Fumagalli, a work that covers both the development and present state of the art of structural model techniques. In my view, in this context, only a lack of understanding of the possibilities offered by experiments on models and sometimes an unjustified suspicion of them have up to now restricted the development that these methods deserve. I think, in particular, and the many examples quoted in the text bear witness to this, that models today constitute an efficient means of research that have been refined through advances in the methods of reproduction, testing and measurement. They represent a reliable and above all safe method of investigation, suitable for use in the elastic range and beyond up to failure, as much for historic ancient monuments as for modern works and structures of particularly bold design that are frequently highly redundant. They are a particularly valuable tool in areas where analytical methods are inadequate, and yet always useful for comparison with analytical results. Guido Oberti Preface I have embarked on writing a text on the techniques of structural models for two basic reasons: Firstly because I wish to attempt in some measure a personal appreciation of the subject based on more than twenty years experience, insofar as this can be achieved in a logically coherent and complete treatise.

Available in PDF, EPUB and Kindle. Book excerpt: Vibration tests were conducted on a 1:24-scale model of the North Fork Dam (Near Auburn, Calif.), a double-curvature arch dam, to determine natural frequencies, mode shapes, and hydrodynamic pressures. The mode shapes, natural frequencies, and hydrodynamic pressures were determined from tests using two-vibrators mounted on the crest of the dam. Hydrodynamic pressures at the dam-reservoir interface were also determined from tests in which the vibrator was attached to the downstream foundation of the dam. The hydrodynamic pressures calculated using Westergaard;s theory and a theory for arch dams developed by Perumalswami and Kar accurately predicted the measured pressure at frequencies below the first mode frequency of the dam. The differences in the two theories were insignificant. The accuracy of the Ritz analysis improved considerably as more nodes in flexible regions of the dam were loaded. However, the lowest eigenvalues were computed using the subspace iteration method. For the full reservoir, the natural frequencies decreased by 20-30% when the foundation was included in the finite element model. The difference was less when the reservoir was empty. The calculations using the subspace iteration scheme and including the foundation agreed closely with experimental mode shapes and corresponding natural frequencies.

This book was released on 2013 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document underscores various temperature related components and procedures for undertaking a successful performance analysis of concrete arch dams. Arch dams experience high temperature variations, which are generally assessed using finite element models. Deterioration of arch dams is caused principally by thermal effects, with 19% cases attributed to freezing and thawing, and 9% to temperature variations (Daoudu et al., 1997). The temperature loading conditions cause a high expanse of stresses at the various interface locations due to change in environmental conditions. Past research has shown that stresses caused by temperature change can be larger than those from reservoir loading (Bureau of Reclamation, 1977). The proposed finite element model for this study focuses on the performance assessment of arch dams in operation due to thermal loading.

This book was released on 2013-12-11 with total page 525 pages. Available in PDF, EPUB and Kindle. Book excerpt: Methods of controlling mass concrete temperatures range from relatively simple to complex and from inexpensive too costly. Depending on a particular situation, it may be advantageous to use one or more methods over others. Based on the author’s 50 years of personal experience in designing mass concrete structures, Thermal Stresses and Temperature Control of Mass Concrete provides a clear and rigorous guide to selecting the right techniques to meet project-specific and financial needs. New techniques such as long time superficial thermal insulation, comprehensive temperature control, and MgO self-expansive concrete are introduced. Methods for calculating the temperature field and thermal stresses in dams, docks, tunnels, and concrete blocks and beams on elastic foundations Thermal stress computations that take into account the influences of all factors and simulate the process of construction Analytical methods for determining thermal and mechanical properties of concrete Formulas for determining water temperature in reservoirs and temperature loading of arched dams New numerical monitoring methods for mass and semi-mature aged concrete
