Analysing Numerical Modelling Behaviour of Reinforced Concrete Deep Beam with Strut-and-Tie Model
The behaviour of strut-and-tie models (STMs) as derived from truss analogue models is the subject of this chapter. STMs are frequently used to assess and model the internal force distribution of a reinforced concrete deep beam structure from the point load to the supports that carry bending, shearing, and twisting forces in disturbed zones (D-regions). Where the stress situation occurs idealised as the concrete strut, the steel tie, and the nodal area, the action of the strut and tie creates an increase in the strength of the high-reinforced concrete beam construction, the D-region on structural elements can be more easily studied. The deep beam was numerically modelled using compressive loading simulation until it collapsed. To determine deflection, cracking, and destruction of ultimate load, model modification of two diagonal reinforcements, diagonal symmetrical truss reinforcement, and diagonal frame truss reinforcement, ANSYS 3D half-span symmetrical Strut-and-Tie model deep beams modelling was done. The ultimate bending capacity, load-deformation, ductility, stress behaviour, strain, and fracture pattern of STMs have all been determined through shape modification. The numerical modelling result reveals a significant difference in STM’s deep beam behaviour.
