Can you use a ground floor slab to take horizontal forces from columns? Instead of relying on spread footers to resist sliding.
Typically I have not because the slab is placed with expansion joints around the columns but I was curious what others do
How do you obtain story drifts from STAAD with a dynamic analysis? Should you use the node displacements? Or the PRINT STORY DRIFT command? And do you need to factor up displacements Cd/I (see ASCE 7-05 12.9.2)
Thanks
I am working on a Mathcad file for calculating torsional stresses. Looking at AISC Design Guide 9, is there a way to calculate the values in the graphs in Appendix B instead of looking at the graph to come up with the values?
Thank you
Does anyone who has taken the SE I and II exams know if you can bring the Sructural Engineering Reference Manual to the exams? (ISBN: 978-159126-119-3)
It is an open book exam but I understand there are some limitations as well. Any help with this is appreciated.
Pipe bent consists of two columns with three beams (moment connections) between columns. Out of plane it is free (no bracing or tie backs). What is the K factor out of plane? Should I use K=2 like a cantilever or can it be reduced? Thanks for the help
Paraphrase of IBC 2003 Section 1620.2.9:
Columns subject to vertical reactions from discontinuous walls or frames...shall resist special seismic combinations of 1605.4.
My question is:
Can someone show me a graphical representation (or a link to this subject) of which columns are subject to...
