Energy dissipation characteristics of structural members which exhibit both strength and stiffness deterioration under imposed displacement reversals are investigated. In the experimental part, 17 reinforced concrete beam specimens were tested under constant and variable amplitude inelastic displacement cycles. The constant-amplitude tests were employed to determine the low-cycle fatigue behaviour of specimens where the imposed displacement amplitude was the major variable. A two-parameter fatigue model was developed in order to express the variation of dissipated energy with the number of displacement cycles. This model was then used to predict the energy dissipation of test specimens subjected to variable-amplitude displacement cycles simulating severe seismic excitations. It has been demonstrated that the remaining energy dissipation capacity in a forthcoming displacement cycle is dependent on the energy dissipated along the completed displacement path. Moreover, it is observed that total energy dissipation is dependent on the length of the displacement path. Copyright (C) 2003 John Wiley Sons, Ltd.

EARTHQUAKE GROUND MOTION CHARACTERISTICS AND SEISMIC ENERGY-DISSIPATION Sucuoğlu, Haluk (Wiley, 1995-09-01) The sensitivity of seismic energy dissipation to ground motion and system characteristics is assessed. It is found that peak ground acceleration, peak ground velocity to acceleration (V/A), dominant period of ground excitation and effective response duration are closely correlated with the energy dissipated by a SDOF system. Ductility ratio and damping ratio have no significant influence on the energy dissipation. An energy dissipation index is proposed for measuring the damage potential of earthquake groun...
Seismic response assessment of a stiff structure Kazaz, I; Yakut, Ahmet; Gulkan, P (Wiley, 2006-05-01) Seismic response of a lightly reinforced stiff shear-wall structure subjected to ground motions grouped as near- or far-field according to their distance to causative faults is investigated. A model structure that had earlier been studied both experimentally and analytically in the context of a co-ordinated research project is re-examined. The structure is a five-storey lightly reinforced shear-wall model subjected analytically to 55 ground motion records from firm soil sites. Several response parameters ar...
Earthquake fault rupture - Shallow foundation interaction in undrained soils: A simplified analytical approach Yılmaz, Mustafa Tolga (Wiley, 2007-01-01) The interaction between normal or reverse fault ruptures and shallow foundations resting on a homogeneous undrained soil layer is investigated. After performing a thorough set of non-linear finite element simulations, three simple kinematic mechanisms are proposed to predict the conditions for the fault rupture to be diverted by the foundation. The results obtained by both numerical and analytical approaches are in good agreement, and support the adequacy of the proposed mechanisms.
Stochastic geometry model of rock mass fracture network in tunnels Azarafza, Mohammad; Akgün, Haluk; Asghari-Kaljahi, Ebrahim (Geological Society of London, 2018-08-01) Geometric distributions of fractures or discontinuities control the behaviour, and limit the strength and the stability of rock masses where the best stabilization and improvement method for that rock mass could be achieved based on favourable discontinuity geometry. This study introduces an algorithm named 'Stochastic Geometry Model of Fractures Network in Tunnels (SGMFNT)', which was developed with the MA THEMATICA software. The SGMFNT method provides a fractures geometric distribution database to aid dis...
Effect of near-fault ground motion and damper characteristics on the seismic performance of chevron braced steel frames Dicleli, Murat (Wiley, 2007-06-01) This study is aimed at comparing the seismic performance of steel chevron braced frames (CBFs) with and without fluid viscous dampers (FVDs) as a function of the characteristics of the near-fault (NF) ground motion and FVD parameters. For this purpose, comparative nonlinear time history (NLTH) analyses of single and multiple storey CBFs with and without FVDs are conducted using NF ground motions with various velocity pulse periods scaled to have small, moderate and large intensities. Additionally, NLTH anal...
