Regretfully for the Gen section the properties are used by the analysis only. The Gen shape is a tool used by many to create a dummy member as you could assign low values so it is not interfering with the rest of the analysis. Other section under…

Here are the details from the program manual. At 2 1/4:12 I think it would be wise to involve a joist manufacturer. Chord compression would be the main concern.

If you want a clean, mitered connection there, then you can miter or skew the ends of each beam (e.g. at 45 deg), but overlapping does not really cause any problem. If the beams are the same depth then you can also just stretch them to overlap. If one…

Here is one I happen to have. It goes in the tables folder, C:\ProgramData\Bentley\Engineering\RAM Structural System\Tables https://communities.bentley.com/cfs-file/__key/communityserver-discussions-components-files/5932/DBLANGLE.CON

You would have to get those from the manufacturer. Just using the values of some solid sawn lumber is a start.

Good enough in my opinion. The whole concept of semi-rigid diaphragm analysis, including the effects of eccentricity is far beyond what anyone would have considered 20 years ago. Most of the buildings in New York and Chicago that have been standing for…

We fixed one issue but broke another in this version. We will implement a fix for the next update.

You could eliminate the cantilevers altogether and simply use a large slab edge overhang. You'll get designs that way, though they could be unconservative.

Model short beams (of any material) between the tips of the cantilevers. Then model the slab edge out-board of those perimeter beams, Be aware that cantilevers on joists will also cause a special (SP) design case. See this for more: communities.bentley…
