Analysis the basic cutting shear and the tension of column of steel frames subjected to wind load by using three design codes

Abstract

Globalization of the construction industry and the development of international codes and standards have
intensified the need of better understanding the underlying differences between standards of the wind loading.
this paper, discuses the linear analysis of steel frames 2,4,7,10,15 and 20 floors, explained by using three
design codes, ANSI 7-10, NBCC 05 and Iranian building code, part 6. In this paper we discuss the criteria
that includes: cutting the base and Master Civil Construction. .One result of this study indicates that the
proposed rules in the bylaws of America, Canada and Iran for the building that are analyses in a linear static
way, in some cases, do not provide adequate safety against wind. According to sixth topic the basic cutting is
less than the cutting according to NBCC regulations and the cutting according to NBCC regulation is less
than ANSI regulation. According to all 3 regulations, the basic cutting increases by increasing the height.
According to the 6th topic, in every frame compared to a shorter frame the maximum stress, increases by
increasing the height and reduces by increasing spans. According to the sixth topic the maximum shear stress
increases by increasing the frame height.
