Performance Characteristics of Cold In-Place Recycling Mixtures
Publisher: ASCE
Abstract: Cold in-place recycling (CIR) of asphalt pavements is a process that has successfully been used for many years. The use of CIR for rehabilitation offers many advantages over reconstruction. When looked at closely its ...
Effect of Strain History and Mixture Proportions on Early-Age Cement Paste and Mortar Stress Relaxation
Publisher: ASCE
Abstract: The influence of sand particles, aging, and water–cement (w/c) ratio on the viscoelastic relaxation modulus of cement paste and mortars was measured at early ages (1–28 days). Furthermore, the relaxation modulus ...
Failure Load and Collapse Mode of an RC Beam in a Large Collapsed Roof
Publisher: ASCE
Abstract: The present work focused on the determination of the collapse load and failure mode of a reinforced concrete (RC) of collapsed framed structure constructed in the South of Italy that failed in 2004. Information available ...
Seismic Rehabilitation of Steel Arch Bridges Using Nonlinear Viscous Dampers: Application to a Case Study
Publisher: ASCE
Abstract: Old steel arch bridges commonly need rehabilitation interventions because of their insufficient lateral resisting capacity against seismic loads. A localized strengthening method is not always applicable to such bridges ...
Implementing a TQM Framework for Public Services in Iraq: An Exploratory Study
Publisher: ASCE
Abstract: Public services in Iraq have been deemed to perform unsatisfactorily. In this study, the theory of total quality management (TQM) is used to identify the quality shortcomings of public service projects in Iraq. Accordingly, ...
Impact of Environmental Factors on the Condition Rating of Concrete Bridge Decks Using Statistical-Distribution Methods
Publisher: ASCE
Abstract: Keeping bridges in good condition during their service lives continues to be a challenge. Additionally, the condition assessment of concrete bridge decks is complicated as it is influenced by several factors. Environmental ...
Demand and Supply of Rotational Ductility in Flexible Extended Shear Tab Connections
Publisher: ASCE
Abstract: Extended shear tab connections have a long history in the steel construction industry as a practical solution to many framing problems, such as framing the supported member to the weak axis of a column without the need for ...
Causal Factors for Engineering Design Defects and Their Impacts
Publisher: ASCE
Abstract: Although research has identified factors affecting engineering design defects, these defects remain the primary cause of construction phase rework and poor project performance. The authors consolidated similar causal factors ...
Statistical Approach to Modeling Reduced Shear Capacity of Corrosion-Damaged Reinforced Concrete Beams
Publisher: ASCE
Abstract: In the 2017, ASCE graded the national infrastructure of the United States as D+ overall. The ASCE gave the national School Buildings category a D+ grade and the Bridges category a C+ grade. Steel corrosion is the main ...
Earthquake Response Control of Isolated Bridges Using Supplementary Passive Dampers
Publisher: ASCE
Abstract: Earthquake response control of base-isolated bridges using supplementary passive dampers is presented. A benchmark highway overcrossing located in California is selected to indicate the effectiveness of such hybrid response ...
