The beginning

 

This fresh video is for designers who struggle with Staad Pro warnings. Let me know what you think about the video in comment box.

Followings are the warnings that has been covered in video
Type 1) ** WARNING - PROPERTY FOR MEMBER 13 DUPLICATED. LAST VALUE USED.
Type 2) **WARNING- MEMBERS 29 & 20 ARE BETWEEN THE SAME JOINTS.
Type 3) **WARNING- THE AXIAL COMPRESSIVE STRESS EXCEEDS THE EULER STRESS FOR MEMBER 5
Type 4) **WARNING** SOME MEMBER SIZES HAVE CHANGED SINCE LAST ANALYSIS.

 

Solutions (Watch Video or read following)

 

Type 1) ** WARNING - PROPERTY FOR MEMBER 13 DUPLICATED. LAST VALUE USED.

In Staad pro, we assign property of beam to beam member. Property means physical property like size, density, material, shape etc of the member. Sometimes two different property get assigned to single beam and this warning appears. Best way to resolve this is to reassign material property using toggle option in General -> Properties -> "Properties -Whole structure" tab or you can simply go to editor file and delete member form repeating property.

 

Type 2) **WARNING- MEMBERS 29 & 20 ARE BETWEEN THE SAME JOINTS.

In Staad Pro, to create a beam you need two nodes. By connecting node using add beam, you can create beam member. Note that you can create only one beam between two nodes. If by mistake you create two members between two nodes, this warning will appear. To resolve this warning just delete the other non-required beam or merge the beams from Tools menu. Go to Tools in menu bar -> Check Duplicate -> Members. If there are duplicate members in your model it will highlight with beam numbers, just click to merge to merge all duplicate beams to one.(Nodes and joints are same thing.)

 

Type 3) **WARNING- THE AXIAL COMPRESSIVE STRESS EXCEEDS THE EULER STRESS FOR MEMBER 5

When a very huge load compared to the load carrying capacity of the member is applied on the member, this warning appears. Best way to resolve this warning is to recheck all the loads and then if required increase the size of the member.

 

Type 4) **WARNING** SOME MEMBER SIZES HAVE CHANGED SINCE LAST ANALYSIS.
