Hello there; Attached is a steel bridge project. 1) Considering the temperature difference effects of the bridge, I want to load the temperature difference. I entered T1 and T2 values. After the analysis, T1 and T2 loadings do not appear in steel design combinations. Since the reduction factors are for beam, column, curtain, slabs in the analysis settings in the heat loads tab, does the program apply the heat difference loading only to the reinforced concrete elements? Or is there something I missed? How can I resolve this situation? 2) I cannot get a calculation report for the cross-end connections that I use in truss beam connections (because the program cannot design with the truss joint). In addition, I get an error as in the picture, in the diagonal additional junctions of the crosses that I connected the top header of the scissors (although not in the subheading crosses). What is the reason? 3) Geothermal power plant pipes will be transported on this bridge. I have defined the relevant pipe loads. Is there any problem in defining these loads? Is it necessary to make a new load combination for the respective loads? Finally, if you have any advice about project data entry and design, I would appreciate it if you would let me know. Good work.
