8IDEA StatiCa Concrete and Prestressing

Precast roof or bridge girders of various cross-sections

Precast hollow core slabs with or without topping


Beams and design strips of ribbed or flat post-tensioned slabs in parking garages or commercial buildings


Design strip of post-tensioned slab with shallow beam

3D model of post-tensioned slab with shallow beam


Bridge piers, columns, prestressed trusses and frames in industrial buildings

12IDEA StatiCa Prestressing

Bridges cast-in-place into falsework straight or curved, prismatic or tapered


• Reinforced/Prestressed beams with composite slab

• Floors composed of prefabricated beams made subsequently monolithic by cast-in-place concrete

• Permanent shuttering floor systems

19Vertical / horizontal scaling of the beam

Draw your tendon comfortably into vertically scaled beam

20Coiling the beam back

Work simply in 2D environment and input your 3D tendon

Generate default shape of the tendon in uncoiled and scaled view of the beam

Tendon is wound up the beam and the beam is coiled back to its real shape

Unique Features


24Composite beams

Continuous composite beams made from prefabricated elements made subsequently monolithic

• Predefined types of construction stages

• Calculation of equivalent concrete age at prestressing

• Internal temporary supports with possibility of required camber

25Construction stages and TDA

• Construction stages• The effects of creep, shrinkage, and ageing• Stress redistribution in time

Non-linear calculation of creep coefficient increase economy of the design

26Improvements

Equivalent concrete ageDemoulding of prefabricated elements and the transfer of prestressing are usually done at the age of concrete less than one day. EN 1992-1-1 code does not provide the formula for strength of concrete younger than 3 days, what virtually makes the load application impossible unless the strength is based on tests. New functionality of IDEA StatiCa enables the input of strength of concrete based on tests and the calculation of equivalent concrete age. The time of corresponding construction stage is modified accordingly.

Presentation of internal forcesAn improvement in understandability and lucidity of presentation of internal forces was introduced in beam results. Total resultant of internal force can newly be presented both to centroid of entire or current composite section. In the case of the option of current section, internal forces will be related to the centroid of transformed cross-section determined from currently existing phases of cross-section and their prestressing reinforcement.

Design of necessary reinforcement (RCS)

Fast and precise design of the reinforcement necessary to comply ULS and SLS conditions

• strength in flexure, • shear, • torsion, • Interaction,• the limitations for crack width.

• The weight of shear and longitudinal reinforcement is optimized

• The design is not limited to necessary areas, but real bars

improves the economy

improves the link-up to drawings
