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.

The following is a list of resources available for performance-based seismic design (PBSD) of buildings compiled by ACI Committee 374. The intention is to link this information to the ACI University website and the Committee 374 website, to provide a resource for ACI members to identify available guidelines, standards, and references for PBSD.

This document discusses commonly used cementitious materials for concrete and describes the basic use of these materials. It is targeted at those in the concrete industry not involved in determining the specific mixture proportions of concrete or in measuring the properties of the concrete. Students, craftsmen, inspectors, and contractors may find this a valuable introduction to a complex topic. The document is not intended to be a state-of-the-art report, user’s guide, or a technical discussion of past and present research findings. More detailed information is available in ACI 225R-99, “Guide to the Selection and Use of Hydraulic Cements,” ACI 232.2R-03, “Use of Fly Ash in Concrete,” ACI 233R-03, “Slag Cement in Concrete and Mortar,” and ACI 234R-06, “Guide for the Use of Silica Fume in Concrete.”

Aggregate properties and gradation significantly affect workability and finishability of freshly placed concrete and properties of hardened concrete including compressive strength, durability and abrasion resistance. Properties and accepted test methods discussed in this bulletin include: aggregate gradation; fine and coarse aggregate fineness moduli; relative bulk densities of wet, saturated surface dry, air-dry, and oven-dry aggregates; moisture absorption; shape angularity and surface texture; abrasion and impact resistance; permeability resistance to freeze thaw cycles and alkali-silica reaction; and chemical stability. Aggregate types including normalweight, lightweight and heavyweight natural aggregate; blast furnace slag aggregates; and recycled aggregates from crushed reclaimed concrete pavements are covered. Examples are provided on how to calculate and evaluate fineness modulus, batch mixture proportions adjusted for aggregate absorption, batch mixing water proportions, water cementitious ratios and bulk densities. Sampling aggregate methods to estimate average aggregate properties of large volumes or stockpiles, batches, or truckloads of aggregates are also covered.

Building codes based on the International Code Council International Building Code or adopting ACI Code 318 Building Code Requirements for Structural Concrete place the responsibility on the building official to ensure properly qualified personnel conduct tests and inspections and install products. A guide has been developed to aid the building official in determining the appropriate qualifications: Requirements for Building Official Approval of Personnel Conducting Special Inspections, Tests, and Installation of Concrete and Related Products. This guide is available as a free download as a resource for the building official. The guide only includes nationally recognized certification programs and is intended to be modified where appropriate local or regional certification programs exist. To facilitate the approval process, checklists included in the guide may be downloaded individually for use on each specific project, as needed: Checklist for Qualified Personnel Conducting Tests; Checklist for Qualified Inspectors; and Checklist for Qualified Installers.
