This report demonstrates how statistical techniques can be used in the assessment of concrete structures to evaluate their condition and reliability and to assess the relative merits of possible repair options. A Reliability Toolkit provides licensed design professionals with a summary of some statistical methods that are useful for structural assessment. The report also gives two detailed examples of assessments for structural concrete repair.
Keywords:
confidence level; data analysis; durability; material properties; mean load method; rehabilitation; reliability; sample size; testing.

AutoRebar provides Autodesk AutoCAD (and all vertical products) with an extra toolbar with specific objects for rebar detailing of reinforced concrete structures.
With AutoRebar you can now quickly produce high quality drawings by automating the repetitive tasks previously involved in rebar detailing with plain AutoCAD. You can now focus on the conceptual part of the design rather than having to deal with time-consuming CAD editing work.
There are four types of dynamic objects: Rebars, Marks, Call-outs and the Bar Bending Schedule.
Rebar objects can be created and stretched like polylines and the bar size quickly edited with a double click. Since all AutoRebar entities are graphically connected, a modification to one or more Rebars causes all the linked objects to update automatically.
The user can add a new Mark by selecting the Rebar to be linked, and double click it to edit data such as the bar grouping criteria, the bar spacing and the size of the range; alternatively, normal AutoCAD® dimensions can be linked to the Mark and used to specify the range of a bundle of bars in the concrete structure; AutoRebar calculates the total number of bars in that range. The great thing is, whenever you modify the concrete shape and stretch the dimension, the total number of bars updates on the fly.
The Bar Bending Schedule can be either inserted in the drawing or exported to Excel with a simple click, while the EXPLODESEL and EXPLODEALL commands explode the AutoRebar objects into standard AutoCAD entities. This can be useful to deliver your drawing to other users who want to open and edit your drawing without having to install AutoRebar on their computers.

Foundation Engineering in the Face of Uncertainty, GSP 229, honors Fred H. Kulhawy, Ph.D., P.E., G.E., Dist.M.ASCE, for his many contributions advancing the science, art, teaching, and practice of geotechnical engineering. Dr. Kulhawy has influenced the civil engineering profession worldwide with his willingness to share his knowledge and expertise in many areas of geotechnical engineering including soil and rock mechanics, foundation engineering, and engineering geology.
This collection contains 54 papers that explore uncertainty in foundation engineering, including characterization of soil parameters, spatial variability, uncertainty and risk analyses, reliability analysis, and reliability-based design. Seventeen papers are reprints of classic papers authored or co-authored by Dr. Kulhawy, and 37 invited technical papers are contributions by experts from around the world, which also include informative case histories.
Foundation Engineering in the Face of Uncertainty contains practical and technical information on risk and reliability in foundation engineering that will be of interest to geotechnical engineers, foundation specialists, engineering geologists, and researchers.

Abstract: Over the last decade, hollow sections have enjoyed a dramatic rise in popularity as modern construction elements and are now used in numerous fields, including structural engineering, engineering, automotive manufacturing, and shipbuilding. Here, the authors, all renowned experts on this topic, have summarized their multifaceted experience in the field, making it available to the professional community. They have input both research results as well as their practical experiences.
The book covers the whole spectrum, starting with steel grades, via possible sections, and on to relevant norms, static and dynamic calculations, manufacturing, fire and rust protection, use in composites with concrete and even combinations with wooden sections. Example calculations round off the work.
The book will thus appeal to those in planning and engineering offices, experts in the field working in the construction industry as well as lecturers and students of steel construction
Modeling, analysis and design of bridge structures have been integrated into CSI Bridge to create the ultimate in computerized engineering tools. The ease with which all of these tasks can be accomplished makes CSI Bridge the most versatile and productive software program available on the market today.
Using CSI Bridge, engineers can easily define complex bridge geometries, boundary conditions and load cases. The bridge models are defined parametrically, using terms that are familiar to bridge engineers such as layout lines, spans, bearings, abutments, bents, hinges and post-tensioning. The software creates spine, shell or solid object models that update automatically as the bridge definition parameters are changed.
CSI Bridge design allows for quick and easy design and retrofitting of steel and concrete bridges. The parametric modeler allows the user to build simple or complex bridge models and to make changes efficiently while maintaining total control over the design process. Lanes and vehicles can be defined quickly and include width effects. Simple and practical Gantt charts are available to simulate modeling of construction sequences and scheduling.
CSI Bridge includes an easy to follow wizard that outlines the steps necessary to create a bridge model.
Completely integrated within the CSI Bridge design package is the power of the SAPFire analysis engine, including staged construction, creep and shrinkage analysis, cable tensioning to target forces, camber and shape finding, geometric nonlinearity (P-delta and large displacements), material nonlinearity (superstructure, bearings, substructure and soil supports), buckling and static and dynamic analysis. All of these apply to a single comprehensive model. In addition, AASHTO LRFD design is included with automated load combinations, superstructure design and the latest seismic design.
