The design of ‘stub girders’ is presented in a form consistent with BS 5950: Part 3. The basis of design is simplified by considering that the steel bottom chord resists tension (arising from bending action), vertical shear, and local (Vierendeel) moments across the opening. The design method is compared with the results of three full-scale stub girder tests and is shown to be conservative but reasonably accurate. Model factors for these tests were in the range of 1.0 to 1.2 when using measured material strengths, increasing to 1.2 to 1.w4 hen using design strengths.
One important observation was that the Code requirements for transverse reinforcement are unduly conservative for this form of construction. A design example is included, which covers the important aspects of the design.
