  USDOT: Selection of Spread Footings on Soils to Support Highway Bridge Structures

Selection of Spread Footings on Soils to Support Highway Bridge Structures

[Image: 46251387885976525158.jpg]

[Image: info.png]
Selection of Spread Footings on Soils to Support Highway Bridge February 2010

Author(s)
Naresh C. Samtani, PE, PhD, Edward A Nowatzki, PE, PhD and
Dennis R. Mertz, PE, PhD

Abstract

The FHWA believes that spread footings on soils are underutilized because designers encounter one or more
of the following obstacles: (a) limited knowledge of AASHTO/FHWA technical references that pertain to
spread footings on soils to support bridges; (b) limited knowledge of adequate performance data for spread
footings; © unrealistic tolerable settlement criteria; (d) overestimation of loads used to calculate settlement;
and (e) the use of conservative settlement prediction methods. These obstacles have resulted in institutional
biases and overly conservative and excessively costly institutional processes that lead to the unnecessary use
of costlier deep foundation systems.
The primary goal of this report is to promote the use of spread footings bearing on competent natural soils,
improved soils, and engineered fill materials as a routine alternative to deep foundations for support of
bridges by addressing the factors identified above. Documented performance data is used to make this case.
The report also presents powerful concepts such as construction-point analysis and angular distortions to
demonstrate the efficacy of using spread footings. Implementation of these concepts requires only that
conventional computations be taken one step further without any requirement for advanced computational
skills. The report presents sources of information that agencies and designers can use as references in their
project applications. The report contains comprehensive appendices that treat in detail many of the topics
discussed in the report. For example, one such appendix provides an introduction to Load and Resistance
Factor Design (LRFD) that permits a rational approach to the consideration of spread footings on soils as a
feasible alternative to deep foundations

Design Aids In Soil Mechanics And Foundation Engineering

[Image: 31421565984592468392.jpg]

[Image: info.png]
Book: Design Aids In Soil Mechanics And Foundation Engineering
Author: Shenbaga R Kaniraj
ISBN:0074517147
ISBN-13: 9780074517147, 978-0074517147
Publishing Date: 2004
Publisher: Tata Mgraw Hill
Edition: 1st
Number of Pages: 514
Language: English

The book serves the interests and needs of designers, teachers and students of civil engineering. It provides the designers with specific design procedures and the relevant background material to understand the theory and methodology behind the procedures, their limitations and their relevance to the problem on hand. For teachers, this is a good resource book to teach more than one course in geotechnical engineering, both at the undergraduate and postgraduate levels. The students will find the book a good reference for several courses in geotechnical engineering and in their future professional career. The remaining part of the book, on soil engineering, covers all important problems typically met with in civil engineering practice. Applications of procedures are illustrated with numerous solved examples. Instances where the designer must use his own judgement are also brought out.

About the Author
Shenbaga R Kaniraj is presently Professor, Department of Civil Engineering Indian Institute of Technology, Delhi. He graduated in Civil Engineering in 1967 from PSG College of Technology, Coimbatore, then affiliated to the Madras University. He obtained an ME degree in Soil Mechanics and Foundation Engineering from the Indian Institute of Science, Bangalore, in 1969.

  Transportation and Traffic Theory: Flow, Dynamics and Human Interaction

Transportation and Traffic Theory: Flow, Dynamics and Human Interaction

[Image: 36142309180868875687.jpeg]

[Image: info.png]
Transportation and Traffic Theory: Flow, Dynamics and Human Interaction
Elsevier Science | July 12, 2005 | ISBN-10: 0080446809 | 800 pages | PDF | 70 mb

The ISTTT series is the main gathering for the world's transportation and traffic theorists, and the resulting volume is a field-defining milestone featuring the most promising thinking and theoretical developments. It reflects the major renewal the field is experiencing, with the entry of many new scientists from a variety of disciplines, and the mutual coexistence of a growing number of theoretical perspectives and modelling cultures.While this volume covers a wide range of aspects of the modelling of transportation processes as complex systems, an overarching theme is the recognition that these systems are a collective expression of individual human decisions. A significant number of the contributions published here therefore deal with some aspect of human behaviour - whether as travellers, drivers, passengers, operators, or regulators - reflecting the great strides being made in developing theories and mathematical representations of these phenomena.

  Theoretical Effective Length Factors for Cross-Braced Solid Round Diagonals
Posted by: yanburak - 09-04-2010, 09:03 AM - Forum: Civil Engineering MSc and PhD thesis - No Replies

Theoretical Effective Length Factors for Cross-Braced Solid Round Diagonals

[Image: 58599022860510155150.jpg]

[Image: info.png]
The objective of the investigation is to determine theoretically the effective
length factors of cross-braced solid round diagonals in all-welded steel
communication towers. Three beam-column models with different boundary
conditions (pinned, elastically restraked, and fixed) were investigated and it was
show that a beam-column with elastic restraints at ends and at cross-brace
location is the most accurate. However, for design purposes, when the ratio of
the diameter of the leg to the diameter of the diagonal exceeds three, beam-column
mode1 with fixed ends and elastic restraint at cross-brace location is
satisfactory. The theoretical results were compared with results of tests on 26
specimens.
