Why the large body was not taken into account in the transient analysis.
Dear community members,
I wanted to carry a transient structural analysis for a historic mosque using a 10-second scaled accelerogram. I transferred the model from Solidworks. I used SOLID187 as a finite element. For the same model, I also performed nonlinear static and modal analysis under gravitational loads. Although there was no problem in these two analyzes, I was able to calculate the stress and deformation values for the minaret only in the transient analysis. I was able to calculate very very small stress, strain values on the main body as if the main body was hardly ever affected by the acceleration. I could not evaluate as to what caused this situation. I should mention that the minaret is integrated with the main body and rises from inside the main body. Besides, in the model, the minaret was modeled as a separate solid body and the contact surface between the main body and minaret was defined as bonded contact.
I would be grateful for your help in this matter.
