Models for flexural cracking in concrete; the state of the art by
A. Borosnyoi and G. L. Balazs
Structural Concrete, 2005 - 6 No 2
Crack formation presents a complex mechanical and geometrical question to be modelled. The available crack
width formulations are often based on simplifications. A rigorous formulation of crack widths should be based on
the integration of strain differences of reinforcement and concrete between cracks, due to the accumulated slips.
In this paper an extensive literature review on crack widths and crack spacing is presented. The basic intention of
the present paper is to summarise the development of flexural crack models and collect the most relevant formulae
for crack spacing and crack width. It reports not only the possible improvement of design or research equations but
also the appearance of new types of reinforcements with different characteristics from those of steel
reinforcements. This state-of-the-art Report is a contribution to the work of fib TG 4.1 ‘Serviceability Models’.

Seismic Design of Reinforced Concrete Mat Foundations
Author: Ron Klemencic, Ian S. McFarlane, Neil M. Hawkins, Sissy Nikolaou | Size: 2.01 MB | Format:PDF | Quality:Original preprint | Publisher: NEHRP Consultants Joint Venture, Applied Technology Council (ATC) and the Consortium of Universities for Research in Earthquake Engineering (CUREE) | Year: 2012 | pages: 33
Seismic design of reinforced concrete mat foundations has advanced significantly in the last twenty years. As analytical capabilities have improved, primarily in the form of finite element analysis, the mathematical modeling of these continuous structural elements has led to seemingly more precise designs. Yet, fundamental questions still remain regarding the seismic performance of these thick foundation
systems.
This Technical Brief attempts to address what is known and what is unknown about this subject, so that a structural engineer can proceed with a seismic design in an informed manner. Because many of the parameters associated with a mat foundation design can be highly variable, designs that consider this variability are encouraged.

SOIL NAILING FIELD INSPECTORS MANUAL -- SOIL NAIL WALLS
Author: Porterfield, J A Cotton, D M Byrne, R J | Size: 5.92 MB | Format:PDF | Quality:Original preprint | Publisher: Golden Associates, Incorporated | Year: 1994 | pages: 115
The purpose of this manual is to provide field inspectors with the knowledge necessary to effectively monitor and document the construction of soil nail retaining walls. The manual provides information useful to both the experienced and inexperienced soil nail inspector. The manual is organized into two main parts: Preconstruction Preparation and Construction Inspection. Checklists are provided throughout the Construction Inspection sections of the manual which summarize key items discussed in the text. The inspector is encouraged to copy the checklists for use during construction. Appendix A contains blank forms that can be used for proper documentation and testing during soil nail wall construction. Appendix B contains examples of completed forms. Construction inspectors and engineers from California, Oregon, Texas, and Washington State departments of transportation contributed to this manual. The International Association of Foundation Drilling also provided input from the industry perspective.

Geotechnical Engineering Circular No. 3:
Design Guidance: Geotechnical Earthquake Engineering for Highways,
Volume II - Design Examples
Author: Kavazanjian Jr, E Matasovic, N Hadj-Hamou, T Sabatini, P J | Size: 7.82 MB | Format:PDF | Quality:Original preprint | Publisher: GeoSyntec Consultants | Year: 1997 | pages: 182
This document presents a series of five design examples illustrating the principles and methods of geotechnical earthquake engineering and seismic design for highway facilities. These principles and methods are described in Volume I - Design Principles, FHWA-SA-97-076. The examples presented in this volume cover a wide range of problems encountered in geotechnical earthquake engineering practice. The design examples presented in this document include: seismic design of a shallow bridge foundation; seismic design of a driven pile bridge foundation; seismic design of a gravity retaining wall based on results of a detailed seismic hazard analysis; seismic slope stability analysis of a cut slope in soft rock; and liquefaction potential analysis.
