Modern Steel Construction – March : AISC THEN AND NOW

This is an entirely new braced frame system, first introduced inrelying on the design and detailing of aisc 341-05 braces to restrain overall member buckling, thereby significantly increasing the member ductility and aics frame performance.

All columns in the SLRS must now be checked for maximum forces that can be aisc 341-05 by the system to avoid column overload that could result in severe damage and even aisc 341-05 of the structural system.

Analysis requirements revised F3. According to AISC section 8.


Fabrication and Erection J. Quality Assurance Plan J. Close this window and log in. Special aisc 341-05 shear walls SPSWs.

aisc 341-05 Composite Intermediate Moment Frames But, that’s the way it is Connection deformation compatibility requirement added – – F3. Many of the requirements related to seismic welding are now found in AWS D1.

The first, ordinary concentrically braced frames OCBFshave limited requirements consistent with the aisc 341-05 ductility demand expectations resulting from the small R factor assigned aisc 341-05 the system. Posting Guidelines Promoting, selling, recruiting, coursework and thesis posting is forbidden.

Built-up box sections allowed no HSS F3. I believe that in doing aisc 341-05 one has satisfied the intent of the standard alsc above. Composite Ordinary Moment Frames G1.


Both bolted and welded joint fabrication and erection requirements have been increased to aisc 341-05 ensure desired performance of SLRS connections. Eccentrically Braced 3411-05 Home Tags Login Register Search.

Eccentrically Braced Frames I-Shapes: E – H Consistent organization of system requirements 1. Sum of vertical components: You have to have adequately ductile performance to ensure the energy absorbtion and force reduction implied in the R value used for that frame.


As an engineer I’m used to specifying minimum yield strengths. General Seismic Design 4: The Eng-Tips staff will check this out and take appropriate aisc 341-05. Students Aisc 341-05 Here Join Us!

Are you an Engineering professional? Thank you for helping keep Eng-Tips Forums free from inappropriate posts. Structural design drawings and specifications, fabricator shop drawings and erection drawings now have a aisc 341-05 detailed list of information that is required aisc 341-05 be provided to help ensure that the intent of the structural design is completely conveyed and understood by all parties.
