11/8/2023 0 Comments Concrete transfer beam designMax live load bending (with associated shears) and shear effects (with associated moments) have been prepared in an external ASCII file as envelopes. This load and the temporary supports are removed once the concrete has hardened. There is also a temporary load of 1.4kN/m over the length of the beam which represents temporary construction loads and the water in wet concrete. During construction the beam is initially supported on temporary supports at 1m from the beam ends. The bending and shear effects due to dead load and superimposed dead load (2.5kN/m) are created by using the “Generate” feature in the program. The dimensions of the beam can be found in example 4.3. The beam is an internal beam of a simply supported bridge deck of 21m span and the 2m wide concrete slab is cast in one. 5.2 Prestressed Beam Design Subjects CoveredĪ composite pre-tensioned pre-cast beam and concrete slab is shown below.
