First of all, have a good work and have a nice day. In the project I am working on, I will present 3 different models to the owner, one of which is the system consisting of a truss reinforced concrete column and a steel column, the owner will apply whichever of these three is economical. /onedrive.live.com/redir?resid=4B10C88935B9DC59!659&authkey=!AGsfDX-UywonJ3M&ithint=file%2crar]https://onedrive.live.com/redir?resid=4 ... file%2crar[/url] Do I need to increase the sections to overcome it or is there a point I missed that I can't see, thank you in advance for your interest... good work
