RAM Elements Repetitive Base Plate Assignment

Alex Alvarado — Fri, 29 Apr 2016 20:06:44 GMT

I have 1200ft of pipe racks, with the same anchor and base plate design. Can a template be created to apply a single bp design to 122 nodes?

RAM Elements Base Plate and Anchor Design

Alex Alvarado — Mon, 02 May 2016 17:14:09 GMT

I have developed a pipe rack model with several basic load cases. I have developed different load combinations for both, ASD and LRFD. Under load conditions, I have assigned "Design-Steel" and "Service" for ASD combinations and "Design" for LRFD combinations. When checking for base plate and anchors, I notice none of the LRFD load combinations are accounted for. Please advise; provide documentation if possible. I also have the following questions:

1- Do I need all three types (Design-Steel, Service, Design) to design steel with ASD and anchors?

2 - What is the difference between "Design-Steel and Service"? Do I need both for ASD steel design only?

3- How is the Design (Hot-rolled ASD or LRFD) and load conditions type (3 mentioned) interact? Do they need to match (Hot-rolled ASD with Design-steel & Service or Hot-rolled LRFD with Design)?

I have exhausted resources (e.g.: manual, web) trying to understand the differences between them.

Thanks!

RAM Elements - Assigning Gusset Connection to Chevron Bracing

Alex Alvarado — Mon, 10 Aug 2015 17:40:13 GMT

On a pipe bridge, a gusset CVR connection is to be applied to a Beam-Brace connection. No issues were found with lower gusset to beam connection with lower right and lower braces coming in. Errors were encountered where this same connection was applied to two lower braces (left and right) and an upper right brace: "No valid joints where found within selected members". Any recommendations?

RAM Elements - Assigning gusset base plate connection to box truss bridge

The gusset base plate has WT chevron bracing coming from both longitudinal and transverse directions on to a W column (1 to flange and 1 to web). When assigning a gusset bp connection in RAM Elements, the model would not allow for a two-brace, gusset bp connection. Any thoughts?
