I have problem with "Ultsup" command

Question

I cant check with "UltSup/Rein" 
 Error messeger " Error: UltChk-Rei: ELEMENT 1001/ 2 -Mz .........." 
 Can you help me?

I copy once more my comments given in your raised Service Ticket I answered already yesterday (also for others to see): 
 Note that one of the possible hints within the error message is saying that the "number of iteration within QS-Int might be too low". 
 If you look at the forces for the elements reported (cross-members at bearing axis) there are very small forces, i.e. moments and normal forces which sometimes can cause that the default number of iterations isn't sufficient for finding equilibrium within the iteration procedure. 
 Therfore go to Recalc Pad / CS-Integration and and set " Iterations " to 10000 which should solve the issue. 
 In pre-stressed structures note that you also should define the initial strain load case within the actions UltSup Rein and UltSup UltMz.

Respective settings of user-defined minimum and maximum reinforcement will of course have an influence on the Ult-Check. If e.g. more reinforcement is required than it is allowed to be added due to user-limitations (Amax), no equilibrium can be found. 
 Note the meaning of Amax and Amin: 
 Amax = Maximum allowed reinforcement area per length unit of the defined reinforcement layer (reference line), e.g. [m2/m]. 
 Amin = Absolut value of the minimum reinforcement in a certain layer (added only if reinforcement would be required at all). 
 Note that minimum reinforcement due to design code or design-engineering requirements shall always be specified element-wise as predefined reinforcement (in  Structure  Elements  Checks): 
 Edit a particular ref-set in the bottom table and define Al (A1 Input). Note to leave the flag set to "variable" if the program should add more reinforcement if required (setting the flag to "fix" would keep the user-defined value even if more reinf. was required and could again result in the problem that no equilibrium can be found).

Shear check in RM Bridge is carried through using "strut and tie model". 
 The error message "shear failure" is given, when the strut (concrete) fails, i.e. there cannot be found an equilibrium anymore by adding reinforcement. Therefore the user has to increase the cross-section resistance respectively (e.g. width or height of webs).
