What is ANSYS/CivilFEM ?® ®

ANSYS/CivilFEM is a comprehensive finite element analysis and design software package for structural engineering projects.

It combines the state-of-the art general purpose structural analysis features of ANSYS with high-end specific civil engineering-specific structural analysis capabilities of CivilFEM

As both programs are completely integrated, CivilFEM supports all types of advanced analysis supported by ANSYS running as a unique software and executable.

creating solid models.

• A solid model is defined by volumes, areas, lines, and keypoints.

• Volumes are bounded by areas, areas by lines, and lines by keypoints.

• The first step to be able to use the Advanced Prestressed Concrete module is the model creation, where the prestressed forces will be later apply either with:- Beam elements- Solid Elements

Model Creation

forANSYS

• This entity will act as the skeleton of the model, and the prestressing cables will be defined over it.• The support beam is made of cuts and segments.• The cuts are equivalent to cross sections. They have the

information about the mechanical properties of the model.• The segments represent the way cuts are connected.

Loss of Prestress• The loss of prestress calculation allows obtaining

instant and long-term prestressing losses for the tendons defined with CivilFEM editor. • Instant losses: ∆P1, ∆P2, ∆P3, ∆Px

• Friction losses (∆P1)

forANSYS

• The soil foundation stiffness (ballast module) value allows approximating the soil elastic behavior (E, ν). Its use avoids the necessity of modeling the earth underneath the structure.

• Also the average, maximum and minimum values of the module throughout foundation are available

• The soil foundation stiffness values calculated by CivilFEM are automatically send to ANSYS for the later superstructure calculations with beams shells or solid elements.
