    Steel structure construction


    Structural steel consists of the steel work for buildings, structures and pipe supports. Structural steel also consists of steel work for the farming of bridge connections between structures and equipment inside and outside the building. Construction of steel framed structures includes construction of its foundations, columns , beams and floors systems. Construction phases of structural steel frame are discussed.

    Steel frame


    Steel frame structure foundation construction


    The construction of the steel frame structure begins with the construction of its foundation. Generally, the type of foundation required for a given structure is based on the bearing capacity of the soil.


    Soil surveys including ground and underground exploration are used to assess the condition of the soil where the steel frame structure is located.


    For example, when applying medium or low loads, it is recommended to use reinforced concrete bearing pads or strip foundations. These foundation types transfer loads to the soil that can support the transferred loads.

    If the soil strength is poor and the applied load is large, it is recommended to consider a pile foundation. The pile foundation transfers the load of the structure to the hard soil.


    Steel Column Construction


    The next step of steel frame construction is the placement of steel columns. The section of the steel is specified based on the load imposed.


    There are various sizes of steel column section to choose and these steel columns are commonly produced in advance.


    The most significant point in column installation is the connection between foundation and column and splices between columns.


    Regarding foundation to column joints, base plates are welded to the end of columns. The most desired shape of base plate is square and rectangular shape. Typical details of column to foundation connection are shown in Figure-6.


    It should be known that, the most desired shape of base plate is rectangular and square shape because such plates provide largest spacing between the bolts which is desirable.


    Erection of steel beams


    Various precast beam sections can be used for building multi-story steel frame structures. Beams usually transfer loads from the floor and roof to the columns.


    The maximum span of steel beam members is 18m, but the most common steel beam span ranges from 3m to 9m.


    When erecting steel beams, you will encounter column-to-beam connections and beam-to-beam connections. The type of column-to-beam connection is different, which is selected according to the type of load applied to the column-to-beam connection.
