Dear Abaqus users,
Iam modeling and analysing a simply supported RC Slab with Concrete Damaged Plasticity on Abaqus CAE. Concrete slab is modelled with C3D20 solid elements and steel bars are modelled on Truss element T3D2 which are embedded into concrete. My results show very high force vs deflection graph, i.e. the loading force is high (around 800-100kN) when the behavior of slab begins to yield. These values are far out when compared to my experimental test results which is around 80kN. I have chosen a tensile stress of concrete to a minimum value of 0.05 to 0.1% of fcu (41.24N/mm2), i.e. around 2.06 to 4.12 N/mm2, for Abaqus input tensile behavior. My query is that how to lower down the force vs graph curve so that it would match the experimental tests results? Thanks in advance for any kind helps.
