An integrated computational platform for system reliability-based analysis of mixed-type highway bridge networks

Deterioration of aging infrastructure in United States is directing the attention of bridge managers and engineers toward more efficient inspection and evaluation techniques. Recent advances in reliability analysis methods justify new techniques that can be implemented in current practice. This paper discusses a network-level lifetime system reliability analysis method for bridges. A multi-phase research was carried out targeted toward an integrated system reliability-based, fully probabilistic analysis of highway bridge networks. The tasks included identification of random variables for different member types, quantification of random variable data (i.e., determination of statistical descriptors), derivation of standardized code-based limit state equations, investigation and implementation of load (increasing growth in traffic) and resistance (deterioration due to corrosion) models, and development and utilization of a network-level system reliability analysis program. Integration of these tasks was accomplished on a common computational platform. The proposed method for determining reliability profiles is illustrated using the results obtained for existing bridges within a selected highway bridge network.


A pattern-based approach to waterflood performance prediction using knowledge management tools and classical reservoir engineering forecasting methods
Artun, Emre; Vanderhaeghen, Maurice; Murray, Paul (Inderscience Publishers, 2016-01-01)
An efficient and rapid workflow is presented to estimate the recovery performance of an existing vertical-well, pattern-based waterflood recovery design using knowledge management and reservoir engineering in a collaborative manner. The knowledge management tool is used to gather production data and calculate pattern-based recoveries and injection volumes by defining pattern boundaries and allocating annual well injection/production volumes in a systematic manner. Classical reservoir engineering forecasting...
Integrated Probabilistic Delay Analysis Method to Estimate Expected Outcome of Construction Delay Disputes
Bektas, Sinasi; Birgönül, Mustafa Talat; Dikmen Toker, İrem (2021-02-01)
© 2020 American Society of Civil Engineers.Delays are almost inevitable in construction projects. They can have a devastating effects on the project. Therefore, proper analysis of delays and apportionment of liability is of utmost importance. Parties to construction contracts frequently employ various delay analysis methods to find out their entitlement to extension of time, or liquidated and ascertained damages. More often than not, technical analysis of delays performed by the parties yield distinct resul...
An exploratory study on features of intelligent office buildings and development of an assessment tool
Gündoğan, Handan; Dikmen Toker, İrem; Atasoy Özcan, Güzide; Department of Civil Engineering (2021-12)
Intelligent office buildings have a high-tech image that embraces advanced technologies to enhance the quality of life for building occupants and energy efficiency. The literature's exploration of the Intelligent Building (IB) concept indicated that the concept has broad aspects, which resulted in losing its focus. In this regard, this thesis aims to address two central questions of how the IB concept is currently interpreted by the building sector representatives and what are the intelligent features of an...
A knowledge-based risk mapping tool for cost estimation of international construction projects
Yildiz, Acelya Ecem; Dikmen Toker, İrem; Birgönül, Mustafa Talat; Ercoskun, Kerem; Alten, Selcuk (Elsevier BV, 2014-07-01)
Effective risk assessment and management is critical for success in international construction projects. This paper proposes a knowledge-based risk mapping tool for systematically assessing risk-related variables that may lead to cost overrun in international markets. The tool uses an ontology that relates risk and vulnerability to cost overrun [1] and a novel risk-vulnerability assessment methodology [2] to estimate potential risk paths that may emerge in international construction projects. The tool has b...

Over the last four decades, the negative impact of the building industry and the growing environmental crisis have led architects to develop sustainable design strategies for a better-performing built environment. Building performance tools, which are commonly used at the end of the design process, are not integrated into the design synthesis. Therefore, there is no integration between the performance parameters. In the literature, there are many studies focusing on the seamless integration of energy and da...
