Pool Bar

In a system like this hotel pool bar in Muğla — where an existing circular concrete column acts as the primary support and stability is provided solely by tension-only steel members — non-linear analysis is required because system stiffness does not stay constant through loading. When the axial force in a tension member drops to zero the member can go slack and its contribution disappears, while another member may engage at the same moment. That makes the load–displacement relationship and the force distribution non-linear by nature. The ANSYS, CSI and MIDAS documentation all classify tension-only behaviour as this kind of status-changing non-linearity requiring an iterative solution.
