Final Design Report: Vibration Table For Cvbt- Vt4 Design Team, Thomas Bevan, Matthew Laurino

Mechanical Engineering

CVBT (Center for Vocational Building Technology) teaches villagers in Northeastern Thailand how to make various concrete products. Many of these products require the use of a vibration table in order to remove air and water trapped within the concrete. Removal of these voids improves the outside surface of the molded concrete, and also allows the use of a lower water to cement ratio, allowing a much stronger finished product. The currently used vibration table (VT3) has several disadvantages associated with it, which the new table (VT4) eliminates. Compared with the VT3, the VT4 has a more rigid tabletop and improved …

Flexural Behavior Of Spun Concrete Poles Reinforced With Glass Fiber Reinforced Polymer (Gfrp), Sally Palmer

All ETDs from UAB

Steel-reinforced structural concrete has been used in civil engineering practice for many years. A primary concern with steel-reinforced structural concrete is corrosion. In marine environments, corrosion becomes an important factor and may impact the long-term durability of the conventional steel-reinforced structure. Concrete poles are commonly placed in severe marine or industrial environments that are conducive of corrosion. Traditionally, these poles are reinforced with steel material, which poses the certainty of corrosion and deterioration. Recently, various alternatives to the use of steel reinforcement have been studied. Alternative non-metallic reinforcement will increase the lifespan of the product, reduce maintenance needs, and result …

Performance Of Reinforced Concrete Columns Strengthened With Fiber Reinforced Polymers Under Various Loading Conditions, Mohamed Gamal Mohamed El Sayed

Theses

Strengthening of reinforced concrete (RC) structures with Carbon Fiber Reinforced Polymer (CFRP) composites has been a popular subject that attracted considerable attention from researchers for the last two decades. The high specific strength, stiffness, environmental resistance, and ease of application make CFRP composites highly desirable for strengthening and rehabilitation of RC structural components.

For concentrically loaded RC members with a circular cross-section, the lateral CFRP-confinement of concrete results in a substantial increase in load capacity and ductility. CFRP-confinement is less effective for RC compression members with square and rectangular cross-sections due to stress concentration at the corners and lack of …
