Orientations can be graphically verified with the /ESHAPE command. Rebar specifications include the material number (MAT), the volume ratio (VR), and the orientation angles (THETA, PHI). Use the MAT command to input the concrete material properties. The element has one solid material and up to three rebar materials. The element is defined by eight nodes and the isotropic material properties. Figure 4.65-1 SOLID65 3-D Reinforced Concrete SolidĤ.65.1 Input Data The geometry, node locations, and the coordinate system for this element are shown in Figure 4.65-1. See Section 14.65 of the ANSYS Theory Reference for more details about this element. They are also capable of plastic deformation and creep. The rebars are capable of tension and compression, but not shear. The concrete is capable of cracking (in three orthogonal directions), crushing, plastic deformation, and creep. The most important aspect of this element is the treatment of nonlinear material properties.
The concrete element is similar to the SOLID45 (3-D Structural Solid) element with the addition of with special cracking and crushing capabilities. Up to three different rebar specifications may be defined. The element is defined by eight nodes having three degrees of freedom at each node: translations in the nodal x, y, and z directions. Other cases for which the element is also applicable would be reinforced composites (such as fiberglass), and geological materials (such as rock). In concrete applications, for example, the solid capability of the element may be used to model the concrete while the rebar capability is available for modeling reinforcement behavior. The solid is capable of cracking in tension and crushing in compression. SOLID65 is used for the three-dimensional modeling of solids with or without reinforcing bars (rebars). 4.65 SOLID65 3-D Reinforced Concrete Solid (UP19980821 )Ĥ.65 SOLID65 3-D Reinforced Concrete Solid
