I am doing a steel project for the first time, friends, I need help urgently. The project seems to be saving, but what is the slenderness error in the scissors subtitle? How to fix it? and review the project in the link and write how it is in terms of cost, application and easy availability.
Re: I need to deliver urgent help!!!!!!!!!!!! Hello; Scissor subheading is not obligatory in regulations, it is a warning. For this reason, your employees are not shown in red and do not give a warning of inadequacy. To eliminate the problem, you can add a stability beam from the nodal point coming to the ridge area in the sub-headings. Details are available in the video at the link. At the same time, there are similar examples in Earthquake Code sample questions.
* Check the overlay loads in your project. Is that all your coating load? According to TS 498, is there no need for a snow load entry? If all your loads are this much, the cross-sections of the purlins may fall. *I changed the ductility level and R coefficients to normal and 5 from the analysis settings. If you examine the earthquake code, you can see that a solution with normal ductility level can be made for your structure. * You should create a sliding joint for your beams that are weakly connected to the columns. For example, you can use a single slip plate joint. * The way to drop the purlin sections in your model is to remove the purlins from the analysis and to use the cross system to ensure the stability of the truss overhead heads. I arranged your structure carrier system as a central braced system. For this, as I mentioned, you must enter a sliding combination. In order to understand the logic of the program and to produce the right solutions, you must watch the 5 videos in the link.
