Bracing Cold-Formed Steel Structures: A Design Guide
Description
Prepared by the Committee on Cold-Formed Steel and the Committee on Metal of the Structural Engineering Institute of ASCE.
This report documents the current practices related to bracing cold-formed steel structure elements and systems. Heavy on applications and examples, this book contains design examples illustrating bracing design for various types of cold-formed steel structures, as well as an extensive list of primary reference sources.
Topics include:
•introduction to bracing design;
•cold-formed framing;
•cold-formed steel in metal building systems; and
•miscellaneous cold-formed steel elements and systems.
This report is presented as a design guide and will assist the practicing engineer in designing cold-formed steel structures with greater levels of reliability, safety, and economy.

Here I want to show the speed of NET 3.5 vs Intel Fortran.
I was amazing when I saw that NET application runs to fast versus Intel Fortran application.
I was used XP SP3, Visual Studio 2008 with NET 3.5 and Intel Fortran 11.1.067.
In both programs the same mathematical procedure is implemented. Solving of equations by Gauss elimination process.
The results for solving 1000 equations are:
computer: CPU2.6GHz, RAM 1.7GB, XP Sp3 NET 3.5 = 4.7sec
Intel Fortran = 16.8sec
Lahey Fortran = 7.2sec
Winner is NET application.
Maybe I made some mistake in Intel Fortran Compiler. Maybe I didn't include any optimization.
Here are source codes and executable files.

This publication has been developed to provide guidance as to how the direct displacement-based design methodology can be codified. It is intended for insertion within the seismic requirements of a code, establishing how design forces can be obtained using a Direct Displacement-Based Design (DDBD) approach. The document has currently been drafted with reference to several clauses of Eurocode 8. This document is presented in a traditional “Code + Commentary” format, on a split two-column page. The commentary aims to generally clarify the code requirements and indicate references where the background and further discussion on the requirements can be found. The document is the product of a 3-year Italian research initiative into the displacement-based design and assessment of structures as part of the RELUIS (Rete dei Laboratori Universitari di Ingegneria Sismica) project. The bulk of the text and requirements in this code have been developed from the recommendations provided in the book on DDBD by Priestley et al. (2007) and from the work carried out by the various research units of RELUIS Linea IV. Currently the model code has been prepared for a specific range of building structures and bridges. Given the limited range of structures that could be considered to date, the model code does not yet cover all structural systems and materials. In addition, a number of novel recommendations have been proposed that are preliminary in nature because of the limited amount of experimental or analytical data on which they are based. Future versions of this document will look to refine the current recommendations and extend the guidelines to encompass a more complete range of structural systems. With this in mind, the Model Code is published as a draft subject to public enquiry. Readers are kindly invited to provide feedback on the design recommendations by December 1st 2009. The bulk of the text and requirements in this code have been developed from the recommendations provided in the book on Direct Displacement-Based Seismic Design of Structures by Priestley et al. (2007). In fact, this Model Code was developed using Chapter 14 of the book as a starting point. The editors therefore wish to extend special thanks to the first author of the book, Nigel Priestley, for his invaluable contributions to this work, without which the Model Code would never have been possible.
I am a student from South Africa who studied towards a National Diploma in Civil Engineering. In other words Civil Technician. Some of you might know it is pretty hard to assure yourself a good future in South Africa. You really have to walk into the right opportunities to make something of yourself in this country. So I finished my diploma and was under the impression I will at least make enough money to enjoy life a bit. After rent, food, car installment and a bit of party over the weekends you having nothing left of your salary.
What can I do as a Civil Technician to assure myself a better future? I am working at a consulting firm at the moment. I must be honest I don't get a lot of experience here and bigger companies doesn't want to hire because you don't have the required experience. Feels like my hands are tied here. If anyone got some good advice I would appreciate it. I am busy with my B-tech to become a technologist. Hopefully that will help a bit. Which other short courses can I do that will help me a lot? Autocad for example?
I'm a new member here. I just wonder any GURU out here who are very experience in estimating steel tonnage for building.
For example contractor will do estimation of total steel tonnage of a factory base on architect layout, say 15ton/m² etc. inclusive column, rafter, etc. Or is there any estimation software or formula out there?

May a good samaritan having accessibility to the Japanese volume below please upload for the benefit of the interested forum users.
JIS / Japan Society of Civil Engineers (2005) “Recommendation of environmental performance verification for concrete structures ,” JSCE Guidelines for Concrete No.7.
Its a part or whole of a series of JIS/JSCE, (English)
This classic text, still widely used, covers pressure variation in accelerated flow, the effects of gravity and viscosity on fluid motion, theories of surface resistance and form resistance, lift and propulsion, surface tension, role of compressibility in fluid motion and more. 224 illustrations.

I have de Etabs 9.5 version. I am designing a 40-story building with steel, the proplem that I am facing is that when asigning the steel deck between the secondary beams and run the analysis. I do not get any warning, yet after steel frame design, It only appears the information on some beams and all columns, but there are several beams without information.
The thing is that by changing the deck section to a comon slab section and reruning the analisys and design, the information of every beams and columns appeared.
So I wanted to know what is the problem here, because I need to use steel deck in my building
