The main goal of this study is to examine the relationships between determinants of safety performance of construction sites. To achieve this goal, 168 observable variables and 16 latent dimensions that affect safety performance of construction sites were collected through extensive literature reviews, expert opinions, and face-to-face interviews. A questionnaire form was developed and administered to construction professionals as a data-collection tool about the observable variables and latent dimensions. A total of 180 responses were achieved through data collection. Relationships between observable variables and latent dimensions of the safety performance of construction sites were studied and a multidimensional safety performance model was proposed. The proposed multidimensional safety performance model was supported by structural equation modeling (SEM) analysis. Moreover, 16 latent dimensions with respect to their relative weights and recommendations for construction safety professionals are provided to improve the safety performance of construction sites.

Development of of a safety performance index assessment tool by using a fuzzy structural equation model for construction sites Gunduz, Murat; Birgönül, Mustafa Talat; Ozdemir, Mustafa (Elsevier BV, 2018-01-01) The main goal of this study is to propose a safety performance index assessment tool to improve the construction safety. Formulation of the safety performance index of construction sites is achieved upon a validated multidimensional safety performance model. The contribution of this study could be summarized as incorporation of fuzzy set theory into structural equation modeling to develop a safety performance index assessment software tool. Case studies were conducted at 11 international construction sites ...
Web-Based Risk Assessment Tool Using Integrated Duration-Cost Influence Network Model Dikmen Toker, İrem; Birgönül, Mustafa Talat (American Society of Civil Engineers (ASCE), 2012-09-01) The major challenges of project risk assessment may be attributed to the knowledge requirements for determining the level of uncertainty and the development of complex models to predict project outcomes. The duration-cost influence network is an adequate model that can be used for activity-based risk modeling. In this study, a scenario analysis feature is added to this model and a Web-based tool is developed that can be used to calculate risk-adjusted duration and cost, considering the risks affecting cost ...
Nonlinear analysis of R/C low-rise shear walls Mansour, Mohamad Y.; Dicleli, Murat; Lee, Jung Yoon (SAGE Publications, 2004-08-01) An analysis method for predicting the response of low-rise shear walls under both monotonic and cyclic loading is presented in this paper. The proposed analysis method is based on the softened truss model theory but utilizes newly proposed cyclic constitutive relationships for concrete and steel bars obtained from cyclic shear testing. The successfulness of the analysis method, when combined with new materials constitutive relationships, is checked against the test results of 33 low-rise shear walls reporte...
Identification of Risk Paths in International Construction Projects Using Structural Equation Modeling Eybpoosh, Matineh; Dikmen Toker, İrem; Birgönül, Mustafa Talat (American Society of Civil Engineers (ASCE), 2011-12-01) The major aim of this research is to demonstrate that causal relationships exist among various risk factors that necessitate identification of risk paths, rather than individual risk factors, during risk assessment of construction projects. International construction projects have more complex risk-emergence patterns because they are affected by global and foreign country conditions and project-related factors. Identification of a network of interactive risk paths, each of which initiated from diverse vulne...
Lifetime Performance Analysis of Existing Reinforced Concrete Bridges. I: Theory Akgül, Ferhat (American Society of Civil Engineers (ASCE), 2005-06-01) In this first part of a two-part paper, a general methodology for lifetime performance analysis of existing reinforced concrete bridges is presented. The framework for the methodology is established by identifying four distinct categories: limit state equations, random variables, deterministic parameters, and constant coefficients. The limit state equations are derived by strictly adhering to the load and capacity formulas and requirements set forth in AASHTO specifications. Generality is pursued by establi...
