Flexural Behavior of Steel Girders with Web Openings
Authors
Abstract
Due to financial constraints and architectural reasons, height limits are not unusual in multi-story buildings. Large pipes and ducts must typically travel through significant voids beneath steel beams (SB), which results in non-economic floor heights. The use of steel beams with web openings (WO) to create the necessary area for services is the most frequently used treatment for this problem. The presence of apertures might potentially result in a notable reduction in the load-carrying capacity (p) of the beam, contingent upon the specific characteristics of the openings, such as their form, quantity, and placement. The current study intends to investigate the mechanical behavior of steel beams with web openings in flexural zones. An experimental (exp.) investigation was prepared and carried out. The objective of the study was to ascertain the structural response of steel beams with web openings in terms of their maximum load-carrying capacity and deflection (Delta). The behavior of such beams has only been investigated for vertical loads. A series of experiments were conducted to investigate the structural behavior of ISMB 100 hot rolled steel beams having web openings, ultimately leading to their failure. The beams were supported just at their ends and experienced a concentrated load applied at the midpoint. The experimental investigation examined both circular and rectangular apertures. The generic finite element analysis program, ANSYS, was utilized to analyze all of the beams, and the resulting data was afterward compared to the experimental findings. Furthermore, the experimental findings facilitated the development of a finite element model for beams with web apertures, resulting in a satisfactory correlation between the observed outcomes and the computational results. According to the results, circular openings in beams perform better than rectangular openings and the position of rectangular openings is a major factor.
