the concrete strength and stiffness depends on the time of casting. It is even possible to perform the check of individual tendons, strands, reinforcement bars or concrete fibres.Īging of young concrete is properly applied in the model, i.e. The check of the cross-section (strain, stress, force) has its own tab-page for internal forces resulting from (1) prestressing (primary/secondary), (2) dead and (3) life load. The calculation of longitudinal reinforcement takes into consideration the user-defined tendons/strands and soft steel reinforcement.Īll data are clearly displayed. For instance, the required reinforcement can be determined at the ultimate limit state. Thus, the check can be performed for any time instant of the lifespan of the structure. After a successful calculation of a prestressed beam, you can easily perform the required checks for individual construction stages.
You work in the standard SCIA Engineer graphical user environment. Additionally, the check of allowable concrete and tendon stresses and the shear in the construction joint can be performed. The development of concrete strength and stiffness over time is taken into consideration in the model. All the defined construction stages can also be easily taken into account. The graphical window provides an easy check of the cross-section response, cracks, shear forces, torsion, principal stresses and capacity. The module can be used with or without the TDA (Time Dependant Analysis) module (See "TDA"). There is no difference between 2D and 3D-structures.
The module support beams of any cross-section modelled in the “Frame-XZ” or “Frame-XYZ” projects. “Checks of prestressed beams” is an advanced module for those of you who calculate prestressed beams (See "Calculation of prestressed structures") and construction stages (See "Construction Stages FEM").
