[EAN: 9781408622391], Neubuch, [PU: Lee Press], Architecture|General, History|United States |General, History|Historical Geography, BRAND NEW PRINT ON DEMAND., High Masonry Dams, John Bach McMaster, HIGH MASONRY DAMS - 1876 - PREFACE - In the preparation of the following treatise three points have been constantly in view, to avoid as far as possible all purely theoretical discussion, to discover the most economical forms of profiles consistent with perfect strength, and to consider none that have not, after repeated practical application demonstrated their excellence, even under thc severest tests. To treat the subject, however, in a logical way, it has been found best to begin with a theoretical determination of the strongest and at the same time least expensive form of profile, and afterwards to modify this to meet the requirements that arise in actual construction. The theoretical type is, as I have attempted to show, that composed of a vertical face on the inner, and a concave surface on the outer side. Of this, there are, of course, an almost unlimited number of possible modifications. But when we impose the condition of ewnmny, the number of really useful ones dwindle down to less than half a dozen. Those treated of in the present work number four. The first illustrated in Fig. g, is, beyond all doubt, the I very best. It has indeed, been often urged against this type of profile, that it is difficult to determine with accuracy the equations of the logarithmic curves forming the bounding faces, as also to cut the facing stones to such a curve. As to the first objection, no equations can surely be simpler than those we have given, while the second is a difficulty most easily removed, not by argument, but by determination. The three other types are also profiles of equal resistance, and are treated of so fully in the work as to call for no remark here. It will also be observedthat I have touched very lightly on the sliding of dams on trheir foundation, or of any portion of them along a horizontal joint. This has been done, because, though I have examined as fully as possible the causes that have led to the destruction of dams of all style of profile and of all heights, both abroad and in thG country, I have been able to find extremely few that ay justly be said to have yielded by. sliding. It has almost invariably been by revolving about an axis near the outer face, caused by taking too great a limit of vertical pressure, and thus throwing the line of resistance, when full, too far outward from the centre of thickness. JOHN B. McMASTER. NEW YORK, February, 1876. - HIGH MASONRY DAMS, THE subject proposed for consideration in the following work is that of the profile of masonry dams of such height, breadth and general dimensions as would be required for reservoir purposes, or for impounding the waters of rivers and large streams for mill or irrigation use. We would observe, however, at thc outset, that as this matter has already been treated with R U C fu llness by several writers, and especially by MM. Delocre and Sazilly-to whose excellent memoirs we are greatly indebted-we can hope to add little that is really new, but shall endeavor, by drawing from many sources, to supply our own deficiency, to diminish the errors of others, and thus obtain results very much more accurate than could be derived if we relied solely on ourselves. Before, however, we take up the consideration of the matter of the form of profile that shall combine the greatest strength with the least amount of material, there are a number of important points to be considered somewhat in.detail.<
