Dear all,
I am fairly new to the PMEMBER and PBRACE command to do a steel design.
I have been having a problem with checking a cantilever column. I have modeled the column as a single vertical member with a fixed support at the bottom and free end at the top. I have then used the PBRACE command as below. I specify the fixed support to be "FR" and the free end as "U". However, for some reason it doesnt work.
45. PARAMETER 1 46. CODE AUSTRALIAN 47. PBRACE TOP 0 FR 1 U PMEMB 1 48. PBRACE BOTTOM 0 FR 1 U PMEMB 1 49. TRACK 2 PMEMB 1 50. CHECK CODE PMEMB 1 EFFECTIVE RESTRAINT COULD NOT BE FORMED. DESIGN OF THE PMEMBER 1 IS SKIPPED. DESIGN OF THE PMEMBER 1 IS SKIPPED DUE TO INTERNAL ERROR. ************** END OF TABULATED RESULT OF DESIGN **************
Could someone enlightened me on specifying the the PBRACE for a cantilever PMEMBER?
I used to specify "KY" and "KZ" for checking the cantilever member, i.e. traditional method.
Thanks.
