Constructional System of Cold Formed Light Steel Framing (LSF)

1.825 962


Abstract. Nowadays, various methods are used to strengthen structures against earthquake. One of the new methods which can be used in improving seismic behavior of structures is to use light steel framing. Lightweight steel framing system (LSF) is a structural system which is employed to implement buildings which are mostly low and medium rise buildings (at most 5 stories). This system which is very similar to wooden structures’ construction methods is constructed based on applying some constituents called Stud or Track. The main structure of the building is established from combining cold formed galvanized profiles. The purpose of the present study is to define, explain and apply lightweight steel framing as well as referring to required machineries and physical properties of the needed steel. In this regard, the requirements of design, execution, shell life, various stages of designing, foundation of building, internal and external coverings of ceiling and wall, electric installations, doors and windows are also discussed. Finally, advantages and disadvantages of lightweight steel framing systems are stated. The present project can be introduced as the most comprehensive and complete instruction for lightweight steel framing structural systems.
