    Range of application

    The program is suitable for a wide range of pre- and post-tensioned concrete structures.

    Prefabricated beams

    with various CSS

    Bridge piers, columns,

    prestressed trusses and frames

    Beams and design strips

    of post-tensioned slabs

    Continuous beams

    with composite slab

    Civil and industrial buildings

    Bridge structures

    Bridges cast-in-place

    into falsework

    Precast hollow core slabs

    with or without topping

    Easy to Use, Correct and Complete Solution

    Distinctive features of composite design module are completeness, comprehensiveness. Design methods fully comply

    with complex Eurocode and SIA code requirements. At the same time the solution is easy to use and effective for daily

    needs of industry professionals. Fast and simple input is done with help of specialized wizard. All data related to the analysis

    of construction stages is generated automatically and they are presented in terms well known to the engineers, such as load

    cases, combinations etc. Therefore they need not to adapt their workflow and logic to the complex method of analysis.

    The objective was to provide correct and complete solution & make it easy. So the program is focused, simple, and fast tool

    rather than generic and complicated puzzle.

    The definition of tendon geometry related to the shape of a designed structure can be a difficult design step

    especially in case of curved structures. IDEA StatiCa Prestressing provides for the uncoiling of the beam

    and simplifies this step plus, you work in 2D and you make a 3D structure.

    3D problem

    By uncoiling the beam in the plan we simplify the problem to 2D geometry. Consequently the beam appears

    straight in XY and XZ planes and the definition of tendon geometry is no longer a challenging task.

    Uncoiling

    The next step can be a complex job, which is the drawing of tendon shape in a slender prestressed beam!

    It can be very challenging, because the beams are usually very long and shallow and one can hardly differentiate

    the tendons details. That is why we offer the possibility to scale selected element vertically and horizontally.

    Vertical and horizontal scaling

    Tendon shape design

    Scale your beam vertically to obtain clear drawing in comfortable arrangement.

    Design of tendon shape in 2D environment

    Once we have prepared the uncoiled and scaled view of the beam, we can generate a default shape of the tendon automatically,

    also with respect to support positions. If needed, the tendon shape can be adapted to meet any user defined requirements.

    The magnitude of prestressing effects is controlled by prestressing force. According to Prof. T.Y. Lin, a portion of an external

    load has to be balanced by the equivalent load caused by prestressing. The Load balancing method can therefore be used

    for preliminary design of the prestressing force.

    Default shapes of tendon with extensive predefined shapes parabolic/polygonal

    Import from TXT, DXF

    User-defined templates

    A 3D tendon profile is obtained by composing XY and XZ plane projections. In addition, the tendon is wound up the beam

    and the beam is coiled back to its real shape. In this way we obtain tendon geometry related to curved shapes of a designed

    beam quickly with no additional effort! As it is documented here by the examples, the effort is reduced to the situation

    of straight beams.
