Dear Gents ,
I have model for concrete slab 4m x4 m with moving load by using dummy member colud you inform me which values of moment is the correct and i should adopted in design calculation for slab reinforcement :-
1- As per plate center stress is Max My i108.103 kn/m.m
2- As per plate corrners stress is Max 302
3- As per dummy member 150 kn-m
