Theorizing Communication: Readings Across Traditions is the first collection of primary-source readings built around seven traditions of communication theory- rhetorical, semiotic, phenomenological, cybernetic, sociopsychological, sociocultural, and critical.. The selected readings illustrate the history of each tradition and current trends. Enhancing the readings are introductory essays and sets of projects for theorizing through which the editors highlight contemporary interpretations, new directions, and/or hybrid approaches to studying communication theory. Key Features: Includes key primary source readings that have helped to define the field of Communication Theory: This collection of readings is not available elsewhere and frees instructors from having to design their own course packs. Offers a comprehensive view of communication theory by not limiting content to a single approach: This book is the first collection of readings on communication theory based on Robert T. Craig
Rigidly Framed Earth Retaining Structures : Thermal soil structure interaction of buildings supporting unbalanced lateral earth pressures (9783642546426)
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.
