I have created a Truss model and provided the supports as simply supported but still I am getting hogging moment at end cross girder. While I am getting sagging moment on inner girders. Kindly review. I have attached the model .75 m Truss.STD
The inclined members 16 17 45 46 are not declared as truss members, so they are transferring the bending moments to those girders. You can either declare those inclined members as truss or assign moment releases to those girders to avoid the hogging moments.
