Steel beam members can span up to 18m, but the most usual range of steel beam spans rang from 3m to 9m. Beams commonly transfer loads from floors and roof to the columns. Various prefabricated beam sections are available to be used in the construction multi storey steel frame structure. When circular steel columns are used, weld connection is used to join both steel columns above and below.įig.7: Column Splices Erection of Steel Beams The distance between floor and column splice is about 60cm. 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.įig.6: Steel Column to Foundation Details, (A) Top bolt places created in base plate, (B) Side view of column base to foundationĪs far as column splices are concern, it is provided in every two or three storey to ease erection process in addition to simplify steel column production and deliveries. Typical details of column to foundation connection is shown in Figure-6. The most desired shape of base plate is square and rectangular shape. Regarding foundation to column joints, base plates are welded to the end of columns. The most significant point in column installation is the connection between foundation and column and splices between columns. There are various sizes of steel column section to choose and these steel columns are commonly produced in advance. The section of the steel is specified based on the load imposed. The next step of steel frame construction is the placement of steel columns. The pile foundation would transfer the load of the structure to the stiff soil.įig.4: Pile foundation to transfer loads of steel frame structure though low soil bearing capacity of stiff soil with adequate bearing capacityįig.5: Steel Bearing Pile Driven into Ground Steel Column Construction If the strength of soil is poor and the imposed load is large, then it is recommended to consider pile foundation. These foundation types transfer loads to soil capable of supporting transferred loads.įig.3: Reinforced Concrete Bearing Pad Foundation for Steel Frame Structure Soil investigation including surface and subsurface exploration is used to assess the condition of soil on which steel frame structure rests.įor example, when moderate or low loads are imposed, then it is advised to use reinforced concrete bearing pads or strip foundation. Generally, the types of foundation required for the given structure is based on the soil bearing capacity. Steel framed structure construction begins with the construction of its foundation.
