Structural Identification Of An Elevated Water Tower, James Thomas Norris
Structural Identification Of An Elevated Water Tower, James Thomas Norris
Graduate Theses and Dissertations
Elevated water tanks are generally located at higher elevations within a particular geographic area. The location and height of these structures often makes them desirable for installing wireless and cellular communications antennas. The impact of this practice on the long-term serviceability performance of the primary structure is not clear and could be an important consideration deserving further analysis. This paper presents a case study of an elevated water tank that was motivated by this particular consideration. The structure had been retrofitted with cellular antennas during its service and later experienced fatigue cracking at the fill pipe-tank interface. The owner wished …
Investigating The Bond Of Prestressing Strands In Lightweight Self-Consolidating Concrete, Royce Woodrow Floyd
Investigating The Bond Of Prestressing Strands In Lightweight Self-Consolidating Concrete, Royce Woodrow Floyd
Graduate Theses and Dissertations
Lightweight self-consolidating concrete (LWSCC) is a relatively recent advancement in concrete technology. The reduced dead load from lightweight concrete is beneficial for precast elements and for elements where dead load is a significant portion of the total load, such as prestressed bridge girders. Self-consolidating concrete (SCC) is a specially proportioned concrete mixture that consolidates under its own weight without the need for vibration. The combination of lightweight concrete and self-consolidating behavior provides the benefits of both. Bond of prestressing steel has been a much debated topic since the 1950s. Limited data are available on the transfer and development length of …
