Research on Base Isolation for Seismic Retrofitting of Adjacent Structures Connected with a Large Floor
Received: December 19, 2016 Revised: February 06, 2017 Accepted: March 20, 2017 Abstract: Introduction: Seismic isolation has been proven to be an efficient approach to seismic retrofitting of structures based on the concept of reducing the seismic forces by lengthening the structural fundamental vibration period. However, superstructures may collide with each other under seismic excitation as ...
متن کاملEarthquake Response of Adjacent Structures with Viscoelastic and Friction Dampers
We study the seismic response of two adjacent structures connected with a dry friction damper. Each of them consists of a viscoelastic rod and a rigid block, which can slide without friction along the moving base. A simplified earthquake model is used for modeling the horizontal ground motion. Energy dissipation is taken by the presence of the friction damper, which is modeled by the set-valued...
متن کاملSeparation between Adjacent Nonlinear Structures for Prevention of Seismic Pounding
Four existing methods to calculate critical separation distances between adjacent nonlinear hysteretic structures are evaluated through Monte-Carlo simulations, for which seismic excitation is characterized as a nonstationary random process. All the methods use the well-known Double Difference Combination rule, but follow different approaches to calculate the correlation coefficient ρ. Results ...
متن کاملAnalytical Investigation of TADAS Damper Applied in Seismic Rehabilitation & Design of Concrete Structures
In recent years, destructive earthquakes have shown the deficiencies of the existing buildings. One of the most effective mechanisms for dissipating the earthquake energy is inelastic deformation of the steel components. The objective of this research is to study the application of metallic dampers for dissipation of the earthquake energy and to investigate the behavior of concrete structures i...
