Abstract: This study presents a knowledge on the shape modes behavior of steel IPE300 castellated section with square and hexagonal opening. These sections may be used as beams, columns or beam-columns member. The first four modes of failure will governing the use and application of these sections in the multistory building or bridges. Castellated technique become a promising technology for increasing flexural and shear strength of the same section without any additional material or weight this due to increase the depth of the section (by cutting the proper shape). A 3D numerical model was carried out by finite element program Abaqus to explore the performance of castellated IPE300 section under various types of loading. A parametric study also was prepared to focus on fundamental time period and mode shape. The obtained results indicated that a significant increasing in frequency by about a 28.3% due to increasing in the flexural bending stiffness of the castellated beams comparing with original reference beam.
