Purpose To date, there are no studies in the literature that provide a comprehensive understanding of interrelationships between slenderness ratio and main design criteria supertall towers (=300 m). In this paper, important issue was explored using detailed data collected from 75 cases. Design/methodology/approach This paper carried out with review including database Council on Tall Buildings U...

Steel beam cross sections are normally classified according to the effect of local buckling on the moment capacity of the section. This is achieved by defining slenderness limits for the flange and the web. This paper describes a series of bending tests on cold-formed RHS to examine these limits. The resulting experimental relationship between web slenderness and plastic rotation capacity is gi...

Different expressions have been developed to determine damping of structures based on various hysteretic models and ductility levels. Since Slenderness ratio is an important parameter on the hysteretic behavior of special concentrically- braced frames (SCBF), in this paper new expressions for determination of damping of such frames are developed based on slenderness ratio and ductility. Two typ...

a subject of the investigation is the behavior of concrete and reinforced concrete columns under different loading conditions. the experimental study comprised a great number of tests on hinged - end columns with slenderness ratio within 35 and 155 subjected to both short and long - time loads applied at different eccentricities. the strength of concrete and the steel percentage varied in a wid...

Geometric imperfections such as radial imperfection, diamond shape, and local dimples could affect the buckling mode and load carrying capacity of axially compressed steel tubular columns. This paper experimentally investigates the effect of radial imperfection on the load carrying capacity of tubular columns. Test samples include 100 specimens with different values for diameter, length, thickn...
