Hi, We are doing our final year project in the design of PEB structures. so we are using staad software to design and analysis the structure. we have received more warnings and notes like "instability at joints, weak spring added for stability, zero stiffness added for stability, etc". we trstaad final 1.stdied to solve as our extreme. kindly help us to solve the warning and notes. Thanks in advance.
There are issues in your modeling. I can see multiple structure and orphan nodes in your file. You can check the same from Utilities> Structure tools > multiple Structure.
Also the connectivity between members are not correct.
Try to rectify the model so that proper connection between elements are established. You may refer the attached links to know more about instability problems.communities.bentley.com/.../zero-stiffness-warningcommunities.bentley.com/.../warning---instability-at-joint-2-direction-mxcommunities.bentley.com/.../staad-pro-instability-and-zero-stiffness-faq
Thank you soo much bro for spending your valuable time. Now I cleared multiple structure and orphan node error and trying to resolve stiffness, instability warnings. Shall I remove all warning and notes? if possible shall I get procedure to remove that.
