RAM Elements error during design Access Violation

Diana Trombly — Mon, 18 Mar 2019 12:52:30 GMT

Hello,

I created a model in 3D and was having no issues with it, until I "save as" ed the file to a different name. Now when I try to "design all" members the program force-closes, and when I try to design walls in the concrete module, I get an error stating access violation and the model is no long analyzed. I am not sure how to resolve this issue and would appreciate any input. Please see attached file.

Thanks,communities.bentley.com/.../90-Percent-Design-18-MAR-2019.etz

Ram Elements Modelling Issues- Steel Truss and Concrete Walls

Diana Trombly — Wed, 27 Feb 2019 20:44:29 GMT

I am having issues modelling a building with a steel truss supported by concrete bearing/shear walls. The issue is that I cannot "assign" concrete wall design to walls unless they are only connected to four nodes.

If I segment each wall so that they are connected by only four nodes, then I have issues with the openings (windows and doors) spanning more than one shell and I get an error that the openings are too close within the concrete wall module.

What is the easiest way to model this geometry? My file is too large to attach.

Modelling a pinned column for LRFD in steel module- only able to use ASD check code

Diana Trombly — Wed, 18 Apr 2018 17:40:47 GMT

Hello, I am trying to model a simple pin-pin connected column for an axial force. The material is A7 so I have changed the yield strength to reflect that and I have added cover plates to model some reinforcement that was completed on the column. For some reason, when I go to the steel design module, I only have the option to check the column with the ASD code. I want to check with LRFD. Also, I am wondering if I have picked the correct support types for modelling a pinned column loaded in this manner.communities.bentley.com/.../VA-colum-307.std

Plate Connections

Diana Trombly — Mon, 22 Feb 2016 21:56:30 GMT

Hi All,

I am fairly new to STAAD, but I am creating a model where plates connect perpedicularly into the web of an I- beam. (imagine a beam to girder connection, but instead of a beam connecting to a girder, it is a plate).

In my model, the load is applied to the plate, and then needs to transfer into the beam. Can STAAD model this type of connection or is the program only capable of connecting elements from a table? There seems to be an issue where they are not properly connected. Thanks!

Oh and I am trying to model a welded/bolted double angle shear connection.

I am not sure why the connectivity is not correct.

Frame Analysis Using Prismatic Members

Diana Trombly — Fri, 23 Sep 2016 06:46:57 GMT

communities.bentley.com/.../22SEPFrame.stdI am performing a frame analysis and need to use circular steel prismatic members as beam sections. When I perform the analysis, the result I get is that the prismatic members are overstressed due to flexural stress. The stress in the beams does not correspond with my hand calculations Stress=M/S and in fact is way off. It appears that the moment in the beam is correct and all of the member properties are correct (i.e. moment of inertia, modulus of elasticity) so I'm not sure how the stress could be so high. There is no axial stress. This is only happening for the prismatic members and I have encountered this in the past.

Any ideas on how to fix this would be greatly appreciated.

Polygonal Plates Improperly Connected

Diana Trombly — Thu, 19 May 2016 20:47:47 GMT

I created my model with two holes through plates. I achieved this by polygonally meshing the plates and creating a hole simultaneously. Then I needed to mesh all other connecting plates. Now I am getting warnings that my plates are improperly connected and that some plates are warped or not shaped well . Is there any way to create a round hole and mesh the plates so that they are properly connected? I have attached two photos.

Fillet Welding Plates to Beam Webs

Diana Trombly — Tue, 29 Mar 2016 17:49:47 GMT

Hello,

I am trying to fillet weld plates to Wshape webs. I have attached my model for reference. Can this direct weld be done through STAAD? I am not able to assign connections or use RAM connections until I assign connections.
