Post-tensioned Tendons: The 3D tendon line geometry can be defined by non-uniform B-splines for calculation of frictional and pressure forces due to a sequence of applied end forces and length changes from anchorage set when concrete structures modeled by beam elements are post-tensioned.User-defined Beam Sections: The external and internal boundaries of arbitrary sections can be decribed using straight and circular line segments and the section properties including shear center location and the warping constant can be calculated.
Laminated Materials: Shell section with orthotropic layers of different orientations, failure criteria.
The SOLVIA System offers integrated pre- and post-processing and consists of: Sparse Solver: Storage of system matrices in a sparse format has been implemented and in combination with a parallel direct sparse solver very significant solution time savings can be observed for static as well as dynamic cases, in particular for analysis of large models.
Frequency, complex harmonic and temperature analyses of large models show also very significant decreases in solution times.
The objective function is formed by the residuals between analytical and measured natural frequencies.
Single-objective optimization with equal weights of natural frequency residual of each mode is used for optimization computation.
