Book Description
Inelastic design of steel girder bridges offers the potential for significant cost savings because it accounts for the true strength of the bridge, which is often considerably above that predicted by the elastic or pseudo-plastic procedures used in present bridge specifications. However, current inelastic design procedures are only applicable to bridges comprising compact sections. The objectives of this research are to (1) propose new comprehensive and practical inelastic design procedures that allow compact and noncompact sections, (2) experimentally verify inelastic limit state behavior with large-scale continuous span tests of composite girders, and (3) examine the moment-rotation behavior of compact and noncompact pier sections. The strength and permanent-deflection limit states used in the LRFD inelastic design bridge specifications are summarized, and new simplified inelastic procedures that satisfy these limit states are proposed. Shakedown is appropriately used to define strength under moving loads. The permanent-deflection limit state can be satisfied either by limiting positive-bending stresses after inelastic redistribution of moments or by limiting calculated permanent deflections directly. The simplified procedures proposed to satisfy the two limit states apply to both compact and noncompact sections. They utilize elastic moment envelopes and do not require successive loadings, iterative procedures, or simultaneous equations. Corresponding provisions and commentary that could be incorporated into the LRFD bridge specifications are presented. Experimental testing of continuous span girders and girder components were conducted to verify inelastic design limits and investigate inelastic behavior. A compact three span composite girder and a noncompact two-span composite girder were tested subjected to simulated moving truck loads. Experimental results are compared to design limit states, along with discussion on general inelastic behavior. The results from the tests performed in this project support the development and verify the procedures of the proposed LRFD inelastic design provisions for bridges comprising noncompact girders. The limit state design levels were satisfied and the overall behavior of the girders met expectations.

ISBN: 0470085258
Category : Technology & Engineering
Languages : en
Pages : 1120
Book Description
The definitive guide to stability design criteria, fully updated and incorporating current research Representing nearly fifty years of cooperation between Wiley and the Structural Stability Research Council, the Guide to Stability Design Criteria for Metal Structures is often described as an invaluable reference for practicing structural engineers and researchers. For generations of engineers and architects, the Guide has served as the definitive work on designing steel and aluminum structures for stability. Under the editorship of Ronald Ziemian and written by SSRC task group members who are leading experts in structural stability theory and research, this Sixth Edition brings this foundational work in line with current practice and research. The Sixth Edition incorporates a decade of progress in the field since the previous edition, with new features including: Updated chapters on beams, beam-columns, bracing, plates, box girders, and curved girders. Significantly revised chapters on columns, plates, composite columns and structural systems, frame stability, and arches Fully rewritten chapters on thin-walled (cold-formed) metal structural members, stability under seismic loading, and stability analysis by finite element methods State-of-the-art coverage of many topics such as shear walls, concrete filled tubes, direct strength member design method, behavior of arches, direct analysis method, structural integrity and disproportionate collapse resistance, and inelastic seismic performance and design recommendations for various moment-resistant and braced steel frames Complete with over 350 illustrations, plus references and technical memoranda, the Guide to Stability Design Criteria for Metal Structures, Sixth Edition offers detailed guidance and background on design specifications, codes, and standards worldwide.
