Inelastic Displacement Response of RC Systems with Cyclic Deterioration-An Energy Approach

2012-01-01
Inelastic displacements of reinforced concrete systems are investigated by employing an energy-based approach. A hysteresis model is developed that accounts for stiffness degradation, strength deterioration and pinching. The model is calibrated by using experimental data from literature. Inelastic displacement ratios are calculated under a specific set of ground motion records with long effective durations. The results reveal the importance of deteriorating behavior under long duration excitations, especially for short and medium period structures. The last part of the study is devoted to the introduction of a simple empirical relationship for estimating the inelastic displacement demands of degrading RC structural systems.

Proposed minimum restoring force equations for seismic isolated structures
Görgülü, Ali Günalp; Dicleli, Murat; Department of Engineering Sciences (2019)
In this research study, a new set of restoring force equations are proposed for seismic isolated structures subjected to far fault ground motions (FFGM) and near fault ground motions (NFGM). For this purpose, 110 FFGM and 49 NFGM are selected. Then, nonlinear time history analyses (NLTHA) of SDOF seismic isolated structures are performed using the selected ground motions to obtain their residual and maximum displacements. The analyses are repeated for an extensive range of parameters including peak ground a...
Peak ground velocity sensitive deformation demands and a rapid damage assessment approach
Akkar, S; Sucuoğlu, Haluk (2003-05-13)
The effect of peak ground velocity (PGV) on the maximum inelastic deformation demand of simple, non-degrading structural systems is studied. Ground motion data sets are assembled for pre-defined ranges of PGV and they are used to conduct nonlinear response history analysis of single-degree-of-freedom (SDOF) systems. The study is focused on short and intermediate periods of vibration (T) and strength reduction factor (R) is used to define the lateral capacity of the structure. As part of the study, a simple ...
Progressive failure analysis of composite shells
Olcay, Yasemin; Darendeliler, Haluk; Department of Mechanical Engineering (2012)
The objective of this thesis is to investigate the progressive failure behavior of laminated fiber reinforced composite shell structures under different loading conditions. The laminates are assumed to be orthotropic and the first order shear deformation theory is applied. Three-node layered flat-shell elements are used in the analysis. To verify the numerical results obtained, experimental and analytical results found in literature are compared with the outputs of the study, and the comparison is found to ...
Comparison of the Overlapping Lattice and the Finite Element Approaches for the Prediction of the Collapse State of Concrete Gravity Dams
Soysal Albostan, Berat Feyza; Arıcı, Yalın; Binici, Barış; Tuncay, Kağan (2017-10-13)
Estimating the collapse limit state of concrete gravity dams within the framework of performance based design is challenging due to the uncertainty in modelling the response of these systems and the strong dependence of the behavior on the ground motion. In this context, the purpose of the study is to investigate the prediction capability of numerical tools in determining the collapse state of concrete gravity dams. The first tool used to this end is the classical finite element method with the smeared crac...
