Investigation of the cracking of CFRD face plates

2011-11-01
The primary goal of this study was to examine the cracking behavior of the face plate of a CFRD over its life cycle. Analyses of the construction stage, impounding, long-term deformation and earthquake loading were conducted in sequential phases using a 2-D plane-strain model with the appropriate nonlinear constitutive relationships for the dam constituents. The state of stress and the cracking behavior of the plate were found to be substantially different in the short and long term. Earthquake loading appears to be a critical load condition for the face plate; cracking increased significantly after ground shaking.

Evaluation of the performance of the face slab of a CFRD during earthquake excitation
Arıcı, Yalın (Elsevier BV, 2013-12-01)
The primary goal of this study was to examine the cracking behavior of the face plate of a CFRD during earthquake excitation. Analyses of the impounding stage and earthquake loading were conducted in sequential phases using a 2-D plane-strain model with the appropriate non-linear constitutive relationships for the dam constituents. The effect of rockfill stiffness and the face plate design properties on the seismic performance of the face plate was investigated. The crack widths on the plate increased with ...
Quantifying hydrophobicity of pyrite after copper activation and DTPI addition under electrochemically controlled conditions
Hicyilmaz, C; Altun, Naci Emre; Ekmekci, Z; Gokagac, G (Elsevier BV, 2004-07-01)
In this study, the response of the surface of pyrite to copper activation under electrochemically controlled conditions was investigated in the presence and absence of sodium diisobutyl dithiophosphinate (DTPI). The mechanism of interactions between the concerned reagents and pyrite was investigated using cyclic voltarnmetry in solutions of different pH. In addition, contact angle measurements were performed to determine the wetting behavior of the pyrite surface as a function of pulp potential and pH. The ...
Importance of Degrading Behavior for Seismic Performance Evaluation of Simple Structural Systems
Erberik, Murat Altuğ (Informa UK Limited, 2011-01-01)
This study focuses on effect of degradation characteristics on seismic performance of simple structural systems. Equivalent single degree of freedom systems are used for which the structural characteristics are taken from existing reinforced concrete (RC) frame buildings. Simulation of degrading behavior is achieved by considering actual experimental data. To obtain the seismic response of degrading structural systems, two different approaches are used: inelastic spectral analysis and fragility analysis. Ac...
Experimental evaluation of geomembrane/geotextile interface as base isolating system
Kalpakci, V.; Bonab, A. T.; Özkan, M. Yener; Gülerce, Zeynep (Thomas Telford Ltd., 2018-02-01)
The objective of this study is to evaluate the effect of the geomembrane/geotextile interface on the seismic response of small-to-moderate height structures. Three building models with first-mode natural frequencies changing between 2-4 Hz (representing two, three and four storey structures) were tested with and without the addition of geomembrane/geotextile interface using the shaking table test setup by employing harmonic and modified/ scaled ground motions. Experimental results showed that the geomembran...
Analysis of factors affecting strain distribution in geosynthetics
Kutay, ME; Güler, Murat; Aydilek, AH (American Society of Civil Engineers (ASCE), 2006-01-01)
Localized strains due to production defects, seams, and punctured zones significantly affect mechanical performance of geosynthetic materials. Accurate determination of localized strains becomes particularly important for quality control/quality assurance evaluation of these materials and may play a critical role in design problems. A battery of tensile tests was conducted on 12 different geosynthetics to assess the effects of seam type, puncture, and clamping techniques on strain distributions. Digital ima...
