Cutting problem on the struts on the pedestrian bridge

Hello, in the attached file, I tried to draw a pedestrian bridge, whose manufacture was finished, for learning purposes... but there are problems with the struts. Can you help me fix the problem here.
 
Hello there; 1- It will be most appropriate to enter struts and diagonals with a single steel cross command. 2- Do not enter the struts and diagonals with the steel column command. If you enter with the steel beam command, select the elements and activate M22 and M33 from the right button - properties - freedoms section. If you enter one diagonal, this will not be necessary. 3- When modeling the welded joint, after selecting the joint so that the nodal points are formed at the intersection of the perpendicular and diagonal, first select your main beam, which acts as the truss subheading, then right-click. Then select the sewing and diagonal and complete the joint modeling with the right button again. Good work.
 
Hello again, I arranged the cross between the trusses and the diagonals. but whatever I did on the lower beam I couldn't fix the deflection error. I also drew I100 intermediate beams as secondary beams, it gives a deflection error. When you draw them as beams, the problem disappears, but when you connect them with welding or bolts, it gives a deflection error again. I ask for your help in these matters. I think I'm making an analysis error somewhere.
 
Hello there; We are getting analysis error under g upload in the project you sent. That's why the results of your elements aren't rendered anyway. While creating the trusses, you have realized the perpendicular and diagonal as we have stated, but the PMM ratios are quite high since you have designed the lower and upper fish to receive moment. If you are going to use only axial force, arrange accordingly. Or, if you want to design in a way that transfers moment, it is seen that you need to make arrangements in the sections. Column and beam sections have been arranged in your project. However, in the elements you are trying to create with the main secondary beam, there are joint point errors in your beams modeled with IPE 100, therefore the analysis of the model cannot be performed. Rebuild these beams by defining the working plane. Because they do not pass through the axis of the beams to which they are attached. Good work.
