Abstract: Openings in webs of steel beams or steel beam column are commonly used to reduce the material volume without affecting the structural strength or serviceability requirements. Most of previous research focused on the behavior of beam with web opening but only few concentrated on beam column with web opening. This paper highlights the behavior of steel beam column with different shapes of web opening at different locations. A finite element software ANSYS 19 was used for modeling beam column element with web opening. The results obtained from this study have shown that, load capacity of beam column with circular web opening is bigger than that of beam columns with square or rectangular web opening. The behavior of the steel beam columns became weaker and the vertical deflection at failure stage is increased when the area of web opening has been increased. Whenever web opening is located near to location of applied load that is lead to increase deflection. Keywords: Steel Beam-Column, Web Opening, Load Capacity, ANSYS.
I. INTRODUCTION Openings in webs of steel beam are commonly used to facilitate electrical, mechanical, and sanitary works in addition to access inspection equipments, ventilation ducts, air condition ducts, communication systems, fire protection systems. Another important reason for using web openings in steel beam is to reduce the material volume without affecting the structural strength or serviceability requirements. The steel columns were studied in much previous research by using experimental investigations and analytical solutions. Herein, some of these researches are presented. Shanmugam and Dhanalakshmi [1] have presented a numerical study using the finite element package ABAQUS to develop a design equation to determine the ultimate load capacity of perforated channel short columns containing single or multiple openings of square and circular shapes. The suggested equations use web plate slenderness and opening area ratio as the main variables. The accuracy of the suggested design equation is validated against number of experimental and finite element results available in published literature. Salhab and Wang [2] have suggested a method to calculate the equivalent web thickness of thin-walled channel sections with perforated webs to be used in the design of solid sections. The suggested method was based on a regression analysis of a numerous of finite element simulation results of elastic local buckling resistance of perforated plates under axial compressive load. It has been shown that the equivalent thickness is significantly related to the plate width to thickness ratio, the total width of perforation
