The increasing environmental concerns in the world today have caused us all to examine the way we live. These issues have affected every aspect of our lives, including the materials we use in construction.
The use of cold-formed steel members as a building alternative is an intelligent choice with benefits to, not only the environment, but also to the contractor, designer and developer.
Steel is not only a recyclable product, but also a stronger product allowing for longer clear-spans in the design process. Cold-formed steel is lighter providing ease of handling. It is a straighter product giving a “true” wall with which to work. It doesn’t suffer fluctuation in price, making it easier to bid a project. Quality control is stressed in all phases of the manufacturing process so the highest possible quality is delivered to the job site.
The structural shapes manufactured are easily used for non-structural and structural assemblies, floor and ceiling joist assemblies, and panelized systems. They can be used as the main structural support system or as a supplement to heavy structural steel or concrete construction.
Manufacturers have been producing cold-formed steel framing members for many years, with each manufacturer having its own nomenclature and design values. A steel member with identical properties would be identified by different names based on which manufacturer produced it. This created some confusion at all levels of the construction process.
The SSMA's mission is to proactively represent member firms engaged in the manufacture, marketing and sale of cold-formed steel framing members, as a unified voice to the residential and light commercial
construction industry serviced by its products, which includes contractors, distributors, design professionals, code officials and standards organizations. To this end, SSMA will endeavor to supply products which meet or exceed standards established by national, state and local code bodies and by
recognized industry associations. SSMA resolves to continually initiate and adopt the development of new technology and applications for its members' products with the common goal of growing new market opportunities.
Code Approval
Products manufactured by the members recognized by ICBO Evaluation Service of the Steel Stud Manufacturers Association, SSMA, comply with the Uniform Building Code and International Building Code. See ICBO ES Evaluation Report No. 4943-P.
Material Specifications
Products manufactured by SSMA members are formed from steel with a minimum yield stress of 33 ksi or 50 ksi. All products covered in this catalog are engineered to meet the 1996 Edition of the American Iron and Steel Institute, AISI, “Specification for the Design of Cold-Formed Steel Structural Members.” The structural properties included in this brochure have been computed based on allowable stress design to conform with the same AISI document.

This reference presents the classical perspectives that form the basis of heat treatment processes while incorporating descriptions of the latest advances to impact this enduring technology. The second edition of the bestselling Steel Heat Treatment Handbook now offers abundantly updated and extended coverage in two self-contained volumes: Metallurgy and Technologies and Equipment and Process Design.
Continuing the tradition of the first edition, this comprehensive reference integrates metallurgical principles with engineering technology in terms of basic process, equipment operation, and design.Up-to-date references, new topics, and rewritten chapters bring additional breadth, depth, and clarity to process design for heat treatments. This second edition presents unique and timely coverage of treatments for tool steels, stainless steels, and powder metallurgy components. The book also contains new material on vacuum processes, designing quench processes, steel transformation mechanisms, updated nomenclature and classifications, nitriding techniques, metallurgical property testing, and distortion of heat-treated components.
Steel Heat Treatment Handbook, Second Edition provides a well-rounded resource for everyday use by advanced students and practitioners in metallurgy, process design, heat treatment, and mechanical and materials engineering.

A unique book-and-DVD package from preeminent programming instructor Rod Stephens
Visual C# has become a leading programming language, resulting in greater career opportunities for Visual C# programmers. This Wrox guide literally shows novice programmers how to program in C# with Microsoft Visual Studio, using both written and visual instruction.
Easy-to-follow lessons reinforced with step-by-step instructions, screencasts, and supplemental exercises make it easy to master Visual C# programming regardless of your learning style. Each lesson begins with a discussion of a concept or technique and proceeds through step-by-step directions for using the technique Visual C# has surpassed Visual Basic as the most popular programming language
* This book-and-DVD package provides an introduction to Visual C# programming, with screencasts on the DVD to support each lesson in the book
* Each lesson includes a "Try It" section with exercises for developing a programming solution, goals for the exercise, and pointers about handling more complex issues
* DVD shows how the author works through each lesson in the book
Stephens 24-Hour Trainer: C# Programming with Visual Studio 2010 teaches Visual C# in the clear, compelling style for which Rod Stephens is famous.

PUSHOVER ANALYSIS : Why , How, When, and When Not to Use It
The static pushover analysis is becomea popular method of predicting seismic force and deformation demands for the purpose of performance evaluation of existing and new structures. If applied thoughtfully and with good judgment, it will provide much useful information that cannot be obtained from elastic static or dynamic analysis procedures. However, the method is based on many assumntions that may provide misleading results in some case. thus, the pushover need to be viewed as an engineering tool with much potential, but with pitfalls that have to be recognized in order to avoid gross misinterpretations. This paper points out some of these pitfals, but its main focus is a general discussion on the pushover's advantages (why to use it ), background and implementation (how to use it), and applications(when to use it).
