The steel cross sections available in the Libyan shops and their using

Abstract

In this research the demonstration of the importance of using small steel cross sections accomplished which fabricated in Libya; in Musrata steel factory where available in the Libyan markets. connection of sections by technical possibilities to obtain suitable dimensions ; length,  width, thickness to employ in the engineering structures. The connection of many elements used for obtaining sufficient ability to beer buckling, deflection and torsion. A study has been conducted on one of the steel profiles that available in the Libyan markets to illustrate the importance and opportunity of employment in the multiple story steel buildings. A large range of employing small cross sections by connecting them together to obtain cross sections has ability to gain the applied loads and satisfy engineering demands. Using of steel structure has large range in the constructions in the cold and hot countries. The focus is to obtain suitable procedure for the operation of thermal protection. Two deferent methods amplified in the designing to illustrate opportunity of obtaining amount of story from each method.  A study conducted on the profile channel 140 * 60 * 16 Kg/m to determine the ability of bearing the loads and determine the amount of story may conduct by this profile. It is possible to combine two or more of the cross section to build multiple story building not increases than four stories according to selected dimensions, and that depends on the selected perfect manner of suitable combination of the column and the spaces between its components. Two methods conducted to combined the columns; the first method employs bars with area of cross section 40 mm, 15 mm, and 559 mm length, and angle with 40 degree inclined with vertical axis. However the second method depends on the support of the column with plates, its width 265 mm, thickness 12 mm, and its length 400 mm.
