STRUCTURAL EFFECTIVE PROPERTIES of ELASTIC CASTELLATED SECTIONS

Abstract

Castellated beams are usually manufactured from IPE wide flange rolled sections using castellation process, to obtain additional capacity in bending. Studying and determining structural equivalent stiffnesses of them is needed for all designers to investigate their behavior closely. In this paper, major and minor flexural stiffness are calculated for a wide range of CPE shapes. For obtaining flexural stiffness, models were analyzed under the effect of bending moments. Based on the results of this paper, the castellation process causes a reduction of only 4% in major bending capacity, which in turn shows satisfactory behavior of the beams subjected to no-buckling bending.
