can you help me ?

For intradosed i want Sofistik calculate the initial losses ( friction loss at strut and at diaphragm over the pier and slip losses and elastic shortening .

I use this option

(PEXT nog 40 P0 11000 side posx beta 0 mue 0.2 ss 0) but the normal force for external cables not logic as the force difference is very small before and after strut and before and after piers

can you help me to solve this problem ?

Any help ?

May be you try SLIP cable in ASE. This ensures the same forces in all (selected) cables.

For details see manual for ASE.

i want to consider the friction losses at struts and over piers so i used ( PEXT ) to consider friction losses and slip losses of external cables so the force of cables must be different before and after the strurs and pier location ( this is continuous cable ) but after anaysis the force difference is very small and this is not logic

so i need to know it is necessary to modeling the cables with curvature before using ( PEXT ) or my modell as above correct to consider friction and slip losses
