For accurate analytical assessment of performance and damage in reinforced concrete members, well-defined deformation limits at particular damage states are required. With advanced and computationally intensive finite element analyses, we establish deformation limits at yield and ultimate limit states for adequately confined rectangular reinforced concrete structural walls in terms of drift ratio, plastic rotation, and curvature. To investigate the deformation limits of structural walls, a parametric study on isolated cantilever wall models is performed. The primary variables of the parametric study are the shear-span-to-wall-length ratio, wall length, axial load ratio, normalized shear stress, the amount of horizontal web reinforcement, and the amount of longitudinal reinforcement at the confined boundary of structural wall models. Expressions and limit values are proposed for yield and ultimate deformation capacity of structural walls, based on the most influential parameters. The proposed equations are found to be promising when compared to results of experiments. [DOI: 10.1193/1.4000059]

Evaluation of Seismic Response Factors for Eccentrically Braced Frames Using FEMA P695 Methodology KUŞYILMAZ, Ahmet; Topkaya, Cem (SAGE Publications, 2016-02-01) This paper reports details of a numerical study undertaken to evaluate seismic response factors for steel eccentrically braced frames (EBFs) using the FEMA P695 methodology. Six archetypes were designed by making use of the current U.S. specifications, and their behavior was assessed by making use of nonsimulated collapse models. Results indicate that the current values of response factors result in designs with higher collapse probabilities than expected. Two modifications were developed to bring the colla...
Seismic Risk Prioritization and Retrofit Cost Evaluation of Code-Deficient RC Public Buildings in Turkey Sucuoğlu, Haluk; Yakut, Ahmet (SAGE Publications, 2015-02-01) A risk prioritization procedure is developed for deficient concrete public buildings within the scope of a seismic risk reduction program. The main purpose is identifying public buildings with high damage risk in a region for efficient retrofit investments. Regularity of structural systems and repeatability of deficiencies in public buildings provide opportunities for developing simple and reliable assessment procedures. The proposed procedure is based on calculating a risk index from the comparison of late...
Development of Fragility Curves for Single-Column RC Italian Bridges Using Nonlinear Static Analysis Perdomo, Camilo; Monteiro, Ricardo; Sucuoğlu, Haluk (Informa UK Limited, 2020-05-07) The main objective of this study is to assess the accuracy and suitability of Nonlinear Static Procedures (NSPs) in the development of analytical damage fragility curves for seismic risk assessment of large portfolios of Reinforced Concrete (RC) bridges. Seven NSP approaches, from widely used single-mode conventional pushover-based approaches to the more rigorous multi-mode conventional or adaptive pushover-based procedures are implemented. By systematically comparing fragility curve estimations in terms of...
Strength of sands in wedge shear, triaxial shear, and shear box tests Mirata, Tuerker; Erzin, Yusuf (ASTM International, 2007-03-01) Limited tests had indicated peak drained values of angle of internal friction (of gravelly sands measured in the cylindrical wedge shear test (cylwest) to be relatively closer to the (expected from plane strain tests than from triaxial tests. Such a difference was not obtained between the results of the prismatic wedge shear test (priswest) and the triaxial test on gravels and crushed rock. In this study, six sands with <3.35 mm particles were tested. It was seen that the main reason for the difference betw...
Elastic and Inelastic Near-Fault Input Energy Spectra Alici, F. Soner; Sucuoğlu, Haluk (SAGE Publications, 2018-05-01) The main purpose of this study is to develop a reliable model for predicting the input energy spectra of near-fault ground motions for linear elastic and inelastic systems, and to evaluate the effect of damping and lateral strength on energy dissipation demands. An attenuation model has been developed through one-stage nonlinear regression analysis. Comparative results revealed that near-fault ground motions have significantly larger energy dissipation demands, which are very sensitive to earthquake magnitu...
