It is possible to assign negative mass to a joint as long as the total mass tributary to the joint remains positive (or zero). If negative mass is assigned to a joint, do it with great care. If SAP2000 detects negative mass at a joint during the analysis, SAP2000 will set the joint to zero with a warning.

Then go to Assign>Joints>Restraints and assign the joints as fixed shown in the image below: After you assign the restrains try to do the run-analysis again. If in case you encountered an instability message for the second time, then try the next option.

A negative buckling factor simply means that the structure will buckle when the directions of the applied loads are all reversed. A classic case is a pressure vessel. allianz kristina radloffWebb29 mars 2024 · If I were you, I would delete all these red walls and provide columns here just to check if the rest of the model is working fine and the walls are the only elements that causing problems. This way I can focus all my energy in finding out why walls are behaving in this odd fashion.
