PERFORMANCE-BASED SEISMIC DESIGN OPTIMIZATION FOR MULI-COLUMN RC BRIDGE PIERS, CONSIDERING QUASI-ISOLATION
In this paper an optimization framework is presented for automated performance-based seismic design of bridges consisting of multi-column RC pier substructures. The beneficial effects of fusing components on seismic performance of the quasi-isolated system is duly addressed in analysis and design. The proposed method is based on a two-step structural analysis consisting of a linear modal dynami...
متن کاملOPTIMAL SMART BASE ISOLATION SYSTEM FOR MULTIPLE EARTHQUAKES
Hybrid control system composed of a base isolation system and a magneto-rheological damper so-called smart base isolation is one of effective semi-active control system in controlling the seismic response of structures. In this paper, a design method is proposed for designing the smart base isolation system in order to achieve an effective performance under multiple earthquakes. The base mass, ...
متن کاملThe optimal age-based replacement policy for systems subject to shocks
In this article, two different systems subject to shocks occurring based on a non-homogeneous Poisson process (NHPP) are analyzed. Type –I system is consisted of a single unit and type –II system is consisted of two parallel units in which both units operate identically and simultaneously. In type –I system occurrence of a shock causes system stopping and consequently will be received minimal r...
متن کاملDesign of Sliding mode control for stochastic systems subject to packet losses
In this paper, we examine the design of a sliding mode control for stochastic systems with data packet losses. It is assumed that there is a network connection in the system's feedback loop and that part of the information may be lost during transmission. The innovation of this paper is to peresent a new method with better performance In this paper, we first consider an estimated method to com...
متن کاملDesign Principles of Seismic Isolation
In earthquake resistance design of structures, two general concepts have been used. The first is to increase the capacity of the structures to resist the earthquake load effects (mostly horizontal forces) or to increase the dynamic stiffness such as the seismic energy dissipation ability by adding damping systems (both devices and/or structural fuses). The second concept includes seismic isolat...
