Hello, I need to project a steel fire escape. There is no problem in defining elements such as columns and beams, but I have no idea how to define the steps. good work everyone...
 
Hello there; You can find a sample project attached. What you need to do is to create the step section on the plan using commands such as line, continuous line, and select these two-dimensional lines, which are closed polygons, and convert them to a plate using the transform-polygon command in the right-click menu and complete the modeling. Good work.
 
Hello, thank you for the examples, but I did not succeed, you draw these plates one by one in the plan and then give them jeans or give them a ladder shape, it will be more understandable if you show them with a small video narration, good work
 
I made a model for the first arm, you can continue the second arm similar, this is just an alternative, many different solutions can be considered.
 
Dear guraykose, thank you for your attention, I would like to ask the following: As far as I understand the location of the L elements, you are determined by define local point. In the solution, should we show the L elements as welded, also why do we not give thickness to the plates, to not take them into account in the calculation?
 
Yes, with defining catch points on the element, L corners can be the most practical support form welded, alternatively you can weld the support corner and connect the step corners with bolts, you are right, the thickness of the selvedge cannot be entered for some reason, you can choose a thickness between 2-3 mm from the diamond sliced sheet in the application. Good luck with. G.Kose
 
Hi, I'm still having problems, syn. With guraykose's help, I placed the stair treads, drew the L elements up to the outside of the stair arm, then fully fitted inside with a welded joint, then added metal trim and sheet metal inside, but the metal trim was defined between the initial lengths of the L elements before welding. I'm also getting an error on a stringer of the stair arm. analysis will be seen. I ask for your help.
 
Dear colleague, the sheet metal coating is only for you to load, it is not important to position it in the raw length, you can correct it in the drawing, the main thing is that the model can be properly analyzed and the design can be made.
 
Of course, you are right, I am trying to learn the event in this simple system and not to deal with later corrections on the drawing in more complex and hasty projects. Thank you for your interest...
