Special issue on stochastic dynamics and reliability analysis of structural systems subject to environmental excitations
No full textPerformance-based seismic risk assessment for buildings equipped with linear and nonlinear viscous dampers
No full textThis paper introduces an efficient methodology for assessing the seismic risk of structural systems equipped with linear and nonlinear viscous damping devices while accounting for the uncertainties affecting both seismic input and model parameters. The proposed methodology employs a combination of efficient and accurate analytical and simulation techniques to estimate the probabilistic properties of the structural response under a seismic input modeled as a non-stationary stochastic process.
The effectiveness of the proposed methodology is illustrated through a parametric study, with respect to the dampers’ properties, of the performance of two adjacent steel buildings connected by linear and nonlinear viscous dampers. The results of the study provide useful information regarding the accuracy of the approximations introduced by the proposed reliability assessment approach, and the effectiveness of the added dampers in reducing the system seismic risk

Efficient Approach for the Reliability-Based Design of Linear Damping Devices for Seismic Protection of Buildings
Full text linkThis paper presents an efficient reliability-based methodology for the seismic design of viscous/viscoelastic dissipative devices in independent and/or coupled buildings. The proposed methodology is consistent with modern performance-based earthquake engineering frameworks and explicitly considers the uncertainties affecting the seismic input and the model parameters, as well as the correlation between multiple limit states. The proposed methodology casts the problem of the dampers’ design for a target performance objective in the form of a reliability-based optimization problem with a probabilistic constraint. The general approach proposed in this study is specialized to stochastic seismic excitations and performance levels for which the structural behavior can be assumed as linear elastic. Under these conditions, the optimization problem is solved efficiently by taking advantage of existing analytical techniques for estimating the system reliability. This analytical design solution is an approximation of the optimal design and can be used as a hot-start point for simulation-based techniques, which can be employed to find the optimal design solution. An efficient correction formula is proposed to obtain an improved design solution that is generally sufficiently close for engineering purposes to the optimal design solution obtained from significantly more-computationally-expensive simulation-based techniques. The proposed design methodology is illustrated and validated by considering two steel buildings modeled as linear elastic multiple-degree-of-freedom systems for different linear damper properties and collocation, for both independent and coupled configurations
