NUMERICAL ANALYSIS OF SELECTED PROBLEMS IN CONCRETE MECHANICS

Abstract

The presentation shows the capabilities of two modern material models for concrete to
render real behaviour of concrete elements under static loading. Three different cases are analysed
and evaluated: deterministic size effect (Wosatko et al., 2018) using a gradient enhanced damage
model developed by authors (GD), punching shear failure for flat slabs without shear reinforcement
(Wosatko et al., 2019) using Concrete Damaged Plasticity model (CDP) available in ABAQUS FEA
and failure of frame corners under opening bending moment (Szczecina, 2018), also using the CDP
model.
The results show that the modern material models for concrete are able to capture real
behaviour of concrete elements in a reliable way. However, the presented analyses point out clearly
that the choice of proper values of material model parameters has to be made with great care.
Moreover, the last presented example shows that the advanced numerical simulations for concrete
elements can be used as a design tool – in the analysed case giving a valuable insight into proper
reinforcement detailing for RC frame corners.
