Comparative Study of Surface Preparation And Bond Angle Combinations For Bridge Repair Using Ultra-High Performance Concrete Alternative
Coleman, Raina (2018-12)Ultra-high performance concrete (UHPC) is a type of concrete with advanced mechanical properties compared to normal strength concrete and that can be used for connections and repairs in bridges. Most UHPC used in the field ... -
Design Guidance for Installing Vibration Sensitive Equipment in Industrial Facilities
Wise, Kevin (2016-08)The need to understand floor vibrations in an industrial facility has increased in recent years as the drive for tighter manufacturing tolerances has increased. This drive has led to an increase in manufacturing equipment ... -
Design of Continuity Connections for Precast, Pretensioned Girders Using Ultra-High Performance Concrete
Tiry, Zachary (2023-05-12)In recent years, an increased desire to improve the durability and resiliency of bridges has become an important consideration in design. Ultra-high performance concrete (UHPC) is a relatively new cementitious composite ... -
Designing and Characterizing Negative Stiffness Devices for Apparent Weakening and Vertical Isolation
Cain, Thomas (2020-05)Nonlinear systems leveraging the effects of negative stiffness can exhibit beneficial qualities for passive seismic mitigation in structures. Such systems can be achieved by placing nonlinear devices displaying negative ... -
Development Length of 0.6 in. Prestressing Strands in Precast, Prestressed Calcium Sulfoaluminate Cement Concrete
Bowser, Troy (2016-12-16)Calcium sulfoaluminate cement is a very rapid setting, hydraulic cement that releases approximately half as much carbon dioxide during production as conventional portland cement. Calcium sulfoaluminate cement produces ... -
Development of Non-Proprietary Ultra-High-Performance Concrete Mix Designs
McDaniel, Amy (2017-12)Ultra-High-Performance Concrete (UHPC) is defined by the Federal Highway Administration (FHWA) as having a compressive strength of 21.7 ksi (kilo-pounds per square inch), a post-cracking tensile strength 0.72 ksi, and high ... -
Effect of fiber content on tensile strength of non-proprietary ultra-high performance concrete
Campos, Richard (2020-12-18)Ultra-high performance concrete (UHPC) is being used to solve challenging concrete structural applications where conventional concrete would otherwise deteriorate and improved structural properties can be utilized. UHPC ... -
