Theauthorsresearchpaperpresented,thevariouspublicationsontheanalysisofsteelstructureshavebeenbriefly discussed. After reviewing this previously published article, it can be concluded that the structure consisting of different steel sections is more stable. These steel structures can be effectively used for modern and fast urban constructionworks.Variousmodernsteelpartitionshaveproventobethemosteconomicalandsafestcomparedto traditionalpartitions.
