I working on the curtain wall system. Usually, I model cable structure for support glass wall by using FEM from Strand.7 program. Normally about cable structures need to assign Pre-load/Pre-Strain.nmy question is.nWhich is the best way to create a cable structure model?nHow to assign Pre-load/Pre-Strain to members?nIs the Ansys program suitable for my work?nbest regardnPInn

nANSYS can model cables and assign an Initial Strain. Search for INISTATE command.nThere are many discussions on cables on this forum.nhttps://www.google.com/search?q=site%3Aforum.ansys.com+cable+model+inistaten

ArraynI have aquestion about the properties of cable nsection of cable in the program I was use circular cross-section.nIt's can adjust only dimension but i want to adjust dimension and area nbecause i want make same properties with my cable specnthis is my cable specnDo you have any suggestions for me ?nBest regardnPInn

nMeasure the bending stiffness of the cable. That stiffness provides a value of EI.nCalculate area moment of inertia for bending, I from the radius r of the actual diameter of the cable.nCalculate what E must be so that the product E*I equals the EI measured from bending the cable.n
