Consider a three-span continuous beam ABCD, with fixed supports A & D at both ends and two interior roller supports B & C. Span AB is 3.5 meters long, BC is 4.2 meters long, and CD is 2.8 meters long. The modulus of elasticity of the beam is 200 GPa and the moment of inertia of the beam section is 400 x 100 mm. No support settlements occur at the interior supports. The said beam is to be analyzed considering live loads, with a uniform live load of 30 kN/m, while taking account pattern loadings. Pattern loadings are used to determine the maximum responses (e.g. reactions, shear, bending moments) at a certain point of the beam due to live loads. There are three types of pattern loadings: • Full Span Loading - live load is applied on all spans simultaneously; . Alternate Span Loading - live load is applied on alternate spans; and • Adjacent Span Loading-live load is applied on two adjacent spans, then skipping the next span. In the case of this problem, the following pattern loading cases should be considered: . full span loading alternate span loading (AB & CD only, BC only) adjacent span loading (AB & BC only, BC & CD only)
