Effects Of Supplementary Cementitious Materials On Early-Age Tensile Creep And Shrinkage Of Concrete, Lucas James Bucklen
Effects Of Supplementary Cementitious Materials On Early-Age Tensile Creep And Shrinkage Of Concrete, Lucas James Bucklen
Graduate Theses, Dissertations, and Problem Reports
Determination of early-age tensile creep properties is critical for the performance of mass concrete structures at an early age. Due to the stress relaxation that tensile creep induces in concrete structures, accurate quantification of creep deformation is needed to determine the stress profile of the structure. Conventional methods of measuring tensile creep include the direct tension test where the concrete is subject to constant tensile stress. This method requires large quantities of concrete with embedded strain gauges which can only be used once. In this paper, the tensile creep parameters of concrete are found by using the restrained concrete ring …
Large-Scale Modeling And Assessments Of Climate, Land Cover, And Sea Level Change Impacts On Stormwater Runoff In Coastal Urban-Natural Environments, Erfanul Huq
Graduate Theses, Dissertations, and Problem Reports
This dissertation investigated the potential impacts of changing climate, land cover, and sea level on the future stormwater budget and extreme runoff in coastal urban-natural environments. Two large-scale basins, namely Florida Southeast Coasts Basin (7117 km2) and Saint Johns River Basin (24928 km2), were selected for this study. The basins represented gradients in climate, land cover, and hydrology across the Atlantic coasts of Florida and the southeast U.S. Two mechanistic hydrologic models were developed for the basins using U.S. Environmental Protection Agency (U.S. EPA)’s Storm Water Management Model (SWMM) 5.1. The models were calibrated and validated with observed historical streamflow …
