                Beam columns directly: conf. presentation

                Shear (proposed ballot from Australia)

                Wrap-up (Lecture)

 

Supplementary Materials

Analysis

   CUFSM download the latest version + more tutorials + source code

   CUTWP reads CUFSM files and gives you classic global buckling solutions

   Finite strip method research page lots of neat work, soon any boundary condition will be handled

   The constrained finite strip method (cFSM) automatically classify and identify local, distortional, and global

Cold-formed steel

   Direct Strength Method summary page of all things Direct Strength

   Direct Strength Method for members with holes summary of research, recent ballots  

   Sheathing Braced Design of Wall Studs summary or research, including lots on bracing CFS

   Inelastic bending of CFS members 2nd ballot summer 2009, take advantage of M > My, easily!

   Modeling cold-formed steel general guidance on modeling cold-formed steel for researchers

  Completed Projects

   Local buckling of C's and Z's in bending project showing test results of local buckling of beams

   Distortional buckling of C's and Z's in bending distortional buckling of beams

   Distortional buckling of columns distortional buckling of columns, lots of early DSM development

   Rotational restraint of sheathing test results providing bracing strength of different sheathing types
