QUANTIFYING SHALLOW DEPTH CONCRETE DELAMINATIONS USING IMPACT ECHO
(2020-07-20)
Delamination is a type of deterioration commonly found in concrete structures. It may form due to corrosion of embedded steel, poor construction, excessive vibration, or lack of bonding in composite construction. Impact ...
AN EXPERIMENTAL STUDY OF COUPLED THERMO-HYDRO BEHAVIOR IN UNSATURATED SOIL
(2020-08-25)
Understanding unsaturated soils in response to the impact of temperature will better predict the performance of geo-structures that extract and inject underground heat. Previous studies have shown that heat and water in ...
IMPACTS OF CONSTRUCTION MATERIAL DELAY IN IRAQ
(2020-01-06)
The construction industry is considered one of the most important industries in Iraq. It is well known that most construction projects in this country can experience missed deadlines and cost overruns or both. The main ...
LABORATORY STUDY OF HYDRODYNAMICS OF SUBMERGED BRIDGES
(2020-12-08)
Bridges are designed to withstand flood and debris loads; however, it is reported that 53% of bridge failures in the U.S. are caused by hydraulic events, including floods, scour, debris, and drifts. A series of scale flume ...
HYDROLOGIC & HYDRAULIC ANALYSES TO RE-ESTABLISH TRIGG BRANCH’S JURISDICTIONAL CHANNEL TO PRE-DAM CONDITION USING HEC-HMS & HEC-RAS MODELS
(2020-12-08)
Birds strikes are the most prevalent cause of airplanes strikes, and retention ponds
near airports are one of the most attractive spots for both immigrant and domestic
wildlife USDA (2017). Since the Trigg Lake, water ...
DEVELOPING STRENGTH REDUCTION FACTOR FOR FLEXURAL DESIGN OF REINFORCED CONCRETE BEAMS EXPOSED TO FIRE
(2020-12-17)
Fire is a common hazard that may happen during the lifetime of concrete structures. Thus, it is one of the loads considered in building and tunnel design standards and codes. Dependency of the safety and structural integrity ...
EXPERIMENTAL INVESTIGATION OF ANCHOR GROUP EFFECTS ON CONCRETE BREAKOUT STRENGTH WITHIN FIBER REINFORCED CONCRETE
(2020-12-07)
This research investigates the effect of anchor groups on concrete breakout strength within steel fiber reinforced concrete (SFRC) under tension load. High strength steel headed studs (F1554 Grade 105) in grouping action ...
Optimization of Primary Chemical Feed Rates and Application Points at an Existing Potable Water Treatment Plant
(2023-06-05)
Due to a major upset in the treatment processes for the Dallas County Park Cities Municipal Utility District caused by a required change in treatment techniques, an optimization study was conducted to find the best treatment ...
Application of Photogrammetry for Monitoring Soil Surface Movement
(2023-05-19)
Understanding slope behavior and forecasting failure requires accurate soil surface movement measurements. Research gaps and constraints remain despite the development of diverse methods. Recently, photogrammetry has become ...
FURTHER DEVELOPMENT OF ULTRA-HIGH-PERFORMANCE FIBER REINFORCED CONCRETE (UHP-FRC): 3D PRINTING, SIFCON, ALTERNATIVE FIBERS, SHRINKAGE CRACK CONTROL, HIGH TEMPERATURE, AND LIGHTWEIGHT
(2021-08-10)
Introduction of artificial intelligence (AI) and machine learning in manufacturing industry also in every service industry, decreasing conventional skilled workforce and stagnated construction industry, probability and ...
