Book excerpt: "Expanded polystyrene (EPS) geofoam has been increasingly used in geotechnical engineering applications either as lightweight fill material or as compressible inclusion to reduce earth pressure on earth retaining structure under both static and dynamic loading. These applications involve the installation of geofoam blocks in direct contact with other materials (e.g. steel, soil, concrete etc.) forming a composite structure. In this thesis an attempt has been made to experimentally determine shear strength of monoblock of EPS geofoam and interface strength of geofoam interacting with different materials. Further, numerical studies are carried out to investigate the role of EPS geofoam in reducing lateral earth pressure on rigid non-yielding retaining walls under static and dynamic loading conditions. First, a series of direct shear tests has been conducted on geofoam samples of three different densities, namely, 15 kg/m3, 22 kg/m3 and 39 kg/m3 under three different normal stresses 18, 36 and 54 kPa. In addition, interface shear tests are also conducted to determine the interface strength parameters as these geofoam blocks interact with selected materials (e.g. PVC, sand, concrete, steel, wood). Test results revealed that geofoam density and applied normal stress have significant effects on the vertical compression and interface strength properties. Next, a 2D plane strain finite element model is developed to investigate the effectiveness of EPS geofoam in reducing static earth pressure on rigid retaining wall. Numerical model is first validated with the results of physical tests. A parametric study is then carried out to investigate the role of EPS geofoam density, relative thickness and backfill frictional properties on reduction of static lateral earth pressure on the wall. Three different geofoam samples having three different thicknesses interacting with four different backfill soils were used in this study. Finally, a 2D plane strain finite element model is developed to study the role of EPS geofoam in reducing seismic earth pressure. Numerical model is first validated against the results of reduced scale shaking table tests. A numerical parametric study is then conducted to investigate the effectiveness of EPS geofoam density, relative thickness and backfill frictional properties on reduction of seismic earth pressure on the rigid retaining wall. Four different geofoam samples having three different thicknesses interacting with four different backfill materials are used in this study. The results of numerical studies are presented in the form of design charts for practical implication"--

Download or read book Rigidly Framed Earth Retaining Structures written by Walid Aboumoussa and published by Springer. This book was released on 2014-06-23 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: Structures placed on hillsides often present a number of challenges and a limited number of economical choices for site design. An option sometimes employed is to use the building frame as a retaining element, comprising a Rigidly Framed Earth Retaining Structure (RFERS). The relationship between temperature and earth pressure acting on RFERS, is explored in this monograph through a 4.5 year monitoring program of a heavily instrumented in service structure. The data indicated that the coefficient of earth pressure behind the monitored RFERS had a strong linear correlation with temperature. The study also revealed that thermal cycles, rather than lateral earth pressure, were the cause of failure in many structural elements. The book demonstrates that depending on the relative stiffness of the retained soil mass and that of the structural frame, the developed lateral earth pressure, during thermal expansion, can reach magnitudes several times larger than those determined using classical earth pressure theories. Additionally, a nearly perpetual lateral displacement away from the retained soil mass may occur at the free end of the RFERS leading to unacceptable serviceability problems. These results suggest that reinforced concrete structures designed for the flexural stresses imposed by the backfill soil will be inadequately reinforced to resist stresses produced during the expansion cycles. Parametric studies of single and multi-story RFERS with varying geometries and properties are also presented to investigate the effects of structural stiffness on the displacement of RFERS and the lateral earth pressure developed in the soil mass. These studies can aid the reader in selecting appropriate values of lateral earth pressure for the design of RFERS. Finally, simplified closed form equations that can be used to predict the lateral drift of RFERS are presented.
