Optimization Criteria In Design Of Seismic Isolated Building
AIP Conference Proceedings, 2008Use of new anti‐seismic techniques is certainly suitable for buildings of strategic importance and, in general, in the case of very high risk. For ordinary buildings, instead, the cost of base isolation system should be balanced by an equivalent saving in the structure.

Design of Structures with Seismic Isolation
2001This chapter surveys the principles, benefits, and the feasibility of seismic isolation. The basic principles of seismic isolation are introduced first. Contrary to a perception held by many engineers, neither the concept of seismic isolation is new nor its application is necessarily complex.

Seismic Isolation Design of Multistory Building
Applied Mechanics and Materials, 2012Design process and the nonlinear time history analysis for base isolation system is performed in this paper. The results show that the earthquake acceleration and displacement response of isolated structure can be significantly reduced. Application of the isolation system to improve the seismic capacity of the structure,can effectively reduce the ...

On the Design of an Optimal Seismic Isolation System
SAE Technical Paper Series, 1985<div class="htmlview paragraph">A competing variables approach is developed for determining an optimal choice of stiffness and damping for minimization of the dynamic response of a single-degree-of-freedom (SDOF) system subjected to random base excitation.

Design and analysis of seismically isolated structures
Nuclear Engineering and Design, 1991Abstract This paper describes developing methodology for performing three-dimensional (3D) analysis of individual seismic bearings and for simulating the 3D system response of isolated reactor structures (superstructure, isolators, basemats, etc.) including the surrounding soil under earthquake excitation. In addition, programs for elastomer research

Design of Metamaterials for Seismic Isolation
2016This study assesses the implementation of locally resonant metamaterials in seismic isolation applications, by investigating their potential feasibility in low frequency bands. To this end, via adoption of both Blochs Theorem and classical vibration analysis, both one-dimensional and two-dimensional mass-in-mass lattices are analyzed in overlapping ...

Deformation‐based design of seismically isolated bridges
Earthquake Engineering & Structural Dynamics, 2022AbstractA performance‐based design procedure is proposed for seismically isolated bridges with/without supplemental energy dissipation devices. Considering multiple performance levels (PLs), the proposed method initially identifies the critical hazard level and “near‐optimal” alternatives of the isolation system.

SEISMIC RELIABILITY-BASED DESIGN OF STRUCTUTRES ISOLATED BY FPS
Proceedings of the VII European Congress on Computational Methods in Applied Sciences and Engineering (ECCOMAS Congress 2016), 2016The paper deals with the seismic reliability of base-isolated structural systems equipped with friction pendulum isolators (FPS) in order to provide useful design recommen-dations. A two-degree-of-freedom model is adopted by accounting for the superstructure flex-ibility, whereas the FPS isolator behaviour is described by adopting a widespread model ...

Design Aspects in Seismic Isolation: Application to Retrofit Churches
International Journal of Architectural Heritage, 2008The severe damage to masonry buildings after earthquakes has pointed out the need of studying new seismic protection techniques in order to guarantee appropriate safety levels against earthquakes. In historical buildings, such as basilica churches, a seismic rehabilitation should have also a minimum impact on the construction, preserving the original ...

Design and manufacturing of fiber reinforced elastomeric isolator for seismic isolation
Journal of Materials Processing Technology, 2002Abstract In this paper an experimental analysis is presented for the mechanical characteristics of multi-layer elastomeric isolation bearings where the reinforcing element—normally steel plates—are replaced by a fiber reinforcement. The fiber reinforced elastomeric isolator (FREI), in contrast to the steel reinforced elastomeric isolator (SREI) which
