PART (PROPERTIES OF STRUKCTURAL STEEL) 1 :
This section presents and discusses the properties of structural steels that are of importance in design and construction. Designers should be familiar with these properties so that they can select the most economical combination of suitable steels for each application and use the materials efficiently and safely.
PART 2 (FABRICATION & ERECTION) :
Designers of steel-framed structures should be familiar not only with strength and serviceability requirements for the structures but also with fabrication and erection methods. These may determine whether a design is practical and cost-efficient. Furthermore, load capacity and stability of a structure may depend on design assumptions made as to type and magnitude of stresses and strains induced during fabrication and erection.
PART 3 (GENERAL STRUCTURAL THEORY) :
Safety and serviceability constitute the two primary requirements in structural design. For a structure to be safe, it must have adequate strength and ductility when resisting occasional extreme loads. To ensure that a structure will perform satisfactorily at working loads, functional or serviceability requirements also must be met. An accurate prediction of the behavior of a structure subjected to these loads is indispensable in designing new structures and evaluating existing ones.
The behavior of a structure is defined by the displacements and forces produced within the structure as a result of external influences. In general, structural theory consists of the essential concepts and methods for determining these effects. The process of determining them is known as structural analysis If the assumptions inherent in the applied structural theory are in close agreement with actual conditions, such an analysis can often produce results that are in reasonable agreement with performance in service.
PART 4 (ANALYSIS OF SPECIAL STRUCTURE) :
The general structural theory presented in Sec. 3 can be used to analyze practically all types of structural steel framing. For some frequently used complex framing, however, a specific adaptation of the general theory often expedites the analysis. In some cases, for example, formulas for reactions can be derived from the general theory. Then the general theory is no longer needed for an analysis. In some other cases, where use of the general theory is required, specific methods can be developed to simplify analysis.
This section presents some of the more important specific formulas and methods for complex framing. Usually, several alternative methods are available, but space does not permit their inclusion. The methods given in the following were chosen for their general utility when analysis will not be carried out with a computer.
PART 5 (CONNECTIONS) :
In this section, the term connections is used in a general sense to include all types of joints in structural steel made with fasteners or welds. Emphasis, however, is placed on the more commonly used connections, such as beam-column connections, main-member splices, and truss connections.
Recommendations apply to buildings and to both highway and railway bridges unless otherwise noted. This material is based on the specifications of the American Institute of Steel Construction (AISC), ‘‘Load and Resistance Factor Design Specification for Structural Steel Buildings,’’ 1999, and ‘‘Specification for Structural Steel Buildings—Allowable Stress Design and Plastic Design,’’ 1989; the American Association of State Highway and Transportation Officials (AASHTO), ‘‘Standard Specifications for Highway Bridges,’’ 1996; and the American Railway Engineering and Maintenance-of-Way Association (AREMA), ‘‘Manual,’’ 1998.
