Σύνοψη

As the time goes by steel construction becomes a more frequently use for large buildings or projects . A steel frame structure consist of a skeletal framework which carries all the loads which the structure is subjected to and its task is to transfer those loads safely to the foundations.
Steel has several advantages instead of concrete. These are:
-A steel structure can be finished earlier than a concrete one.
-A steel structure costs less than the concrete one
-A steel member can be loaded more than a concrete one of about the same section e.g a skyscraber can not be made of concrete because of the big loadsand the concrete can not resist and withstand it.

One disadvantage of steel is that steel has less fire resistance than concrete.
The general idea of a steel structure is that all the loads are transferred from the floors to the floor beams and from there to the girders. From the girders the loads are transferred to the columns.
Loads are pass down from all the floor of the structures via the columns and finally are transmitted to the foundations and the soil.

STRUCTURAL ELEMENTS:
Steel buildings are composed of distinct elements:
-Beams and girders (carrying lateral loads in bending and shear)
-Ties (carrying axial loads in tension)
-Struts, columns, stanchions (carrying axial loads in compression)
-Trusses (carrying lateral loads, composed of struts and ties)
-Purlins (carrying roof sheeting)
-Sheeting rails (supporting wall cladding)
-Bracing ( resist wind and building )
-Bases (tramsit the loads from the columns to the foundations)

For the designing of steel structures a steel design code was created ( code we use is BS5950).
I When we refer to the term design we mean the selection of the proper section size to have the needed moment and shear capacity. After the proper connections are needed to be selected.
