Rapid Bridge Replacement: Processes, Techniques, and Needs for Improvements
(American Society of Civil Engineers, 2006-11-01)The terrorist attack on September 11, 2001 and subsequent potential threats to the United States transportation systems have presented an urgent need to develop emergency response plans in order to quickly react to the ... -
Intelligent Painting Process Planner for Robotic Bridge Painting
(American Society of Civil Engineers, 2007-04-01)Due to increased government regulations on environment, health, and safety, the cost of on-site bridge painting has quadrupled over the past several years. The construction industry faces a great challenge in how to control ... -
Comparison of characteristics between fatal and injury accidents in the highway construction zones
(Elsevier, 2008-04)Highway construction zone safety has been a research focus in many countries for many decades. In the United States, regardless of the research efforts devoted, highway construction zones remain a serious safety concern ... -
Development of crash-severity-index models for the measurement of work zone risk levels
(Elsevier, 2008-09)Highway work zones interrupt regular traffic flows and create safety problems. Improving safety without sacrificing the main function of highways is a challenging task that traffic engineers and researchers have to confront. ... -
Effectiveness of temporary traffic control measures in highway work zones
(Elsevier, 2009-03)In the United States, hundreds of people lose their lives each year and many more are injured due to vehicle crashes in the work zones. Over the years, temporary traffic control (TCC) measures have been developed and ... -
Bond Characteristics of ASTM A1035 Steel Reinforcing Bars
(American Concrete Institute, 2009-07)The results of a coordinated research program on the bond characteristics of the high-strength steel reinforcing bars that conform to ASTM A1035 are presented. Concrete with nominal strengths of 5000 and 8000 psi (35 and ... -
Highway Work Zone Risk Factors and Their Impact on Crash Severity
(American Society of Civil Engineers, 2009-09-15)Numerous factors may contribute to high-severity crashes in highway work zones. Identifying these factors and then alleviating their impact is a challenging task that traffic engineers and researchers have to confront. In ... -
Analyzing motorists’ responses to temporary signage in highway work zones
(Elsevier, 2010-02)For decades, the importance of highway work zone safety has increased considerably with the continual increase in the number of highway work zones present on highways for repairs and expansion. Rural work zones on two-lane ... -
Comparison of Contract General Conditions between United States and China
(American Society of Civil Engineers, 2010-12-01)In light of the fact that construction projects are expensive, complex, and time-consuming undertakings, a well-written contract that specifies each participant’s duties and obligations is required. Furthermore, a well-written ... -
Low-Cracking, High-Performance Concrete Bridge Decks: Case Studies over First 6 Years
(SAGE Publications, 2010-01-01)Cracks in concrete bridge decks provide easy access for water and deicing chemicals that shorten the life of the deck, and field surveys show that the problem has become progressively more severe since at least the 1980s. ... -
Determining the drivers’ acceptance of EFTCD in highway work zones
(Elsevier, 2011-05)Traffic safety is a major concern in the temporary one-lane, two-way highway work zones due to the increasing of construction and maintenance operations. To prevent rear-end crashes and to mitigate the severity of these ... -
A Petri net simulation model for virtual construction of earthmoving operations
(Elsevier, 2010-11-06)A common and extended Petri net simulation framework for virtual construction of earthmoving operations is developed to simulate dynamic changes of workflow and information flow in the earthmoving construction process and ... -
Measuring Bridge Construction Efficiency Using the Wireless Real-Time Video Monitoring System
(American Society of Civil Engineers, 2012-04)To enhance the efficiency of bridge construction, the wireless real-time video monitoring system (WRITE) was developed. Utilizing the advanced technologies of computer vision and artificial neural networks, the developed ... -
Effect of Corrosion Inhibitors on Concrete Pore Solution Composition and Corrosion Resistance
(American Concrete Institute, 2013-09)Three commercially available corrosion inhibitors—calcium nitrite, a solution of amines and esters, and an alkenyl-substituted succinic acid salt—are evaluated in conjunction with conventional reinforcement in concrete ... -
Evaluating the Performance of Existing Reinforcement for Oklahoma Bridges
(University of Kansas Center for Research, Inc., 2020-11)The ever-increasing use of deicing salts poses results in a constant threat to transportation infrastructure, particularly bridge deck components, due to corrosion of the reinforcing steel in concrete structures. For over ... -
Experimental Study on Minimum Depth of Interior Joints for Special Moment Frames with High-Strength Reinforcement and Concrete
(Japan-Korea-Taiwan Seminar on Earthquake Engineering for Building Structures (SEEBUS), 2019-12)ACI 318-19 permits the use of Grade 690 bars for primary reinforcement of special structural walls, but not for special moment frames because of insufficient experimental evidence of frame joints. Where Grade 690 bars are ... -
Analytical Investigation of Saddle Connections for Overhead Sign Trusses with Respect to Strength and Fatigue Performance
(University of Kansas Center for Research, Inc., 2020-08)Bridge-type overhead truss sign structures (OHTSS) are widely used over active highways across the states. An OHTSS is comprised of a 3D truss and two support frames at each end. The structures are usually made of steel ... -
Determination of Fatigue Resistance of Coupler Connections in Aluminum Overhead Truss Structures
(University of Kansas Center for Research, Inc., 2020-08)Overhead truss sign structures (OHTSS) are widely used over highways across the nation. An overhead truss sign structure is comprised of a truss and two supporting frames at each end, and can be made using aluminum or ... -
Dynamic Performance of Cantilevered Sign Trusses for Fatigue
(University of Kansas Center for Research, Inc., 2019-07)Cantilevered overhead sign structures (COSS) experience cyclic loading due to stochastic loads such as natural wind gusts (NWG). Wind loading can produce large deflections in the cantilever and large-magnitude stresses can ... -
Skewed Steel Bridges, Part II: Cross-Frame and Connection Design to Ensure Brace Effectiveness
(University of Kansas Center for Research, Inc., 2017-03)Skewed bridges in Kansas are often designed such that the cross-frames are carried parallel to the skew angle up to 40°, while many other states place cross-frames perpendicular to the girder for skew angles greater than ...
