Thanks for the reply....... Actually there is multiple structures but it can't be intersect.
Yes, i think somewhere its disjointed but i didn't find it. While i running anaylsis.....374 warnings are coming. the errors are as follows: ***WARNING - INSTABILITY AT JOINT 80 DIRECTION = MZ ***WARNING - INSTABILITY AT JOINT 80 DIRECTION = MZ ***WARNING - INSTABILITY AT JOINT 79 DIRECTION = MY ***WARNING - INSTABILITY AT JOINT 79 DIRECTION = MX
A modified file is attached. Some of the small columns were not connected to the rest of your structure leading to these instabilities. Since you have used MEMBER TENSION in your model, you would need to replace the LOAD COMBINATIONs with REPEAT LOADs.
More details on this are available at
I also added a PERFORM ANALYSIS and CHECK CODE after the SELECT OPTIMZED to ensure that the model is reanalyzed based on the selected sizes and a code check is carried out based on the final forces.
