Numerical Simulation of three Base Isolation Systems for Earthquake Protection of Structures

2003-10-10
In a previous paper [1&2] a base isolation system was proposed for earthquake protection of structures. The system incorporates spherical supports for the base, a specially designed spring-cam system to keep the base rigidly supported under normal conditions and to allow it to move for the duration of the earthquake under the constraint of a spring with optimized stiffness characteristics. A high-rise structure was considered to investigate the feasibility of the concept. The simulation of the system response shows a 6 times reduction of the transmitted force as a result of using the proposed design in the considered case. This paper extents the previous study in order to compare with the counterpart base isolation systems, Rubber Steel Composite Bearing and Frictional Pendulum System (FPS), in the case 3 story structure subjected the El Centro earthquake.

Kaplan, Halit; Dölen, Melik (2003-10-10)
This paper investigates the seismic response and optimum design of a base isolation system for earthquake protection of structures. The system incorporates spherical supports for the base, a specially designed spring-cam system to keep the base rigidly supported under normal conditions and to allow it to move for the duration of the earthquake under the constraint of a spring with optimized stiffness characteristics. A single degree of freedom structure was considered to investigate the feasibility of the c...
Dynamic analyses of isolated structures under bi-directional excitations of near-field ground motions
Ozdemir, Gokhan; Akyüz, Uğurhan (2012-01-01)
Nonlinear response history analyses (NRHA) of a 3-story isolated reinforced concrete (RC) building are carried out under both uni- and bi-directional earthquake excitations of near-field records. NRHA are conducted for a wide range of yield strength (Q/W) of lead rubber bearings (LRB), and isolation period (T). Selected near-field records are used to investigate both the contribution of orthogonal components on maximum isolator displacements and accuracy of equivalent lateral force (ELF) procedure on estima...
Comparative study of base isolated systems
Türkmen, Fatih; Akyüz, Uğurhan; Department of Civil Engineering (2002)
This thesis is mainly concerned with providing brief knowledge about the effects of earthquakes on buildings and their response to earthquake forces. Principles of advanced passive earthquake resistant design techniques are also presented. Next, the use of the most common passive earthquake resistant design technique; i.e., base isolation is described, with its historical background, main principles and usage in the world. In order to evaluate the effectiveness of base isolation, and the performance of base...
Experimental evaluation of geomembrane / geotextile interface as base isolating system
Taheri Bonab, Amin; Gülerce, Zeynep; Kalpakcı, Volkan; Department of Civil Engineering (2016)
The objective of this study is to evaluate the effect of the composite liner seismic isolation system on the seismic response of small-to-moderate height structures. For this purpose, a building model with the natural frequency of 3.13 Hz (representing 3-4 story structures) was tested with and without the addition of composite liner system using the shaking table test set-up by employing harmonic and modified/ scaled ground motions. Experiment results showed that the composite liner seismic isolation system...
SEISMIC PERFORMANCE COMPARISON OF BASE-ISOLATED HOSPITAL BUILDING WITH VARIOUS ISOLATOR MODELING APPROACHES
Çabuk, Eser; Akyüz, Uğurhan; Department of Civil Engineering (2021-9-09)
In Turkey, seismic base isolation have become mainly used passive earthquake control system especially among hospital structures after the amendment of Ministry of Health in 2014, regulating the design of hospitals in high seismic zones. Rubber and sliding type of isolators have been applied, and several different hysteresis models, which are essentially acceptable in seismic codes, were used in their design process. However, due to the complexity in the development of highly nonlinear models, engineers ten...
