock. Then, the phase angle property at the earthquake bedrock is investigated by introducing the concept of phase difference, which is defined for each earthquake type. The ground-motion amplification in the shallow and deep ground is expressed by the one-dimensional wave propagation theory. The robustness of base-isolation buildingconnection hybrid controlled building structures is measured by use of the robustness function due to Ben-Haim (2006) and is evaluated by taking full advantage of the updatedreference-point method. It is shown that, as the total quantity of damping coefficients of connection dampers increases, the robustness for the deformation of the baseisolation story becomes larger without the drastic reduction of the robustness for the top acceleration.

“…A genetic algorithm (GA) is used for investigating the accuracy of the proposed method (see ''New uncertainty analysis method''). Although a preliminary and limited investigation has been conducted in Fujita et al [22], more detailed investigation including a new uncertainty case (case 2 in ''Scenario of uncertainty in ground profiles'') and practical applications to actual sites will be presented (see ''Application of NURP method to actual ground'').…”

Robustness analysis of the seismic pile response of a structure-pile-soil system with uncertain soil properties and concrete Young's modulus is presented in this paper. The bounds of the bending moment of a pile are investigated by means of the previously proposed uncertainty analysis method (Updated Reference-Point method) and the newly developed revised method (NURP method). An efficient finite-element model of a structure-pile-soil system with smart displacement functions for connecting elements is adopted and a response spectrum method is applied in the evaluation of the seismic pile responses of the system. Two cases of soil uncertainties resulting from different uncertainty mechanisms are considered. It is shown that the worst combination of uncertain soil parameters can be determined by the NURP method in an accurate manner.
