“…All web openings were located in the middle of the subpanels. Nevertheless, the position of the web opening seems to have hardly any influence on the shear resistance according to Wang et al [15].…”

Plate girders with I‐section frequently require large web openings to accommodate ducts and pipes in buildings and bridges. It is known that the critical load equivalent to an unperforated plate can be achieved by an appropriate reinforcement of the web opening. The majority of the investigations on thin‐walled webs with web opening under shear loading has been focused on web slendernesses ranging between 200 to 360. Three tests on plate girders with a web slenderness of 416 are presented that contain web openings. The effect of an all‐around reinforcement (hollow section) of the web opening is studied in three‐point bending tests. The tests are calculated with finite elements accounting for imperfections that had been measured before testing. A parametric study is performed to evaluate different types of reinforcements for high web slendernesses.

“…An alternative effective and economical solution is to apply appropriate reinforcements around the web opening regions such as to alleviate the detrimental effects of such large web openings. Numerous studies (Segner 1964;Congdon and Redwood 1970;Copper and Snell 1972;Wang et al 1975;Larson and Shah 1976) investigated the reinforcement schemes for hot-rolled steel beams, and the reinforcement schemes tested in these studies consisted of horizontal, vertical, and inclined bars welded to the web around the openings. Based on these studies the hot-rolled steel design codes have incorporated design procedures that, these days, such reinforcement D r a f t…”

The objective of this investigation was to develop an economical and an efficient reinforcement scheme for large web openings in cold-formed steel (CFS) joists in flexural zones that would restore the original moment resistance of the section. This investigation considered commonly used floor joists in North American CFS construction. Tests on joists webs with no openings and with large circular and square openings located at the mid-depth revealed that large openings can reduce the flexural strength by 23%. A reinforcement scheme was established consisting of the screw fastening of bridging channels [38.1 mm × 12.7 mm (1.5″ × 0.5″)] with the same thickness as the receiving joist, along the compression and the tensile edges of the opening, using a screw spacing of 31.75 mm. Three identical tests utilizing the proposed reinforcement scheme restored the corresponding flexural strengths of the CFS section under consideration, and the failure locations were outside the reinforced opening regions.
