“…Results are given for single circular openings with various diameters, single circular opening in the lower part of a web, single circular opening with vertical stiffeners and two circular openings horizontally or vertically spaced. Similar results for elongated circular openings, square and rectangular openings are presented in Hagen [15].…”

“…In addition to buckling, this reduction factor, or function, should also account for the effect of the reduced shear area of the web and of all secondary and tertiary effects of the presence of the opening. Hence, according to Hagen [15] the shear capacity of girders with openings may be given by…”

“…Basher et al [13] investigated the effects of circular or square web openings on the ultimate strength of horizontally curved composite plate girders. Some numerical simulations in order to provide data for the development of a design model for the shear capacity of steel girders with web openings, with and without transverse stiffeners and opening reinforcements were performed by Hagen et al [14] and Hagen and Larsen [15]. Lagaros et al [16] studied an optimum design of 3D steel structures having per-forated I-section beams.…”

According to the purpose of the opening and the structural designer, the shape of the web opening is decided. It is too easy to choose the shape of openings from regular shape whether it is circular or rectangular shape. The presence of openings in the web of steel beams decreases stiffness of the beam and introducing a larger deflection than in the steel web opening with solid opening. A steel beam with web opening is analyzed in this paper. ABAQUS software is using for analyzing nonlinear static and dynamic opening of steel beam with different position and supporting conditions.

Height limitations are not uncommon in multi-storey buildings due to economic requirements and esthetical considerations. Substantial spaces are normally required to enable the passage of large pipes and ducts beneath steel beams leading to uneconomic floor heights. The most adopted solution for this issue is the use of steel beam web openings to provide the required space for services. These openings could lead to a significant decrease of the beam load carrying capacity depending on the adopted openings shape, size and location. These aspects motivated the present study based on FE simulations calibrated against numerical and test results. The results accuracy enabled a comprehensive parametric analysis of beams with web openings to be made focused on the profile size, web opening location, among others. The study also investigated the efficiency of longitudinal stiffeners welded at the opening region and benefits of using an adequate edge concordance radius in beams with rectangular and square openings. The obtained results showed the need of using welded longitudinal stiffeners in order to increase the beams ultimate load carrying capacity. This adoption can double or even triple the ultimate load of beams with rectangular and square opening heights equal to 0.75 H, respectively.
