Analytical 3D tendon element derived from geometrical tendon layout.Semiautomatic generation of grillage model.Calculation of cross-section properties for arbitrary cross-sections.
ALLPLAN MANUAL MANUAL
Automatic or manual numbering of beam elements.The product analysis the exact position of the tendon relative to the girder and assigns the corresponding beam elements to the tendon automatically. The analytical model for tendons is also generated from their geometrical geometry. The element numbers are assigned automatically, and the user must choose only the material. One of the additional analysis relevant definition that need to be made is the definition of the degrees of freedom (DOF) of a spring element.įurther analysis relevant definitions need to be specified on the girder level. Furthermore, it defines into how many beam elements the super- or substructure needs to be subdivided. By using “Structural units” the user specifies, which bridge parts contribute to the structural system and which need to be considered only as load. Some of the analysis relevant definition start already in the cross-section definition. This automated process is completely user controlled. With some minor analysis relevant definitions, the geometrical model is complemented, and the analytical model can be generated automatically. In Allplan Bridge the structural model does not need to be modelled from beginning but the existing geometrical model is used as a basis. The detailing model subdivide into construction segments automatically.Interactive 3D assignment of construction segments.Gantt diagram for definition and visualization.This allows to analyze different schedule variants and, on this way, to optimize the construction sequence. The related structural components are interactively assigned to these tasks and this assignment connects the time attributes to the structure.įurthermore, in Allplan bridge it is possible to define different schedules for the same bridge structure.

In this way the chronological shift of phases and/or tasks is easier, and the user has full control on how this affects previous and subsequent definitions. The next time attribute that needs to be defined is the duration of the task. The starting day can be defined as global day or relative to the phase begin. The begin of a task can be defined as starting date or starting day. The construction plan is divided into several phases and further into individual tasks, such as concrete hardening, tendon stressing, activation of self-weight etc. In Allplan Bridge, the time as 4th dimension is considered when specifying the construction process. This point grid facilitates copying and mirroring of the tendon in longitudinal and transverse direction. When calculating the detailed tendon geometry, the program determines these values automatically, using an intelligent algorithm minimizing the friction losses in the stressing process.Ī special point grid is available in the cross-section to ease the specification of the tendon position in the cross-section plane.
Selective parameters can be defined as variable. In addition, direction angle and curvature radius of the tendon can be specified in each point.
Each 3D Tendon point is specified by the position along the axis, and the position in the cross-section in relation to a reference point. Allplan Bridge 2019 makes it easy to model a wide range of types of pre-stressing: with immediate or later bond, internal and external, longitudinal, transverse and vertical, as well as with non-standard geometry.īased on user-defined 3D points, the program automatically generates the geometry of a tendon along the bridge structure.
