Experimental study on U-Shaped steel girders using different connectors

U-shaped steel girders are a kind of structural steel that is often utilized in the construction industry. This article examines the two types of connectors used in u-shaped steel girders to determine which has the least deflection. The flexural test and compressive strength of the specimens were examined experimentally by the authors. Two u-shaped steel girders with a length of 1100mm, a span of 300mm, a depth of 100mm, a bottom plate of 75mm, and 35mm flanges each were constructed to test the endurance of two connections in this scenario. This experiment employed l-shaped angled connections and stud/shear connectors. After 28 days of curing, each specimen was tested. The effectiveness of each combination was examined in order to provide design suggestions. When compared to standard composite beams, a U-shaped steel-concrete composite girder offers stronger flexural resistance, good fire resistance, and improved sound insulation owing to the infilled concrete. However, there has been researching on the shear resistance of angle-shaped connections in U-shaped composite beams, making it difficult to determine which shear connector is best for U-shaped composite beams. According to previous studies, U-shaped composite beams with headed stud shear connections and steel angles all had an excellent flexural performance.
