I am using spaced wood sections defined by your Leo SPCa.leo. There is one section in the standard United States group and we added several sections to a custom group for our office.
Our sections typically use 4 combined members. The members are typically 2x12's. So, we would have (2)2x12's nailed together with a space of 5.5" and another set of (2)2x12's on the other side. The total width of the beam-column is 11.5". These sections have bending in the major axis and axial stress. I have attached an Output Report for a beam-column that has a total of (2)4x12's and (2)2/12's as one example.
The program has a check box to apply the Repetitive Member Factor Cr in the Wood Design Parameters. The output shows that the member is a repetitive member under the heading "DESIGN CRITERIA", but the section "DESIGN FOR FLEXURE" for M33 shows Cr = 1.00 instead of 1.15. I checked the box to use 1.15. Why is Ram Elements ignoring this factor?
On another note for the same type spaced sections using SPCa.leo, the program will let me set Lu, but the spreadsheet tools will not assign Le. The error message says it only works for rectangular or circular sections. Why?
