Monoslope Roof

Hi guys. I am a new user in staad. I tried modeling my file but i can't run it as a whole. Can someone give me tips on how to model this on my staad? 

at the same time, i am trying to analyze it part by part, but can't seem quite to run it due to instability errors. Please help me on how to run this structure as a whole. This is my trial partial staad file. 

Thank you in advance for those who will help me. God Bless.

  • Dear user,

    There are a lot of training videos in our learn server. You can access those items from below link.

    https://learn.bentley.com/app/Public/ViewLearningPathDetails?lpId=112344

    Regarding your model, there are some modelling error. The connectivity between the members are not proper. You can check it from Utilites > Structure Tools > Multiple Structure.

    You can break the beams at selected nodes or intersect the beams as appropriate from geometry tab as shown below.

    I would suggest you to view the learn videos from the attached path first and then try to make a model.

    Thanks & Regards,

  • Good day. I have already created a structure that has all the beams needed just like on the perspective. But i am really having a hard time analyzing how i can transfer my loads to rafters > purlins > I-beams > Columns > Footing. That is why i created the one i posted because i wanted to transfer the loads part by part. I was just asking how can i use staad on my structure as a whole. I would appreciate if you can tell me how can i do it and it would be a great reference for my future works. This is the file that has all the structural beams. Thank you in advance and God Bless.

  • A modified file is attached for your reference

    8623.Structure1.STD

    List of issues addressed in the modified model
    orphan node 114 deleted
    lot of duplicate members merged ( Utilities > Beam Tools > Duplicate Beams > Merge)
    analysis command added after load combination
    member properties missing in your original model- some arbitrary property has been assigned, you can make changes as needed
    material definition and assignment were out of place and moved
    design commands were out of place and moved 
    portal frame (formed by the members 3 38 35 in your original model) was not connected to the rest of the structure. Top level beam moved up and members intersected to establish connectivity 

    I would also highly recommend that you go through the learn server videos or go through a STAAD.Pro training which should clear all doubts that you are having now.
