New submissions to the thesis/dissertation collections are added automatically as they are received from the Graduate School. Currently, the Graduate School deposits all theses and dissertations from a given semester after the official graduation date. This means that there may be up to a 4 month delay in the appearance of a give thesis/dissertation in DRUM

    RESPONSE OF FOUNDATIONS SUBJECTED TO VERTICAL DYNAMIC LOADING
    (2015) Sutaih, Ghassan Hassan; Aggour, Mohammed S; Civil Engineering; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    Design of machine foundations that are subject to dynamic loading require that their amplified displacement is within certain limit so that such displacement doesn’t impede the operation of the machine they are supporting. For the design of such foundations, several methods are available that are based on a mathematical solution of the differential equation that represents dynamic loads on an elastic half space. When the soil conditions are not uniform, the response cannot be predicted accurately by these methods and hence numerical methods should be used to analyze the problem. This research presents a numerical solution to a foundation subject to dynamic loading considering: 1) the effect of soil layering on the dynamic response. Specifically, a footing rests on a finite soil layer over an elastic half space and 2) the effect of the depth of embedment of a foundation in a homogenous elastic half space on its dynamic response
