The objective of this work is to discuss the possibilities of modeling reinforcement detailing of reinforced concrete models in practical use. To carry out the analytical investigations, the structure is modeled in a Finite Element software ANSYS. The specimens are modeled as (i) discrete model and (ii) smeared model.
The modeling analysis: The results of different models available on ANSYS to simulate the concrete behavior and analyzing the push out test model given in Table 1 are illustrated in Fig. 4 and 5 for discrete and smeared reinforcement, respectively. These figures show that the load-deflection curves show very close results at the early stages of ...
frames with ANSYS  since it is a sophisticated software with a 3D eight-node isoparametric FE element which can be used to model concrete material and its cracking behavior. ANSYS modeling of reinforced concrete structures has been studied by many researchers [2-12] In this study, the FE model of an R/C frame fabricated and experimentally tested concrete, In this study, the Poisson’s ratio of concrete is assumed to be 0.2 (Bangash, M. Y. H., 1989). Drucker-Prager model in ANSYS required three parameters cohesion, friction angle and Dilatancy angle, to obtain the cohesion and friction angle; the equations (11) and (12) may use. Figure (4) showed the Drucker-Prager model in ANSYS.

Introduction Concrete is a very strong material in compression and reinforcing steel in tension. But their integrated action and good bonding is vital for structural strength and serviceability. This
Because I Model the Reinforced Concrete Column in Ansys , I Know in this way exist many Problems . for the first wirk , you must do three steps : 1-Modeling Plain Concrete . 2-Modeling Reinforced Concrete ( If You Want to Model wrapped reinforced Concrete ) . 3-Modeling wrapped Reinforced Concrete . It has predefined templates for the ease of modelling such complicated structures. Etabs - Mostly used for Multi Storey/ High Rise buildings. High end analysis applications for such structures: Time dependent material properties like creep and shrinkage, construction stage analysis, Column shortening Analysis can be performed.
I want to find the Poisson's ratio of a 3D model, not the material but the model. How can I do this in ANSYS workbench? I am using this formula, but I can't get it to work with different models. Nov 21, 2015 · For modeling concrete structure in ANSYS, Solid65 element type is used. This solid is capable of cracking in tension and crushing in compression . In this tutorial, the use of value -1 for uniaxial crushing stress removes crushing capability and cracking of the concrete control the failure of the finite element model .

The viscoplastic law of Perzyna represents the rockmass behavior. The concrete, shotcrete or precast, is modeled as a viscoelastic material through the Maxwell and Kelvin chain models. Finite element simulations are performed by incorporating subroutines for viscoelastic concrete models in the ANSYS code. A. For experimental and analytical investigation • Experimental Mix design of concrete for desired strength Casting of beams with same proportion as concrete cylinder Test of concrete cylinder at 7 days and 28 days Test of mild steel Test of beam at 28-days • Analytical Steel concrete composite construction has gained wide acceptance as an alternative to pure steel or concrete construction. Ansys 11 computer program has been used to develop a three-dimensional nonlinear finite element model in order to investigate the fracture behaviors of continuous double steel-concrete composite beams, with emphasis on the beam slab interface.

I want to find the Poisson's ratio of a 3D model, not the material but the model. How can I do this in ANSYS workbench? I am using this formula, but I can't get it to work with different models. For modeling of concrete the ANSYS used an element named as Solid65 which is non linear model of brittle material similar to concrete. It was an eight node solid iso parametric element with three degrees of freedom at each node. Mechanical APDL (Classic) ANSYS can be used to model the solid65 concrete element with the link 180 to model rebar or one can also smear the rebar within the solid65 element itself (be careful to define correct orientation and % of element area).
