Available in PDF, EPUB and Kindle. Book excerpt: Today's bridges are being constructed with longer spans and higher girder spacing. As a result, the use of precast prestressed concrete modified bulb tee (MBT) girders has significantly increased. The MBT girders have a wider and thinner top flange than other conventional precast concrete cross-sections. The strength of the thin top flange has been identified as a concern for the North Carolina Department Of Transportation when edge of flange falsework hangers are used to support the overhang deck slab falsework system. In response to theses concerns, the NCDOT has funded research project 2005-18 "Full Scale Testing of Overhang Falsework Hangers on NCDOT Modified Bulb Tee (MBT) Girders" to study the behavior of the edge of flange falsework hanger systems. Standard falsework hangers manufactured by Dayton/Richmond and Meadow/Burke were tested as a part of this research. This research consists of two parts, the experimental and analytical investigations. The effects of amount of the shear reinforcement, the effect of the adjacent loaded hangers and the type of hanger were investigated in the experimental investigation. The finite element models were generated to predict the behaviors of the falsework system such as the limit state, ultimate load, and the response of the system. From the experimental result, the ultimate load of both hanger types, Dayton/Richmond and Meadow/Burke did not reach the ultimate strength provided by manufacturer. The Dayton/Richmond and Meadow/Burke hangers failed approximately 75% and 55% of the manufacturer ultimate strength by the spalling of the concrete under the hanger and punching shear failure. There were effects of the shear reinforcement and the adjacent loaded hanger observed. From the results of finite element models, the initial stiffness of the applied hanger load and deflection at mid-span of the model was higher than the experimental results. The models predicted failure by flexural cracking and punching shear for the Dayton.

This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Bulb Tee girders provide a practical, efficient means of spanning the large distances required in today's bridge designs by utilizing large moments of inertia to withstand the massive moments created in the spans. A bulb tee girder possesses a wider, thinner top flange than conventional precast concrete cross-sections. Previous research suggests the thin top flange of an exterior bulb tee girder in the bridge deck overhang falsework system to fail in punching shear and concrete bearing/spalling at premature loads. Meadow Burke Products, Inc. has manufactured an innovative falsework hanger for use with thin flange girders such as the bulb tee. The hanger utilizes a bearing plate to distribute the vertical loads on the top flange. Experimental full scale testing of the innovative hanger on a bulb tee girder was completed as the first phase of this study. The hangers were installed onto a 63 in. North Carolina Department of Transportation (NCDOT) Modified Bulb Tee (MBT) girder and loaded by a hydraulic load cylinder at a 45 degree angle. The behavior and ultimate strength of the hanger and top flange of the girder were recorded. Phase two of the experimental study consisted of testing the overhang falsework system with support brackets attached to the Meadow Burke hangers. The support brackets were loaded vertically utilizing hydraulic load cylinders. The load distribution behavior of the bracket and ultimate loading capacity of the system were recorded. Both phases of the experimental study concluded that a punching shear failure will occur in the top flange of the girder at a consistent loading. Subsequent analytical studies were carried out in an attempt to predict and emulate the results seen in the experimental testing. The analytical study consisted of finite element models and ACI code provisional analysis for punching shear. The finite element models developed are able to accurately predict the behavior and ultimate strength of the system. ACI code for punching.

Download or read book Steel Plated Structures written by M. Ivanyi and published by Springer. This book was released on 2014-05-04 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume strives to give comprehensive information about the main aspects of the behaviour and limit states of steel plated structures. In following this objective, the volume presents a complete scientific background (profiting from the fact that the authors of the individual parts of the publication have personally been very active in the corresponding fields of research for an extended period of time), but also establishes design recommendations, procedures and formulae. The significance of the volume may be seen in its challenging current concepts of the analysis of steel plated structures, encouraging progress in the field, and thereby establishing an advanced basis for a more reliable and economical design.
Download or read book Baroque and Rococo Art and Architecture written by Robert Neuman and published by Prentice Hall. This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Baroque and Rococo Art and Architecture is the first in-depth history of one of the great periods of Western art, spanning the years 1585 to 1785. The text treats the major media-painting, sculpture, drawings, prints, and architecture-as well as gardens, furniture, tapestries, costume, jewelry, and ceramics, all in terms of their original function and patronage and with emphasis on the social, political and cultural context. Organized by country and medium, the book contains biographies of the leading creative figures of the time, from Caravaggio and Rembrandt to Watteau and Hogarth. Significantly, Professor Neuman offers the fullest account to date of women artists and the representation of women and families in art. Additionally, drawing from recent scholarship, the text explores such fields as Spanish polychrome sculpture and Viceregal American painting. Baroque and Rococo Art and Architecture reviews traditional and recent strategies for interpreting artworks. It also traces the dissemination of visual ideas through prints and drawings-the forerunners of today's art reproductions and digital media. In special sections the text raises questions regarding the nature of perception and how artists transfer optical data to the canvas. Artists' techniques, from painting and printmaking to sculpting in marble and casting in bronze, are explained. Analysis of the institutions of art, such as the royal academies, apprenticeship systems, and artists' exhibition rooms, complements an examination of collecting at all levels of society. The book is exceptional in considering issues related to authenticity and the relative value of artworks based on attribution. The illustrations comprise a visual resource of unprecedented quality, with some 450 images reproduced in full color and in a large format that ensures high detail and emphasizes recent conservation efforts. Finally, an extensive glossary introduces seventeenth- and eighteenth-century art terms.
