| In recent years, Light steel structure is applied more and more widely in theengineering, especially the monolayer steel structure, which takes the shape of theportal frame structure is more common, because of its light weight, simple structure,excellent mechanical properties, there are a large number of applications in themonolayer steel structure, instead of the structure concrete frame of this constructiontechnology complex. In various embodiments, the safety of the structure are focusedon the structure of the portal frame, due to the development of constructiontechnology limited life, all aspects are not mature enough, it exists security hiddendanger, This paper focuses on the aspects of monolayer steel structure of accidentprevention content.The main research contents include:1. A detailed overview of the design method of portal frame light steel structureand summary, Avoid design personnel and bring misjudgement due to unclearunderstanding of relevant provisions in the design, avoid engineering accident loadselection, node design, the errors caused by.2. Construction method for structural steel single portal frame were introducedin detail, have been part of process of lower part and an upper part of light steelstructure, at the same time, should pay attention to the construction of the two partsof the handover of the problem are introduced. Pay attention to basic constructionproblem is the foundation, anchor bolt construction aspect question; should payattention to the problem of light steel structure parts include the production of steelcomponents, installation and transportation.3. Through the ANSYS for single frame door frame and multi span portal frameby finite element analysis, to determine the force the door type steel frame understandard loads and the roof purlins; portal frame in occasional steel frame and theroof purlins load. The steel frame and the purlins in two kinds of two kinds ofloading the stress characteristics were compared with the stress condition. |
