Abstract:
Reinforced concrete deep beams subjected to two movable loads with constant distance were designed using strut-and-tie model, making it possible to design based on reasonable theory. Strut-and-tie model of topology change for deep beams with two applied loads were properly established and the equations for computing tension in tie and compression in strut were developed. An example was included to demonstrate its use. The results show that the tension in tie approachs maximum when the loads move to a certain location close to mid-span, which will determine the required area of longitudinal tension reinforcement; and the compression in strut approachs maximum when the loads move to a certain location close to support, which will determine the geometry of the deep beam and the compression strength of concrete.
